Our blood cells can become affected by blood cancer. In the UK, more than 40,000 people receive a blood cancer diagnosis each year, and more than 250,000 people are presently coping with the disease.

What is Blood Cancer?

A broad category of cancers that might damage your blood, bone marrow, or lymphatic system is referred to as blood cancer. When something goes wrong during the production of your blood cells, it occurs. Blood cancer is brought on by modifications (mutations) in blood cells' DNA. Your blood cells can become affected by blood cancer. Some of the most prevalent types of blood cancer include leukaemia, lymphoma, and myeloma. Additional types include MPNs and MDS.

Types of Blood Cancers

Three main types of blood cancers are:

  • Leukaemia: It is a specific kind of cancer that develops in the bone marrow and blood, and it is brought on by the rapid creation of aberrant white blood cells. Because there are so many aberrant white blood cells, the bone marrow cannot make enough red blood cells or platelets to fight infection.

  • Lymphoma: It is a specific kind of blood cancer that impacts the lymphatic system, which eliminates extra fluid from the body and generates immune cells. White blood cells called lymphocytes fight infection. The lymphoma cells that develop from abnormal lymphocytes grow and accumulate in your lymph nodes and other tissues. These malignant cells weaken your immune system over time.

  • Myeloma: The cancer is a plasma cell cancer. White blood cells, called plasma cells, help your body create antibodies that fight infections and disease. Myeloma cells stop the body from producing antibodies normally, weakening your immune system and making you more vulnerable to infection.

Overview

Our blood, which makes up roughly 8% of your average body weight, has a significant impact on how your body works. All of your organs receive oxygen, nutrition, hormones, and antibodies from your blood as it travels through your vascular system. Plasma is the fluid that carries cells, waste, and nutrients, among other things, and blood cells make up about equal amounts of blood (red blood cells, white blood cells and platelets).

Usually, an abnormal and excessive proliferation of white blood cells is the cause of cancer in the blood. About 10% of all malignancies that are diagnosed each year in the United States are blood cancers. Leukaemia, lymphoma, and myeloma are among the blood malignancies that affect more males than women. About 25% of all paediatric malignancies are caused by childhood leukaemia.

Active surveillance without cancer-directed therapy to conventional cancer treatments like immunotherapies, chemotherapies, and targeted medicines are all options for treating blood malignancies. The fact that there are now over 100 different forms of blood malignancies makes a proper diagnosis crucial before choosing a course of therapy, according to Dr Huntington.

Risk Factors of Blood Cancers

Although it is thought that a mix of hereditary and environmental factors contribute to the development of blood cancers, the risk factors for blood cancer are not entirely known. Smokers, radiation or chemically exposed individuals are more likely to acquire certain forms of blood cancers. Additional risk factors for lymphomas and leukaemias include infections with the Epstein-Barr virus, HIV, and human T-cell lymphoma/leukaemia virus.

How is Blood Cancer Diagnosed?

Leukaemia: The results of a complete blood count (CBC) test, which measures the ratio of white blood cells to red blood cells and platelets, will be given to your doctor.

Lymphoma: A biopsy, which involves removing a small piece of tissue to be inspected under a microscope, will be required by your doctor. To look for swollen lymph nodes, your doctor may occasionally additionally request an X-ray, CT, or PET scan.

Myeloma: To identify the chemicals or proteins created as a result of myeloma development, your doctor may conduct a complete blood count (CBC) or other blood or urine tests. Bone marrow biopsy, X-rays, MRIs, PET scans, and CT scans can occasionally be used to determine the existence and degree of myeloma spread.

Treatments for Blood Cancer

Many variables will affect the course of treatment. Your age, the type of blood cancer you have, how quickly it is spreading, and whether or not it has spread to other parts of your body are a few of these factors.

Numerous types of blood malignancies are now very curable since blood cancer treatments have significantly improved over the past few decades. The following are typical treatments:

  • Chemotherapy: To kill and stop the growth of cancer cells, anticancer medications are injected into the body (or occasionally taken as pills).

  • Radiation therapy: High-energy rays are used in this type of cancer treatment to destroy cancer cells.

  • Targeted therapies: Drugs are used in this type of cancer treatment to specifically attack cancerous blood cells while sparing healthy ones. The most typical kind of treatment for leukaemia is targeted therapy.

  • Stem cell transplantation: After receiving treatment to eliminate cancerous blood cells, your body can be infused with healthy stem cells to assist in resuming the creation of healthy blood.

  • Cancer Surgery: Some lymphomas can be treated with this procedure, which entails removing the afflicted lymph nodes.

  • Immunotherapy: With this therapy, the immune system is triggered to target and destroy cancer cells.

Facts about Blood Cancers

  • In the United States, one person is given a leukaemia, lymphoma, or myeloma diagnosis every three minutes.

  • In the US, 186,400 individuals are anticipated to receive a diagnosis of leukaemia, lymphoma, or myeloma in 2021.

  • The anticipated 1,898,160 new cancer cases that will be diagnosed in the US in 2021 will include 9.8% of new cases of leukaemia, lymphoma, and myeloma.

Death Rate

  • A person with blood cancer passes away in the US every 9 minutes on average. More than six people each hour, or over 158 persons per day, are represented by this statistic.

  • In the US, an estimated 57,750 people will pass away from leukaemia, lymphoma, and myeloma in 2021.

  • Based on the predicted number of 608,570 cancer deaths in 2021, these disorders are anticipated to cause 9.5% of cancer-related deaths.

Symptoms in Different Skin Tones

Bruises: Typically, patches begin as red and gradually turn another colour and become darker. They frequently feel soft. Bruises on black and brown skin may be hard to spot at first, but as they get worse, they become darker than the surrounding skin.

Rashes: Frequently manifest as bigger blotches or groups of small spots (petechiae) (purpura). They may seem purple or darker than the surrounding skin on black and brown skin. They usually seem red or purple on lighter skin. The petechiae and purpura don't fade if you press on them.

Paleness (pallor): Pallor is frequently more obvious right away on light skin. People with black or dark skin may seem greyish and have paler-than-normal palms. Pallor in their lips, gums, tongue or nail beds may also be noticed. Pallor is visible in all skin tones by lowering the bottom eyelid. If the inside is pale pink or white instead of the usual dark pink or red, it is a sign of pallor.

What are the Early Signs of Blood Cancer?

One of the most important components of our body is involved in blood cancer. Blood circulates throughout our body, supplying the organs with oxygen, nutrition, hormones, and antibodies while also removing waste products and pollutants. When cancer develops in the blood, it impairs its functionality and causes a wide range of diseases. Depending on the type, blood cancers present various symptoms.

In its early stages, blood cancer typically exhibits no distinctive symptoms. However, the following warning signs and symptoms are concerning, so you should discuss them with your doctor:

  • Slow healing: Do not ignore a wound that is taking longer than usual to heal, and call your doctor. Due to low platelet levels, which are essential for blood clotting and wound healing, people with leukaemia frequently bleed and get bruised.

  • Quickly gets sick: Low amounts of white blood cells and plasma cells, which create antibodies and defend humans from several illnesses, are found in blood cancer patients. Consequently, a person with blood cancer is sick more often and is sick for longer than usual.

  • Diminished immunity: Due to decreased disease-fighting blood cells and poor lymphatic drainage, the individual with blood cancer has a weakened immune system and is susceptible to infection.

  • Lumps and swelling: One may experience swelling or an odd mass in the lymph nodes, including the tonsils, testicles, or armpits.

  • Rectal bleeding: When urinating, bloody discharge may be observed.

  • Change in urinary habits: Blood in the urine or a burning sensation are two symptoms of blood cancer (hematuria).

  • Skin changes: Blood cancer patients may experience bleeding, rashes, and bruising. On people with different skin tones, these symptoms may seem differently coloured.

  • Pallor: Due to an inadequate supply of red blood cells in their bodies, people with blood malignancies may seem extremely pale.

Blood Cancer Prevention

The majority of blood cancers still cannot be prevented, despite extensive research. Although there are no known absolute risk factors for this malignancy, lowering the known ones is crucial. Additionally, carrying out some of these easy tasks will strengthen your immunity and help to somewhat lower the risk.

  • Avoid Exposure to Radiations: Avoid high radiation doses as much as you can because during several treatment procedures, patients are frequently exposed to high-intensity radiation, increasing their risk of dying from blood cancer.

  • Avoid Exposure to Chemicals: Avoid exposure to certain dangerous chemicals, such as pesticides, as this may raise your risk of developing blood cancer. If your line of work requires you to be around hazardous substances, you must take the necessary precautions. The likelihood of this malignancy can also rise with benzene exposure.

  • Avoid Smoking or Tobacco in Every Form: The use of tobacco products, such as cigarettes, should be entirely avoided as it poses a significant risk for several diseases, including cancer.

  • Regular Exercise: The body needs exercise on a regular basis to stay healthy. There are fewer chances of developing blood cancer if you exercise for 30 minutes each day, but there is currently no proof to back this up.

  • Eat Healthily: Consuming nutritious diet aids in the prevention of diseases. The risk of blood cancer is somewhat decreased by increasing the consumption of fresh produce that is high in fibre and minerals.

Background

  • Today, more than 1.3 million Americans either have blood cancer or are in remission from it.

  • The majority of paediatric malignancies, or 28% of all cancers in children, are leukaemias. In the United States, there will be 178,520 new instances of leukaemia, lymphoma, and myeloma diagnosed in 2020, with 56,840 deaths anticipated as a result of the diagnosis.

  • Given how many individuals these malignancies continue to afflict, it's critical to comprehend the illness and what we can do to increase our chances of surviving it.

Frequently Asked Questions (FAQs)

1. What is the main cause of blood cancer?

Changes (mutations) in the DNA of blood cells are the root cause of all blood malignancies. The blood cells begin to behave strangely as a result of this. These changes are frequently related to factors outside of our control. They are not hereditary defects that can be passed down to offspring because they occur during a person's lifespan.

2. What is the first stage of blood cancer?

The lymph nodes grow during the first stage of blood malignancy. This occurs as a result of a sudden rise in lymphocyte density. Since cancer has not yet progressed or impacted any other physical organs, the risk is quite minimal at this point.

3. How do blood cancers spread?

Any lymphoid or blood-forming cell has the potential to develop into a leukemic cell. After that, the cell divides to make numerous other cancer cells. These cells may eventually outnumber the bone marrow, overflow into the blood, and invade other tissues.

4. Where is blood cancer found?

Our blood cells' ability to produce and perform is impacted by blood malignancies. Your bone marrow, where blood is made, is where the majority of these malignancies begin. Your bone marrow is where stem cells mature and give rise to red blood cells, white blood cells, or platelets.

5. What age is blood cancer common?

Age is a factor in most leukaemia risks. Patients with acute myeloid leukaemia (AML), chronic lymphocytic leukaemia (CLL), or chronic myeloid leukaemia (CML) are typically 65 years of age or older at the time of diagnosis. However, those under the age of 20 account for the majority of instances of acute lymphocytic leukaemia (ALL).

6. How do epigenetic changes contribute to blood cancer development?
Epigenetic changes alter gene expression without changing the DNA sequence. In blood cancers, these changes can activate oncogenes or silence tumor suppressor genes. Examples include DNA methylation and histone modifications. Understanding these changes has led to the development of epigenetic therapies, such as DNA methyltransferase inhibitors, which can reverse some of these harmful modifications.
7. How do blood cancers affect blood clotting, and what are the implications?
Blood cancers can disrupt normal blood clotting in several ways:
8. What is the role of the tumor microenvironment in blood cancers?
The tumor microenvironment refers to the surrounding non-cancerous cells, molecules, and blood vessels that interact with cancer cells. In blood cancers, it plays several important roles:
9. What is the role of apoptosis in blood cancer development and treatment?
Apoptosis, or programmed cell death, is a crucial process in maintaining healthy cell populations. In blood cancers:
10. What is the importance of the blood-brain barrier in treating blood cancers?
The blood-brain barrier (BBB) is a protective layer that prevents many substances, including some cancer drugs, from entering the brain. This is significant because:
11. What is the role of angiogenesis in blood cancer progression and treatment?
Angiogenesis, the formation of new blood vessels, plays a crucial role in blood cancers:
12. How do blood cancers affect the production and function of platelets?
Blood cancers can impact platelets in several ways:
13. How do blood cancers affect bone health, and what are the implications?

15. How do blood cancers affect the production and function of eosinophils and basophils?
Eosinophils and basophils, types of white blood cells involved in allergic responses and fighting parasites, can be affected by blood cancers:
16. How do blood cancers affect the body's ability to fight infections?
Blood cancers compromise infection-fighting ability in several ways:
17. What is the significance of flow cytometry in diagnosing and monitoring blood cancers?
Flow cytometry is a powerful technique that analyzes individual cells based on their physical and chemical characteristics. In blood cancer diagnostics, it's used to:
18. What is the significance of chromosomal abnormalities in blood cancers?
Chromosomal abnormalities, such as translocations or deletions, play a crucial role in many blood cancers. These genetic changes can activate oncogenes or inactivate tumor suppressor genes, leading to uncontrolled cell growth. Identifying specific chromosomal abnormalities helps in diagnosis, prognosis, and treatment selection, as some targeted therapies are designed to address particular genetic mutations.
19. What is the significance of the Philadelphia chromosome in certain leukemias?
The Philadelphia chromosome is a specific genetic abnormality found in chronic myeloid leukemia (CML) and some cases of acute lymphoblastic leukemia (ALL). It results from a translocation between chromosomes 9 and 22, creating the BCR-ABL fusion gene. This gene produces an abnormal protein that drives cancer cell growth. The discovery of this chromosome led to the development of targeted therapies like imatinib, dramatically improving treatment outcomes for CML.
20. What is the significance of minimal residual disease (MRD) testing in blood cancer treatment?
MRD testing detects very small numbers of cancer cells remaining after treatment. It's important because:
21. How do epigenetic changes contribute to drug resistance in blood cancers?
Epigenetic changes, which alter gene expression without changing the DNA sequence, can contribute to drug resistance in blood cancers by:
22. What is the significance of circulating tumor DNA (ctDNA) in blood cancer management?
Circulating tumor DNA refers to fragments of DNA released by cancer cells into the bloodstream. Its analysis is important because:
23. What is the role of cytokines in blood cancer progression and symptoms?
Cytokines are signaling molecules that play a crucial role in blood cancer:
24. What is the role of stem cell transplantation in treating blood cancers?
Stem cell transplantation replaces diseased bone marrow with healthy stem cells. This can be done using the patient's own stem cells (autologous) or a donor's (allogeneic). The goal is to restore the body's ability to produce healthy blood cells after high-dose chemotherapy or radiation has destroyed the cancerous cells along with normal bone marrow.
25. How do targeted therapies work in treating blood cancers?
Targeted therapies are drugs designed to attack specific molecules or pathways crucial for cancer cell growth and survival. Unlike traditional chemotherapy, which affects all rapidly dividing cells, targeted therapies are more precise. They can block specific proteins, interfere with cell signaling, or deliver toxic substances directly to cancer cells, often with fewer side effects than conventional treatments.
26. How does the bone marrow microenvironment contribute to blood cancer progression?
The bone marrow microenvironment, consisting of various cell types and signaling molecules, can support the growth and survival of cancer cells. It provides nutrients, growth factors, and protection from the immune system. Understanding this interaction has led to therapies that target not just the cancer cells but also their supportive environment.
27. What is minimal residual disease (MRD) and why is it important in blood cancer treatment?
Minimal residual disease refers to the small number of cancer cells that may remain after treatment, even when the patient appears to be in remission. Detecting MRD is crucial because these remaining cells can lead to relapse. Advanced techniques like flow cytometry and PCR can detect very low levels of cancer cells, helping guide treatment decisions and predict outcomes.
28. What is the role of the spleen in lymphoma, and why might it be removed?
The spleen, part of the lymphatic system, can be involved in certain lymphomas. It may become enlarged (splenomegaly) due to accumulation of cancerous cells. In some cases, the spleen is removed (splenectomy) to help diagnose the specific type of lymphoma, relieve symptoms caused by an enlarged spleen, or as part of the treatment plan. However, this decision is carefully weighed as the spleen plays important roles in immune function and blood cell recycling.
29. What are the three main types of blood cancer?
The three main types of blood cancer are:
30. How does leukemia differ from lymphoma?
Leukemia primarily affects the bone marrow and blood, causing an overproduction of abnormal white blood cells. Lymphoma, on the other hand, affects the lymphatic system, including lymph nodes, spleen, and other organs. Leukemia is generally a disease of the blood and bone marrow, while lymphoma is a cancer of the immune system.
31. What are B-cells and T-cells, and how are they involved in lymphoma?
B-cells and T-cells are types of lymphocytes (white blood cells) crucial to the immune system. B-cells produce antibodies, while T-cells directly attack pathogens. In lymphoma, either B-cells or T-cells can become cancerous, leading to B-cell lymphomas or T-cell lymphomas, respectively.
32. What is the difference between acute and chronic leukemia?
Acute leukemia progresses rapidly, with immature blood cells (blasts) multiplying quickly. Chronic leukemia develops more slowly, with more mature, abnormal cells. Acute leukemia requires immediate treatment, while chronic leukemia may not need immediate intervention and can sometimes be monitored.
33. What are common symptoms of blood cancer?
Common symptoms of blood cancer include:
34. Why do blood cancer patients often experience fatigue?
Fatigue in blood cancer patients is often due to anemia (low red blood cell count). Cancerous cells can crowd out normal blood-forming cells in the bone marrow, leading to decreased production of red blood cells. This results in less oxygen being transported throughout the body, causing fatigue.
35. How does multiple myeloma affect the body?
Multiple myeloma affects plasma cells, a type of white blood cell that produces antibodies. Cancerous plasma cells accumulate in the bone marrow, interfering with normal blood cell production. This can lead to bone damage, kidney problems, anemia, and increased susceptibility to infections.
36. How does blood cancer affect the immune system?
Blood cancers can compromise the immune system in several ways:
37. How do blood cancers affect red blood cell production, and what are the consequences?
Blood cancers can interfere with red blood cell production in the bone marrow, leading to anemia. This occurs because:
38. What is blood cancer and how does it differ from other types of cancer?
Blood cancer is a group of diseases that affect blood cells and bone marrow. Unlike solid tumors, blood cancers typically don't form masses. Instead, they interfere with normal blood cell production and function. The main types are leukemia, lymphoma, and myeloma, each affecting different blood cell types or components of the immune system.
39. How do monoclonal antibodies work in treating blood cancers?
Monoclonal antibodies are engineered proteins that target specific molecules on cancer cells or immune cells. In blood cancers, they can work in several ways:
40. What is the role of CAR T-cell therapy in treating blood cancers?
CAR T-cell therapy is a form of immunotherapy where a patient's T-cells are genetically modified to express chimeric antigen receptors (CARs). These CARs allow the T-cells to recognize and attack cancer cells more effectively. This therapy has shown remarkable success in certain types of leukemia and lymphoma, especially in cases that have not responded to other treatments. It represents a significant advance in personalized medicine for blood cancers.
41. How does radiation therapy work in treating blood cancers, and what are its limitations?
Radiation therapy uses high-energy rays to kill cancer cells. In blood cancers, it's often used:
