There are lots of types of cancers that affect the blood, the bone marrow, and the lymphatic system. We call these blood cancers. Blood cancers are different from other types of cancer because the bad cells can move all around the body. This makes them really hard to find and treat.
These treatments have been helping people with blood cancers live longer for the past few decades. Blood cancers are still very serious. Blood cancer patients are living longer because of these new treatments. In fact, with treatment, some cancer patients may lead long, robust, and normal lives even in the absence of the illness.
In this guide, we will try to answer questions like Is blood cancer curable, and if yes, what are the measures that need to be considered?
What is Blood Cancer?
Blood cancer is a collective term for different cancer types primarily affecting the blood, bone marrow, and spleen. It works by disorganizing the regular blood cell functions; thus, there is excessive production of abnormal cells. Blood cancer is mainly categorized into three types, namely leukemia, lymphoma, and myeloma.
The Three Major Types of Blood Cancers
Myeloma
Myeloma, sometimes referred to as multiple myeloma, is a form of blood cancer that originates in the plasma cells of the blood. Plasma cells are produced by the white blood cells in the bone marrow. This cell is entrusted with the task of protecting our body by making a defensive protein called immunoglobulin.
Once a plasma cell becomes cancerous, it excessively proliferates in the bone marrow and produces an abnormal amount of immunoglobulin. This results in the weakening of the bones, bone pain, and bones that fracture very easily, as well as an increase in the calcium level in the blood. Immunoglobulin travels in the blood and passes through the kidneys, which get damaged. These unusual proteins are recognizable by the electrophoresis test as the M Band in blood and urine. The surplus of malignant plasma cells results in the suppression of normal blood cell production, which in turn leads to anemia, increased vulnerability to infection, and in some cases, a low platelet count.
Lymphoma
Lymphoma is the abnormal growth of lymphocytes, which results in swelling, usually in the lymph nodes, which are located in the neck, armpit, and groin areas.
There are two main types of lymphoma:
- Non-Hodgkin lymphoma
- Hodgkin lymphoma
These two types of lymphomas have more than 50 subtypes. It is diagnosed by the biopsy of the lymph node or swelling. Subtyping is done by the Immunohistochemistry test and molecular tests on the biopsy. Accurate subtyping is necessary for proper treatment.
Leukemia
Leukemia is a malignant blood disorder that originates in the bone marrow and then spreads to the blood. Clinicians are quite capable of identifying the cancer cells during routine blood testing, a complete blood count, or when they examine a peripheral smear.
Such cancer cells, when they become excessive in number, eliminate healthy blood cells by "pushing them out". For this reason, individuals with leukemia usually suffer from anemia, experience fatigue, and have infections or fevers quite often. Also, bleeding or bruising takes place as the platelet count decreases. Some of them even report bone pain or an unexpected swelling.
Blood Cancer Symptoms
Symptoms of blood cancer vary significantly with the type and extent of the disease. Typically, blood cancer causes a person to be very tired, weak, and have pale skin from anemia (a deficiency of red blood cells).
When there is a lack of normal white blood cells, which are also unable to function properly in infection, fighting bacteria, infections that last very long, or recur frequently, may be another symptom.
Weighing less without thinking, feeling pain in the bones or joints, and bruising and bleeding easily may be some other symptoms. On top of that, the swelling of lymph nodes or spleen, particularly in cases of lymphoma, may be looked for. However, there can also be night sweats, difficulty in breathing, and no desire to eat.
Causes of Blood Cancer
Genetic Mutations
Blood cancers show different genetic mutations and chromosomal abnormalities. For example, the Philadelphia chromosome in Chronic Myelogenous Leukemia, and gene mutations like TP53 and JAK2 in various leukemia and lymphoma types.
Family History
If there is blood cancer in your close family, you are considered to be at a higher risk of getting it because certain genetic components that regulate the immune system can be passed down from parents to children.
Exposure to Radiation and Chemicals
Exposure to extremely high doses of radiation (for example, during nuclear accidents or radiation therapy) as well as certain chemicals, such as benzene, has been associated with a higher risk of blood cancers, especially leukemia.
Chemotherapy Regimens
There is a possibility of developing secondary blood cancers, such as leukemia, in cancer patients who have been treated with chemotherapy.
Viral Infections
There are viruses known to be the cause of various infections, including Epstein-Barr virus (EBV), human T-lymphotropic virus (HTLV-1), and human immunodeficiency virus (HIV), which have been linked to an increased risk of lymphoma and other haematological malignancies.
Is Blood Cancer Curable?
The answer to the question of a cure for blood cancer lies primarily in the characterisations and stage of the blood cancer at the time of diagnosis.
In most situations, the potential for a cure is very high if treatment commences early; conversely, if the disease has been untreated for a protracted period of time and has progressed to an advanced stage, the treatment is usually directed towards palliation and extending survival, and the likelihood of achieving a cure is extremely unlikely.
The likelihood of curing blood cancer depends on various factors. Firstly, the type of blood cancer diagnosed and the period when it is diagnosed are quite important aspects in deciding whether the blood cancer will be cured or not. In fact, children suffering from Acute Lymphoblastic Leukemia can recover thanks to new therapies in quite some cases. Blood cancers like Hodgkin’s Lymphoma, if discovered in early stages and subjected to chemotherapy or radiation, can even be cured.
On the other hand, some blood cancers, like the mentioned Multiple Myeloma and certain chronic leukemias, are very challenging to cure. Utilising the new drugs, doctors can make these patients' conditions better and even grant symptom disappearance for some time.
Nowadays, novel therapies like targeted therapies and stem cell transplants have extended the life expectancy of people with blood cancer. Being a disease, blood cancer is currently treated with a changing mix of therapy options and new drugs; thereby, this condition is becoming increasingly manageable for patients.
Diagnosing Tests for Blood Cancer
There are many important steps involved in the diagnosis of blood cancer:
Physical Exam
The doctor will perform a physical check-up to find the signs of blood cancer, such as swelling of lymph nodes, muscle or liver enlargement, or bleeding or bruising that is unusual.
Blood Tests
Complete Blood Count (CBC)
This is a test that counts the number of red blood cells, white blood cells, and platelets. A count that is not normal can indicate a blood cancer.
Blood Smear
Blood cells are examined under a microscope in this test to see if there are any abnormalities in the size, shape, or number of cells.
Blood Chemistry
This test determines the level of certain substances in the blood. A variation in the amount of proteins or enzymes in the blood can indicate a blood cancer.
Bone Marrow Tests
Bone Marrow Aspiration
This test uses a needle to withdraw liquid bone marrow samples from the hip bone. The sample is then analyzed for the presence of cancer cells.
Bone Marrow Biopsy
The procedure involves the extraction of a sample of solid bone along with the bone marrow to be examined for cancer cells. It is normally conducted at the same time as a bone marrow aspiration.
Imaging Tests
CT Scan
This is a method that uses multiple X-rays to create pictures of the body. It can reveal the presence of enlarged lymph nodes or organs.
PET Scan
This test makes use of a radioactive sugar to indicate the spots of high activity within the body, which could be cancerous.
MRI
This is a method that uses powerful magnets and radio waves to create images of the body. It can help to illustrate the bone damage that has resulted from multiple myeloma.
Treatments for Blood Cancer
The treatment for blood cancer may vary depending on the type of cancer, the stage of cancer, and the health of the patient.
Chemotherapy
Chemotherapy is a treatment method that uses drugs to kill cancer cells. It is the mainstay of treatment for leukemia, lymphoma, and myeloma.
Radiation Therapy
Radiation therapy uses high-energy X-rays to destroy cancer cells. It is commonly used in lymphoma and some leukemias.
Stem Cell Transplants
This involves replacing diseased bone marrow with healthy stem cells. It is commonly used in leukemia and myeloma.
Targeted Therapy
Targeted therapies focus on specific molecules involved in cancer growth, such as tyrosine kinase inhibitors (TKIs).
Immunotherapy
Immunotherapy helps the immune system fight cancer. CAR T-cell therapy is a major advancement in this field.
Living with Blood Cancers
Chronic Management
Some blood cancers can be managed like chronic diseases such as diabetes or hypertension.
Quality of Life
Modern treatments allow patients to maintain a good quality of life.
Long-term Survival
Many patients now live long-term with proper treatment and monitoring.
Conclusion
It is true that a cure has not been discovered yet for some types of blood cancer; however, treatment results have been greatly improved over the last few decades. Patients can achieve long-term remission and even be considered cured in some cases.
Successful outcomes depend on early diagnosis, correct classification, personalized treatment, and advancements in medicine. Blood cancer is no longer always a fatal diagnosis—it is often treatable and sometimes curable.
