Overview
Blood cancer impacts blood cells and the bone marrow, the spongy tissue inside bones, which is the source of blood production. This type of cancer alters the behaviour and functioning of blood cells, causing them to multiply rapidly and disrupt normal bodily activities.
There are four main types of blood cells:
- White Blood Cells (WBCs): Play an important role in fighting infections and are an integral part of the immune system.
- Red Blood Cells (RBCs): Carry oxygen to tissues and organs and transport carbon dioxide to the lungs for exhalation.
- Platelets: Aid in blood clotting, which is crucial for healing when injured.
Types of Blood Cancer
There are mainly three types of blood cancer, further divided into subtypes. They are as follows:
1. Leukemia
People with leukemia make many WBCs that cannot fight infections. There are four major subtypes:
- Acute Lymphocytic Leukemia (ALL): Affects lymphocytes, leading to a lack of healthy cells. Common in children.
- Acute Myeloid Leukemia (AML): Begins in myeloid cells and lowers the number of healthy blood cells.
- Chronic Lymphocytic Leukemia (CLL): Slow-growing and mainly affects older adults.
- Chronic Myeloid Leukemia (CML): Starts in myeloid cells; abnormal cells grow slowly and are more common in men.
2. Lymphoma
Cancer of the lymph system including lymph nodes, spleen, and thymus gland. Two main types:
- Hodgkin’s Lymphoma: Starts in B lymphocytes (B cells) that produce antibodies to fight germs.
- Non-Hodgkin’s Lymphoma: Starts in T cells or B cells.
3. Myeloma
A cancer of plasma cells, a type of WBC that makes antibodies. It can damage bones, crowd out healthy cells, and produce ineffective antibodies.
Causes of Blood Cancer
- Smoking
- Exposure to radiation or harmful chemicals
- Family history of leukemia
- Genetic disorders such as Down syndrome
Symptoms of Blood Cancer
Blood cancer can manifest through a variety of symptoms, such as:
- Persistent fatigue
- Unintended weight loss
- Anemia
- Night sweats
- Headaches
- Fever and chills
- Nausea
- Joint pain
- Shortness of breath
- Swollen lymph nodes
- Frequent infections
Prevention of Blood Cancer
- Avoid exposure to radiation and harmful chemicals.
- Quit smoking.
- Maintain a balanced, healthy diet.
- Exercise regularly and stay active.
Diagnosis of Blood Cancer
Blood cancer can be diagnosed through several tests and procedures, including:
- Complete Blood Count (CBC): Measures types and quantities of blood cells to identify abnormalities.
- Bone Marrow Biopsy: Examines bone marrow samples to assess cancer presence and stage.
- Lymph Node Biopsy: Evaluates lymph nodes for cancer type and spread.
- Spinal Tap: Tests cerebrospinal fluid for signs of cancer spread to the spinal cord.
- Karyotype Test: Maps chromosomes to detect genetic abnormalities linked to cancer.
Treatment of Blood Cancer
Blood cancer can be treated through various methods, including:
- Chemotherapy: Uses drugs to destroy rapidly growing cancer cells and prevent further spread.
- Radiotherapy: Uses high-energy radiation to damage cancer cell DNA and inhibit growth.
- Targeted Therapy: Focuses on specific genes, proteins, or blood vessels that help cancer grow.
- Immunotherapy: Strengthens the immune system to recognize and fight cancer cells.
- Stem Cell Transplantation: Replaces damaged bone marrow with healthy blood-forming stem cells.
Takeaway
Blood cancer can significantly impact one’s health, but early detection and modern treatment options greatly improve recovery chances.
Staying informed about causes, symptoms, and prevention methods empowers individuals to take proactive steps toward better health and timely treatment.
