Introduction
Blood, a vital fluid in our bodies, circulates essential materials for our functions. It comprises three main elements: erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets).

Understanding Blood Cancer
Blood cancer, also known as hematologic cancer, arises when cancerous growth hampers blood functions. This cancer can be triggered by factors such as gene mutations, exposure to radiation, harmful chemicals in hair dyes, and lifestyle choices like smoking, alcohol, and drug abuse.
Types of Blood Cancer
Leukemia
- Acute Myeloid Leukemia (AML): Begins in the bone marrow, characterized by an excess of immature white blood cells, commonly found in adults.
- Acute Lymphoblastic Leukemia (ALL): Originates from a DNA mutation in stem cells, leading to rapid production of immature white blood cells, primarily affecting children.
- Chronic Myeloid Leukemia (CML): Starts in blood-forming cells of the bone marrow, with abnormal white blood cells that live longer than usual.
- Chronic Lymphocytic Leukemia (CLL): Develops in the lymphocytes of the bone marrow, with abnormal cells that grow rapidly and often lack early symptoms.

Lymphoma
- Non-Hodgkin Lymphoma: Begins in the lymphatic system with abnormal growth of lymphocytes forming tumors.
- Hodgkin Lymphoma: Characterized by excessive lymphocytes causing swollen lymph nodes and tumor development.
Myeloma
A tumor in plasma cells that hampers antibody production, weakening the immune system and increasing susceptibility to infections.
Symptoms of Blood Cancer
- Leukemia: Fever, chills, frequent infections, fatigue, easy bruising or bleeding, swollen lymph nodes, and bone pain.
- Lymphoma: Swelling of lymph nodes, recurring fatigue, fever, and itchy skin.
- Myeloma: Bone pain, nausea, loss of appetite, confusion, frequent infections, and excessive thirst.
Causes of Blood Cancer Blood cancer originates from DNA mutations in blood cells, influenced by genetic factors, infections, lifestyle habits, and environmental exposures, including harsh beauty products and radiation.
Treatment Options
- Chemotherapy: Uses cytotoxic chemicals to stop the growth of cancer cells, requiring regular hospital visits.
- Stem Cell Transplantation: Infuses healthy blood-forming stem cells into the patient's body to replace the diseased cells.
- Radiation Therapy: Employs X-rays to destroy cancerous tumors.

Comparison Table of Blood Cancer Types
| Type | Description | Common Age Group |
|---|---|---|
| Acute Myeloid Leukemia | Excess immature WBCs in bone marrow, spreading to blood | Adults |
| Acute Lymphoblastic Leukemia | Caused by DNA mutations, rapid WBC production | Children |
| Chronic Myeloid Leukemia | Genetic changes in myeloid cells, abnormal WBCs live longer | Adults |
| Chronic Lymphocytic Leukemia | Abnormal lymphocyte growth, slow symptom onset | Adults |
| Non-Hodgkin Lymphoma | Abnormal lymphocyte growth, forms tumors | Adults |
| Hodgkin Lymphoma | Excessive lymphocytes, swollen lymph nodes | Adults |
| Myeloma | Tumors in plasma cells, impairs antibody production | Adults |
