Leukemia Overview.

Leukemia is a cancer of the body's blood-forming tissues, including the bone marrow and the lymphatic system. It is characterized by the rapid, abnormal production of white blood cells that don't function properly.

Types

Leukemia is classified by:

• Speed of progression: Acute (fast-growing, immature cells, requires urgent treatment) or Chronic (slow-growing, more mature cells).

• Type of cell affected: Lymphocytic (or lymphoblastic) or Myeloid (or myelogenous).

The four main types are:

• Acute Lymphoblastic Leukemia (ALL)

• Acute Myeloid Leukemia (AML)

• Chronic Lymphocytic Leukemia (CLL)

• Chronic Myeloid Leukemia (CML)

Causes, Risk Factors, and Prevention.

The exact cause is often unknown, but it involves genetic mutations in the blood cell DNA.

• Key Risk Factors include exposure to high levels of ionizing radiation, certain industrial chemicals like benzene, previous chemotherapy or radiation therapy for other cancers, some genetic syndromes (like Down Syndrome), and smoking.

• Prevention generally focuses on avoiding known environmental risk factors like smoking and benzene exposure.

Signs and Symptoms:

Symptoms are often vague and can resemble the flu:

Persistent fatigue and weakness (due to anemia—low red blood cells).

Frequent or severe infections and fever (due to non-functional white blood cells).

Easy bruising and bleeding (due to low platelets).

Tiny red spots on the skin (petechiae).

Bone pain or tenderness.

Swelling of the lymph nodes, liver, or spleen (splenomegaly).

Treatment Options:

Treatment depends on the type, stage, and patient's overall health.

Chemotherapy is the main form of treatment for most types.

• Targeted Therapy drugs attack specific abnormalities (e.g., using Tyrosine Kinase Inhibitors for CML, which has the Philadelphia chromosome).

• Immunotherapy (including CAR T-cell therapy) boosts the immune system to fight cancer.

• Stem Cell Transplant (or Bone Marrow Transplant) replaces diseased bone marrow with healthy blood-forming stem cells.

• Radiation Therapy is sometimes used to destroy leukemia cells or prepare for a transplant.

• Watchful Waiting may be an option for some slow-growing chronic leukemias (like early-stage CLL).
