Blood Cancer

Leukemia is a type of blood cancer that starts in the bone marrow, where blood cells are produced.
It leads to uncontrolled growth of abnormal white blood cells, which crowd out healthy blood cells.
Common symptoms include fatigue, frequent infections, fever, bleeding, and weight loss.
Leukemia can be acute (fast-growing) or chronic (slow-growing), affecting children and adults differently.
Treatment includes chemotherapy, targeted therapy, radiation, and bone marrow transplant.
