Leukaemia is a cancer of blood cells caused by rise in the number of white blood cells (abnormal production of leukocytes) in the body. There are three types of cells: white blood cells that fight infection, red blood cells which carry oxygen and platelets that help blood to clot. When you have leukaemia your body starts making more white blood cells than red cells which forms bone marrow.
Leukemia can occur in either type of two main white blood cells: lymphoid cells and myeloid cells.
When most of the abnormal blood cells cannot function properly leads to acute leukaemia. Chronic leukaemia occurs when there are few immature cells other than the normal cells that functions properly which means it gets bad slowly than the acute leukaemia.
It can be detected by excessive sweating, fatigue, bone pain and tenderness, painless swollen lymph nodes, liver enlargement, red spots on the skin, frequent infections. Leuakaemia can also affect other organs that have been infiltered by blood cells e.g. lungs, heart, gastrointestinal tract, kidneys, and testes. Blood tests, biopsy, and imaging test can help in diagnosing the cancer. Hematologist –oncologist treats this type of cancer.
