bone marrow cancer
The most common type of this cancer is multiple myeloma. It starts in the plasma cells. These are white blood cells that make antibodies to protect your body from foreign invaders. Tumours form when your body starts to produce too many plasma cells. This can lead to bone loss and a decreased ability to fight infections.
Leukaemia usually involves white blood cells. The body produces abnormal blood cells that don’t die off as they should. As their numbers grow, they swarm normal white blood cells, red blood cells, and platelets, interfering with their ability to function. Acute leukaemia involves immature blood cells, called blasts, and symptoms can progress quickly. Chronic leukaemia involves more mature blood cells. Symptoms can be mild at first, so you might not know you have it for years. Learn more about the differences between chronic and acute leukaemia. There are many types of leukaemia, including:
- chronic lymphocytic leukaemia, which affects adults
- acute lymphocytic leukaemia affects children and adults
- chronic myelogenous leukaemia, which mainly affects adults
- acute myelogenous leukaemia, which affects children and adults
Lymphoma can start in the lymph nodes or the bone marrow. There are two main types of lymphoma. One is Hodgkin’s lymphoma, also known as Hodgkin’s disease, which starts in specific B lymphocytes. The other type is non-Hodgkin’s lymphoma, which starts in B or T cells. There are also many subtypes. With lymphoma, the lymphocytes grow out of control, forming tumours and making it difficult for your immune system to do its job.
