Bone marrow cancer is a form of cancer that starts in the spongy tissue -- the marrow -- inside your bones. Marrow’s main job is to make blood cells. There are many different types of bone marrow cancer. Here are a few:

Multiple Myeloma

Lymphomas

Leukemia

Childhood Leukemia

Treatments

Treatment depends on the type of cancer you have, how far it has spread, and other factors. The main treatments are:

Chemotherapy (Chemo)

Immunotherapy

Targeted therapy drugs

Radiation

Stem cell transplant. During chemo, cancerous bone marrow cells are killed off. In high-dose chemo, the stem cells that form blood in your bone marrow are also destroyed. A stem cell transplant -- also called a bone marrow transplant -- creates more of the cells that grow in your marrow. After chemo or radiation, you’ll get them through an IV, an injection into your veins.
