Bone marrow suppression

The side effects of chemotherapy depend on the type of chemotherapy and the amount given. Anticipating and managing side effects can help to minimize them and provide the best possible experience for the person receiving chemotherapy.

What is bone marrow suppression?

As each person’s individual medical profile and diagnosis is different, so is his or her reaction to treatment. Side effects may be severe, mild or absent. Be sure to discuss with your cancer care team any/all possible side effects of treatment before the treatment begins.

Nearly all chemotherapy agents suppress the bone marrow, which causes a reduction in the number of blood cells. The timing of this reduction varies according to which agents are used for your treatment. Red blood cells carry oxygen, white blood cells fight infection, and platelets help to control bleeding and bruising. Thus, the risks for anemia, fatigue, infection bleeding and bruising are increased with bone marrow suppression.
