Anemia is a decrease in the number of red blood cells (RBC's) or hemoglobin, resulting in a lower ability for the blood to carry oxygen to body tissues.
Anemia has many causes. Common causes of anemia in lung cancer include:
- Bone marrow suppression (myelosuppression) - due to chemotherapy
- Bleeding - due to surgery, or from complications of the cancer
- The cancer itself - anemia is common with many chronic diseases, due to the disease itself, or secondary to nutritional deficiencies brought on by the disease
