Certain cancer treatments reduce the number of blood cells patients have in their bodies. A reduced supply of red blood cells can cause anemia and a feeling of weakness. A reduction of platelets may increase the risk for bleeding. Our patients depend on volunteers in the community to donate blood and platelets to replenish their blood supply and begin to feel better. We thank you for considering making a donation.
