Low platelet counts, known as thrombocytopenia, can be a concern in cancer patients for several reasons: - Chemotherapy Side Effects: Many chemotherapy drugs can suppress bone marrow function, leading to reduced platelet production. - Bone Marrow Involvement: Certain cancers, like leukemias and lymphomas, directly affect the bone marrow's ability to produce platelets. - Increased Risk of Bleeding: Low platelet counts increase the risk of bleeding and bruising, which can complicate surgical procedures and other treatments.
