The treatment of bleeding in cancer patients depends on the cause, location, and severity of the bleed. In some cases, supportive care measures, such as transfusions of red blood cells or platelets, may be necessary to manage bleeding. Medications, like tranexamic acid or desmopressin, can be used to reduce bleeding in certain conditions. For localized bleeding, surgical interventions or minimally invasive procedures, such as endoscopic cauterization, may be required to control the bleed. Radiation therapy can also be used to shrink tumors and reduce bleeding in specific cases.
