Long term complications of chemotherapy or radiation therapy include:
Bone marrow diseases
Heart disease
Inability to have children (infertility)
Lung problems
Other cancers
Thyroid problems
Chemotherapy can cause low blood cell counts, which can lead to an increased risk of bleeding, infection, and anemia. To minimize bleeding, apply ice and pressure to any external bleeding. Use a soft toothbrush and electric razor for personal hygiene.
Infection should always be taken seriously during cancer treatment. Contact your doctor immediately if you develop fever or other signs of infection. Planning daily activities with scheduled rest periods may help prevent fatigue associated with anemia.
