What is systemic radiation therapy for cancer?

Radiation treatment uses radioactive material to kill cancer cells or to keep them from growing. In systemic treatment, the material is given by mouth or injection. It travels in the blood throughout the body and targets cancer cells. Then the radiation leaves the body through body fluids.

Systemic treatment is painless. But it can cause some side effects. These include fatigue, nausea, vomiting, and diarrhea. Most side effects usually go away after the treatment ends. But you may feel very tired for 4 to 6 weeks afterward. Your doctor can help treat the side effects. The treatment may also lower the number of certain blood cells in your body. Your doctor will watch your blood cell counts.

Before and during treatment, get plenty of rest. Eat healthy foods to keep your strength up. Your doctor will tell you what activities you can do during treatment.
