Potential Side Effects from Radiation for Kaposi Sarcoma

Doctors often use small doses of radiation to treat Kaposi sarcoma (KS). When the treatment is done just in one area of the skin, the side effects are mild.

These are some possible side effects from radiation for KS:

  • Mild skin irritation

  • Nausea

  • Vomiting

  • Fatigue

You may have pain from the lesion. This pain should go away within two weeks of the completion of radiation therapy. Healing from radiation side effects will be hastened in patients with low HIV viral load and improved CD4 cell counts through highly active antiretroviral therapy (HAART).  Radiation can sometimes worsen the symptoms of chemotherapy.
