Gynecologic cancers originate in the female reproductive organs, including the cervix, ovaries, fallopian tubes, uterus, vagina and vulva. Radiation therapy is used to treat gynecologic cancers painlessly and non invasively. External beam radiation therapy (EBRT) is an effective treatment for gynecological cancers, working within cancer cells to damage their ability to multiply. During treatment, high-energy X-rays are delivered to the cancer cells with a linear accelerator (LINAC). Treatments are delivered daily Monday through Friday. Each treatment takes about 15 to 30 minutes. The treatment process is painless, safe and will not burn or hurt you. Side effects are usually minimal, and most patients return to routine activities immediately after each treatment. Several factors determine candidacy for radiation therapy treatment including the stage of the cancer, potential side effects, age and overall health. Sometimes a combination of treatments is the best plan for treating gynecologic cancers.
