If you've been diagnosed with seminoma, a common form of testicular cancer, it's very likely you'll make a full recovery. This type of cancer, which originates in germ cells in the testicles (also called pure, or classical, seminoma) usually responds well to radiation therapy.  Coupled with surgery and chemotherapy, this has helped make survival rates for patients with Stages I and II seminoma nearly 100 percent. 

Part of that success is derived from Yale Medicine’s commitment to advancing the field, says James Yu, MD, MHS, associate professor of therapeutic radiology at Yale School of Medicine and director of Yale Medicine's Prostate & Genitourinary Radiotherapy Section. “We're always looking for even the smallest improvements.”

In general, patients with early-stage seminoma, who have undergone proper surgical removal of their testicular cancer (through an operation called a radical orchiectomy), may be good candidates for radiation therapy.

Seminomas are sensitive to radiation, so the treatment is usually successful. In contrast, experience and research have shown that non-seminoma cancers respond better to chemotherapy than to radiation; they’re just not sensitive enough to the radiation to be reliably eradicated.
