Deena Kastor, America's top distance runner and an Olympic bronze medalist in the marathon, has revealed that she has skin cancer. On her website, Kastor reports that she has three spots on her body that have been diagnosed with various forms of skin cancer.

"I have 25 external stitches for Basal Cell Carcinoma and early stages of melanoma," writes Kastor on her website (www.deenakastor.com). "I also have six internal stitches to tie off blood vessels the doctor cut through because the cancer runs deep."

She is awaiting biopsy results that will--hopefully--reveal that all the cancer was removed, but she is postponing her training for the outdoor track season. "In oncology and dermatology, they call what I am hoping for as clear margins," writes Kastor.

Kastor, who lives in Mammouth Lakes, California, said that she gets checked every three months for skin cancer and uses sunscreen everytime she goes outside. "Only once in the past six years have I walked outside the doctor's office without some form of cancer being biopsied or removed," writes Kastor.

The 34-year-old Arkansas graduate holds American road records for the marathon, half-marathon, 15-K, 12-K, 10-K and 5-K as well as 10,000 meters on the track.
