Martina Navratilova has been diagnosed with throat cancer as well as breast cancer.
The 18-time Grand Slam singles champion, who was diagnosed with breast cancer in 2010, will begin treatment later this month in New York.
Navratilova, 66, said both cancers were discovered at an early stage.
“The double whammy is serious, but it’s fixable, and I’m hoping for the best,” she said. “It’ll stink for a while, but I’ll fight with everything I’ve got.”
Navratilova discovered an enlarged lymph node in her neck during the WTA Finals in Fort Worth, Texas, in November.
A subsequent biopsy revealed that the patient had stage one throat cancer.
During the tests, a lump in her breast was discovered, which was later diagnosed as an unrelated cancer.
Navratilova was scheduled to cover the Australian Open from the Tennis Channel studio this month, but will instead make a few remote appearances.
After being diagnosed with cancer in 2010, the nine-time Wimbledon singles champion said she felt “helpless,” but decided to go public with the news to help other women in similar situations.
