Katie Couric said Wednesday that she'd been diagnosed with breast cancer, and underwent surgery and radiation treatment this summer to treat the tumor.

She was diagnosed on the first day of summer and wrote that she had her final radiation treatment on Tuesday.

"My left breast does feel like I've been sunbathing topless, but other than that, I've felt fine," she wrote.

Couric's first husband, Jay Monahan died of colon cancer in 1998 and her sister Emily was 54 when she died of pancreatic cancer in 2001. She wrote, "why would I be spared? My reaction went from 'why me?' to 'why not me?'"

She underwent a lumpectomy on July 14 and began radiation treatment on Sept. 7. "I felt sick and the room started to spin," she said.
