Billionaire investor Warren Buffett has told his company's shareholders in an open letter that he has been diagnosed with early-stage prostate cancer.

The 81-year-old CEO of Berkshire Hathaway Inc. said his condition is "not remotely life-threatening" or debilitating. He said he and his doctors have decided on a two-month treatment plan that is to begin in mid-July.

Buffett said he was diagnosed April 11 and has received tests including a CAT scan, a bone scan and an MRI.

He says he feels great and that his energy level is 100 percent.
