NEW YORK (CNNMoney) -- Iconic investor Warren Buffett announced Wednesday that he has been diagnosed with stage I prostate cancer in a letter to shareholders of his firm Berkshire Hathaway.
Buffett, 81, said his "condition is not remotely life-threatening or even debilitating in any meaningful way," and that tests didn't reveal incidence of cancer anywhere else in his body.
Buffett also said he will undergo daily radiation for two months beginning in mid-July. While the treatment will restrict him from traveling during the period, Buffett said his daily routine will not otherwise change.
"I feel great -- as if I were in my normal excellent health -- and my energy level is 100%," wrote Buffett. "I will let shareholders know immediate should my health situation change. Eventually, of course, it will; but I believe that day is a long way off."
Doctors discovered the cancer after Buffett's prostate-specific antigen levels jumped and warranted a biopsy. Buffett received his diagnosis last Wednesday.
Share of Berkshire Hathaway slipped 1.5% in after-hours trading Tuesday.
