(OMAHA, Neb.) -- Berkshire Hathaway CEO Warren Buffett announced Tuesday that he has stage I prostate cancer.
Buffett, 81, made his illness known Tuesday in a letter to Berkshire shareholders, assuring them that his diagnosis is not life-threatenening.
"The good news is that I've been told by my doctors that my condition is not remotely life-threatening or even debilitating in any meaningful way," he said in the letter.
Buffett also told shareholders that after receiving his diagnosis last Wednesday, he underwent a CAT scan Thursday and an MRI Tuesday. The tests concluded that there is "no incidence of cancer" anywhere else in his body, Buffett said.
The business magnate says his energy level is "100 percent" and that he feels "great -- as if I were in my normal excellent health," according to the letter.
Buffett said Tuesday that he will begin a two-month treatment of daily radiation in July, which may restrict his travel, but he does not expect his daily routine to change.
A leader entwined with his company’s identity, Buffett said in February he and Berkshire Hathaway’s board have identified a successor. Though Buffett has said the successor does not know he or she has been selected.
Called “The Oracle,” for his business acumen, Buffett has remained silent about his succession plan despite investors who have pushed for more information.
