The billionaire US Investor Warren Buffett has completed the treatment for his prostate cancer. "Today I had my 44th and last day of radiation", the 82-Jährige executives from newspapers belonging to him said as the paper "The Omaha World-Herald" reported on its website on Friday.

He will feel the side effects a few weeks - but he was "so happy" to be able to say that it was "over". "Today is a great day for me," Buffett added. The disease was diagnosed in April at an early stage.

Buffett is the Chief and the investment company Berkshire Hathaway, which is part of the Omaha World-Herald company. He comes from the city of Omaha in Nebraska, United States.

The U.S. magazine "Forbes" leads Buffett with assets of $44 billion (EUR 33.7 billion) as the third richest man in the world.
