Co-founder Microsoft has cancer again

seattle - Co-founder of Microsoft Paul Allen is seriously ill again. He is being treated for lymphoma, he said on Monday.

All suffers from Non-Hodgkin's lymphoma, the same disease that was also diagnosed in 2009. In a short statement, he says that he recently learned that the disease has returned. 'A lot has happened in medicine since I overcame this disease in 2009,' writes Allen, who says he and the doctors are optimistic about the treatments he gets.

Allen founded the American software company Microsoft in 1975 with Bill Gates. He left Microsoft in 1983.
