Billionaire Seattle Seahawks owner and Microsoft co-founder, Paul Allen, says cancer he was treated for in 2009 has returned.
Allen said on Twitter, on Monday, that he recently learned of the non-Hodgkin’s lymphoma and plans to fight it aggressively.


He says there have been advances in medicine since he overcame the disease nearly a decade ago, and that he and his doctors are optimistic that he will see good results from the latest therapies.
