( CNN ) -- Cycling legend Lance Armstrong -- a survivor of testicular cancer -- and girlfriend Anna Hansen are expecting a baby , CNN learned on Tuesday through his charitable organization . Cyclist Lance Armstrong has announced he will come out of retirement and race once again in the Tour de France . The baby is due in June . Armstrong was diagnosed in 1996 with testicular cancer that had spread to his brain , lungs and abdomen . He underwent treatment for the disease and was able to return to cycling , eventually winning seven consecutive Tour de France 's . The harsh chemotherapy left him unable to have children , although he and then-wife Kristin Richards had three children using sperm the cyclist had donated before the treatment . Armstrong and Hansen , however , are expecting without the use of any artificial fertilization process . `` This is a hopeful thing for testicular cancer survivors , '' CNN medical correspondent Dr. Sanjay Gupta said . `` It means his body healed from the chemotherapy and surgery . '' Armstrong retired from cycling after his seventh Tour de France win in 2005 , and focused his energy on the Lance Armstrong Foundation ( livestrong.org ) , which supports people affected by cancer . Armstrong founded the organization in 1997 . The 37-year-old Texan announced in September that he was launching a comeback with the goal of winning the Tour de France in 2009 . `` After talking with my children , my family and my closest friends , I have decided to return to professional cycling in order to raise awareness of the global cancer burden , '' he wrote on LiveStrong 's Web site . He is training for several races leading up to the Tour de France , including Australia 's Tour Down Under and the Giro d'Italia .
Three - times Tour de France champion Armstrong is a survivor of testicular cancer . The year - old Texan already has three children from his marriage . ` ` This is a hopeful time for all testicular cancer survivors , '' says Sanjay Gupta .
