Diem Brown, 'Challenge' Star, Dies After Brave Cancer Battle

Diem Brown Challengestar

We're very saddened to report a big loss in the MTV family.

Diem Brown, whose tenacity shined bright throughout her years on ' The Challenge ' and embodied an unparalleled strength during numerous battles with cancer, has passed away,

But in June 2012, six years into remission, Diem faced another hurdle: Traces of the disease had returned . She candidly opened up about her second battle with cancer, even courageously documenting her hair loss and revealing plans to freeze her embryos in order to fulfill her dream of becoming a mother.

Diem prevailed again, sharing her positive prognosis in February 2013, and not long after undergoing chemotherapy, she returned to the 'Challenge' circuit on ' Rivals II ,' where she and her partner Aneesa finished strong in fourth place.

Diem faced her toughest hardship in August, when she was diagnosed with cancer for a third time. But through it all, she showed her resilience and vowed to never give up , even during her final days.

'You can count me out all you want,' she recently told People . 'But I'm not out. I'm fighting. I want to be here.'

Please offer your condolences to Diem's family and friends in the comments below.
