A reality TV star who has been in a battle with cancer for years was hospitalized as the fight took a turn for the worse. Us magazine reports that Diem Brown, known for her appearances on MTV’s “Real World/Road Rules Challenge,” took to Twitter and Instagram to reach out to her fans.

“I NEED PRAyErs and advice my doctors are seemingly giving up but I won’t & can’t rollover,” Brown tweeted. “Whatever option I have to LIVE I’m grabbing!”

Brown, 32, has reportedly been battling ovarian cancer since 2006, and has had a number of relapses. She collapsed on the set in Panama back in August during filming of her eighth “Challenge” competition, after which she was reportedly diagnosed with colon cancer.

In a recent interview with Us she said: “I’ll beat cancer again. I’m a warrior.”

“Brown was scheduled to receive her second of five chemotherapy treatments next Tuesday, Nov. 18. The MedGift charity founder was staying positive, hoping to ‘shrink the tumors’ with the prescribed drug cocktail,” Us reports. “The stunning star was also seeking treatment through positive thinking. Brown’s sister Megan Brown told Us, ‘In conjunction with chemo, Diem’s doctor suggested imagining herself healthy and cancer-free.'”
