Update: Diem Brown died on Friday, Nov. 14, at the age of 32 after a long battle with cancer. The reality-TV star announced in August that doctors found cancer in her stomach and colon. The cancer had spread to her liver and lymph nodes.

The original story follows below.

MTV “The Challenge” star Diem Brown has turned to her fans for support following her most recent cancer diagnosis and hospitalization. The longtime reality star and two-time cancer survivor has taken to social media to ask her fans for their help in the midst of her battle with colon cancer following her claims that her doctors have given up.

“I NEED PRAyERS and advice my doctors are seemingly giving up but I won’t & can’t rollover. Whatever options I have to LIVE I’m grabbing!” Diem, 33, said on Twitter Tuesday evening.

“Need tons of prayers, advice, support and outreach. I’m not taking no for an answer,” Diem followed up on Instagram, directing her fans to reach out to her friend, E! News correspondent Alicia Quarles, for medical advice. “Contact her. We know there is hope and help. We need you,” she said.

Quarles responded to Diem’s request by posting an image of the longtime MTV star sharing a meal with friends. “Toasting the strongest girl we know: #diemstrong #friendsarefamily," Quarles captioned the photo.

Diem’s former MTV co-star and ex-boyfriend Chris "CT" Tamburello has also shared his support online. For the past two consecutive weeks, CT has claimed Diem as his “WCW” (Women Crush Wednesday) on Twitter and Instagram. The reality star also famously visited Diem in the hospital in September.

According to a timeline from People.com, Diem, a staple on the MTV program “The Challenge,” battled ovarian cancer prior to her starring role on “Real World/Road Rules Challenge: Fresh Meat" in 2006. During a later appearance on the competition series, she met and began her on-again, off-again romance with CT. In 2012, her ovarian cancer returned and doctors were forced to remove her ovaries. In Feb. 2013 she announced she was cancer-free after a long bout of chemotherapy. After getting a clean bill of health, she went on to star on MTV's "The Challenge (Rivals II)" in 2013.

While filming a reality series abroad in August, Diem was airlifted to New York after collapsing on set and was rushed in for immediate surgery after being diagnosed with colon cancer. After undergoing several surgeries, including a hysterectomy, Diem announced last month that her cancer had spread to her stomach, liver and lymph nodes. Her next chemotherapy treatment is expected to occur Nov. 18.

“It’s my personal perspective that you live as hard and as vigorously as you can,” Diem told People last month. “My goals are something I believe in, because I believe I’m going to make it. I’m going to have a family and get married and the whole American, 2 1/2 kids white-picked-fence dream …”
