When MTV reality star Diem Brown was diagnosed with ovarian cancer at 23, she had to have one ovary, several lymph nodes and part of her fallopian tube removed – but she didn't let that stop her from traveling to Australia to participate in the Real World/Road Rules Challenge
one month later.
Now she'll have her strength tested again.
Brown, who founded MedGift
, a gift registry for those suffering any illness, was recently diagnosed with ovarian cancer yet again.
"Didn't think ovarian cancer could come back," Brown, 30, Tweeted last week
. "Please get internal ultrasounds/year."
In May, she Tweeted that "pain is an indicator telling u something is wrong," and that she needed to have a "large cyst" removed because of elevated CA125 levels. Luckily, her doctor was able to leave in 30 percent of her remaining ovary so that she could harvest eggs.
"Want the baby hope," she wrote. "On a mission 2try&find ANY fertility doctor that will allow me2 freeze ovarian tissue even w/ovarian cancer."
She found him. Brown is working with NYU doctor Jamie Grifo, and added that she's getting shots to "get some eggs" before her second ovary is removed entirely.
"I know I will be fine," she writes. "I beat Cancer once & I'm gonna do it again! I know God has a reason for every speed bump in life & I'm ready."
