MTV reality star Diem Brown has decided to undergo another round of fertility treatments in order to harvest more eggs before she surgically removes her ovary as part of her cancer treatment, People.com reported.

Brown, who was diagnosed with ovarian cancer at the age of 22, had one ovary and several lymph nodes removed before she starred in Real World/Road Rules Challenge. She participated in the network's The Challenge: Battle of the Exes in 2011.

Now, at the age of 30, the cancer has returned, and doctors need to remove the last part of her remaining ovary.

She told People.com that she knows her decision to delay surgery will make other people judge her, but she won't have any regret.

"This isn't my first rodeo, and regret can become your worst enemy," Brown wrote in her blog on People.com. "I've already been through the long and challenging months of chemo six years ago, and I remember how depressed I was during certain parts of my treatment."
