In the summer of 2004, I felt something in my right breast that didn’t feel normal. They always describe cancer in terms of a pea, right? Well, this was more like several rocks strung together. I thought it was probably scar tissue related to my breast implants. So I let it go—for a long time.

At the time I noticed the lumps I didn’t have insurance, which was a big part of why I didn’t get it checked immediately. I went on the Internet and thought, "It is scar tissue. No big deal." But a year later, I felt another lump right in the center of the breast and something in my right armpit. I saw a surgeon who said, "I’m pretty sure you have breast cancer." After a mammogram, an ultrasound and a biopsy, it was confirmed—stage III.

I opted to get a modified, radical bilateral mastectomy on Aug. 29 at Cedars-Sinai Medical Center in Los Angeles. A surgeon removed both my breasts and 29 lymph nodes.

In a week or so, I start a four- to six-month course of chemotherapy, followed by tamoxifen, a drug designed to prevent a recurrence. My doctor has warned me I may stop having my period and go into early menopause. That’s tough because I haven’t had kids yet.

Being on Survivor has helped in every sense of the word. My doctor told me, "You have beautiful hair, and you’re going to lose it." But Coby Archa, the Texas hairdresser who was in my Survivor tribe, says he’s going to shave my head for me—and shave his too. Survivor taught me there’s an end in sight. As hard as it is, it will be over, and you have to appreciate every day.
