The Day I Was Told About My BRCA Gene
Knowledge gives you more control over your health
Thoughts on the Breast Cancer Gene Test
These days, it seems everyone is talking about gene testing, and not just for medical reasons. Foods have become either genetically modified or not; TV commercials and at-home kits encourage us to find out who we are, even down to the microscopic details of our ancestors’ genetic makeup.
Women with breast cancer in their family histories relate to gene tests a little more seriously, though. Many times, a mutation of either the BRCA1 or BRCA2 genes can be the cause of that family history, or at the very least, an indicator of higher risk.
BRCA basics: What are the options?
You can’t choose the genes you inherit — you get what you get. But there are things you can do once you know you have a defective BR(east) CA(ncer) gene:
- Monitor more closely and more often, via mammogram, ultrasound or MRI in the hopes of catching cancer early and treating it successfully;
- Take chemoprevention medications, which have been found to reduce risk in some healthy but high-risk women;
- Surgically remove the breasts in what’s called prophylactic or preventive mastectomy.
Decision-making: How the breast cancer gene test can benefit you
“The day – or week, really – I found out about my BRCA genes is really vivid in my memory,” says Yocheved K., a breast cancer survivor in New York. She was referred to genetic counseling after a breast biopsy and tumour discovery, because of her family history and her heritage being of Ashkenazi (Eastern European) Jewish descent. This population often experiences higher risk for a number of health issues, including the BRCA mutations.
“After genetic counselling and the test, I got a call. ‘We have good news, the test is negative for BRCA1.’ I was so happy. [I thought] I wouldn’t have to bother my siblings with this, or my kids… Then a week later, they called again: ‘We’re sorry, you tested positive for the BRCA2 mutation.’”
It was an emotional roller coaster, she admits, but ultimately it informed her treatment decisions. Yocheved opted to have a double mastectomy (although she only had a tumor in one breast) as a preventive measure. “After the test result, the double mastectomy was a no-brainer,” she adds.
Other women make different choices, but the common key is having the information.
Susan C. is a previvor – someone who chose preventive mastectomy prior to any evidence of cancer. She knew what she would choose almost immediately, when given her positive BRCA1 test result. With an 87% chance of breast cancer and 44% chance of ovarian cancer, “The last thing in the world I wanted to do was remove perfectly healthy body parts… except: The VERY last thing I wanted to do was tell my kids I had cancer. So if I had to do the second-to-last thing, sign me up all day long.”
She has no regrets, despite experiencing some of the unpleasant effects of surgically induced menopause after her accompanying oophorectomy.
“I think it’s important for women to know there is no wrong answer. And if you do the testing, and you feel comfortable, share those results with your immediate and extended family. I have no fewer than 28 female first cousins, and several of them decided to be tested, along with their daughters.”
Not every person with a genetic mutation will get breast or ovarian cancer in their lifetime, of course. And it’s sometimes difficult to think about potential health problems like cancer – some might say ignorance is bliss. But armed with information from a breast cancer gene test, you can truly be in better control of your health, make informed decisions and look forward to a long, healthy life.
