After Angelina Jolie’s Mastectomy News, What You Should Know About BRCA Gene

Posted byBy ABS Contributor | Published on: CommentsComments (0)

With the recent news that Angelina Jolie had opted for a double mastectomy to reduce her risk of contracting breast cancer, there’s been a lot of attention focused on the breast cancer susceptibility gene (BRCA) that caused Jolie to take such a drastic action.

This gene is responsible for approximately 5 percent of breast cancer cases in America. Though the overwhelming majority of cases diagnosed are not associated with BRCA1 or BRCA2, the risk is still present. Before you go to your doctor to request a BRCA genetic test, here a few things to know:

Cancer is disease resulting from a gene that has gotten out of control. Genes tell the cells what to do, specifically what type of protein to create. The breast cancer susceptibility genes (BRCA1 & BRCA2) are codes for proteins that help to maintain the stability of DNA (deoxyribonucleic acid).

BRCA1 is associated with increased risk of breast, cervical, uterine, colon, and pancreatic cancers. BRCA2 is associated with increased risk of ovarian, pancreatic, bile duct, gallbladder, and stomach cancers.

Men can also be affected with male breast cancer from these genes. Additionally, BRCA1 in men is associated with increased risk of testicular cancer, and BRCA2 is associated with increased risk of prostate cancer.

Not everyone needs BRCA genetic testing. Only people who have a strong family history for breast and ovarian cancer should be tested for BRCA. If you have a sister, mother, or aunt who was diagnosed with breast or ovarian cancer before menopause or a brother, father or uncle who was diagnosed with breast cancer, then discuss this with your physician. Remember, an association is not a definite diagnosis, so speak with your doctor to determine risk factors prior to genetic testing. If you do not know your family history, then it may be reasonable to have the BRCA test.

Routine breast self-exam and mammography remain the best ways to screen for breast cancer. Make it your mission to regularly schedule your annual mammogram starting at age 40, or earlier if you have a family history; remind your sisters, friends, and family to do the same. Though Breast Cancer Awareness Month isn’t until October, health awareness is necessary year round and can be the difference between life and death.

Be well.

Democracy needs journalism it can trust.

This election season, the stakes are higher than usual — and so is the pressure on newsrooms to soften their coverage, stay quiet, or just disappear. Independent reporting, the kind that answers to readers instead of advertisers or political pressure, matters more in a moment like this, not less.

For over 14 years, Atlanta Black Star has stayed independent and reader-funded. We have no corporate owner and no shareholders telling us what to cover or how to cover it. That independence is also our biggest vulnerability: nothing protects it except readers choosing to fund it directly.

Newspaper ad revenue has fallen more than 80% since 2005, and local newsrooms are closing at a rate of roughly two a week nationwide. When outlets go under in a moment like this, it's rarely the independent, reader-funded ones that get to stick around.

We know a request for support isn't why you came here. But without readers choosing to fund this work directly, the depth of reporting we can do at home and abroad shrinks along with everyone else's. If you're not in a position to give, that doesn't change how much we value you as a reader.

If you are able to, a recurring contribution does more for us than a single one-time gift, because it lets us plan the next investigation instead of just the next invoice. It takes about 30 seconds, no long form, no account. Thank you for continuing to support independent journalism and freedom of the press.
