I Was About to Have a Double Mastectomy—Then a Genetic Test Changed My Life

[brightcove:5522487361001 default]

I have a lot of breast cancer in my family. I have an older sister who was diagnosed at stage 3 when she was 39, a grandmother who had stage 4 in her 30s, and an aunt who was diagnosed after menopause.

Last summer, when I was 48, I finally had a mammogram after not getting around to it for a few years, and I got a suspicious result. I had a second mammogram and a biopsy. The doctors found DCIS, or cancer/dcis-breast-cancer”>ductal carcinoma in situ. DCIS is really pre-cancerous cells, and the hard thing is that sometimes it turns into invasive cancer and sometimes it doesn’t. Doctors tend to treat it all the same pretty aggressively. Given my family history and my diagnosis, my surgeon thought it was likely my DCIS could turn into invasive cancer. He recommended that I get a double mastectomy.

My sister, facing a second cancer diagnosis, decided to undergo genetic testing. She found out she’s a carrier of a genetic mutation which increases breast cancer odds called CHEK2. (A CHEK2 mutation doubles breast cancer risk, according to the American Cancer Society.) That was another piece of data for my doctor, who assumed I was probably a carrier too.

“Hold on,” I said, “let me get tested myself to confirm that.” My doctor ordered a breast cancer gene test from a company called Color. [Note: Katie Stanton, Color's chief marketing officer, is on the board of directors of Time Inc., the parent company of Health.

When she called me after she got the results back, she was kind of speechless. She couldn’t believe it, given my DCIS diagnosis and my family history, but I wasn’t a carrier for CHEK2 or BRCA mutations, which also increase breast cancer risk.

The results totally changed how I chose to treat my DCIS. Without the test, I would have gotten a double mastectomy, taken tamoxifen for 10 years, and had radiation. Testing enabled me to decide on less treatment, which felt safe and right for me. Unfortunately, there’s a narrative that more testing means more treatment, but my situation was exactly the opposite. I chose to treat my DCIS with just a lumpectomy. It was a complicated decision, but a minimally invasive course of treatment was the right choice for me.

I’m one of five kids, and three are carriers of CHEK2. One brother and I are not. It’s weird to know my sister has suffered so much given her genetic predisposition, and I was incredibly lucky not to be in that same situation. I feel like genetic testing saved my breasts.

A single genetic glitch may explain how Zika became so dangerous

A single genetic glitch may explain how Zika became so dangerousBy Julie Steenhuysen CHICAGO (Reuters) – A single genetic change that occurred in 2013 may explain how Zika acquired the ability to attack fetal nerve cells, causing a severe birth defect in babies whose mothers were infected while pregnant, Chinese and U.S. researchers reported on Thursday. Scientists have posited many theories about why Zika, a mosquito-borne virus that had been linked with only mild symptoms since its discovery in 1947, could suddenly be associated with thousands of cases of the birth defect known as microcephaly, as it was in Brazil in 2015.

Neo-Nazis are taking genetic tests and are deeply upset by the resultsWhite supremacists in the US are taking genetic tests to prove their racial identity but are being left bitterly disappointed to learn their genes are not as pure as they presumed. A new study from the University of California examined years’ worth of posts on Stormfront, a neo-Nazi forum which is the internet’s first major racial hate site, to decipher how members responded to their spit-in-a-cup genetic test results. White nationalists were up in arms to discover they were not 100 per cent white European and instead had African, Jewish or Asian genes.

Who's your mummy? Genetic secrets of ancient Egypt unwrapped

Who's your mummy? Genetic secrets of ancient Egypt unwrappedBy Will Dunham WASHINGTON (Reuters) – DNA from mummies found at a site once known for its cult to the Egyptian god of the afterlife is unwrapping intriguing insight into the people of ancient Egypt, including a surprise discovery that they had scant genetic ties to sub-Saharan Africa. Scientists on Tuesday said they examined genome data from 90 mummies from the Abusir el-Malek archaeological site, located about 70 miles (115 km) south of Cairo, in the most sophisticated genetic study of ancient Egyptians ever conducted. The oldest were from about 1388 BC during the New Kingdom, a high point in ancient Egyptian influence and culture.

Woolly mammoths suffered genetic 'meltdown' before extinction

Woolly mammoths suffered genetic 'meltdown' before extinctionBefore woolly mammoths went extinct thousands of years ago, their dwindling population suffered a series of genetic mutations that hampered their ability to survive, researchers said Thursday. Woolly mammoths were once among the most common herbivores in North America and Siberia, but came under threat from increased hunting pressure and a warming climate. Experts analyzed the genome of one of the last known woolly mammoths ever found — a 4,300-year-old specimen from Wrangel Island, off the northern coast of Siberia.
