Genetic Counseling Plays Important Role in Making Life-Saving Health Decisions

Genetic testing can identify 80 different genes associated with cancer

In some cases, it’s easy to see what we’ve inherited from our family, like mom’s smile or dad’s blue eyes, but when it comes to certain health conditions, genetics may play a critically important role for generations. Here’s the story of one extended family with a genetic form of stomach cancer, and the courageous, but potentially life-saving decision many members chose to make.

Fifty-four-year-old Beth Lambert comes from a big family. She’s one of five siblings, but in 2006, her brother Steve died from a rare form of stomach cancer.

“Just watching our brother go from someone who was so full of life, and he really was as much as he could be up until the end,” Lambert said.

At the same time, their mother was battling colon cancer. Her cancer cells had the same unusual signet cell pattern asher brother’s. An alert physician suggested a genetic test. Kristen Shannon is a certified genetic counselor at Massachusetts General Cancer Center. She says a huge increase in the number of testing labs has made a recent, dramatic difference in the field.

“In addition to BRCA1 and BRCA2, we can test for up to 80 different genes that are associated with cancer,” Shannon explained.

One of those genes – the CDH1 mutation – is responsible for the aggressive stomach cancer that claimed Lambert’s brother.

“My sister Kathy tested positive. My brother Mike tested positive. Our brother Dave tested negative and then I tested positive,” said Lambert.

Since the cancer involved the lining of the stomach, prevention meant having their stomachs surgically removed.

Lambert and her brother Mike scheduled their surgeries on the same day, then, the focus shifted to the next generation. Mike’s daughter Shannon Walsh tested positive for the CDH1 gene in college. She also chose to have her stomach removed.

“It went from a, ‘You can wait as long as you want, sort of within reason’ to, ‘You should really think about doing this,’” said Walsh.

Lambert and her family eat small meals. No food is off limits, but some are easier to process than others. Despite the challenges, Lambert is thankful their mother started them on the path to uncovering their genetic risk.

“If she hadn't done that, you know, we'd be telling a very different story. We probably wouldn't be here to tell this story, to be honest,” Lambert said.

Lambert and her family take nutritional supplements to compensate for foods they have a hard time processing. In addition to Lambert’s niece, one of her children, and two of her late brother Steve’s children have tested positive for the stomach cancer gene. The family is involved in a non-profit group called No Stomach for Cancer to raise awareness and money for research. They also say it’s important to pay attention to your family health history, and if illness seems to follow a pattern, find a genetic counselor to offer guidance.
