Article: A food lover’s decision to remove her stomach highlights difficult decisions around cancer risk
Summary
National Public Radio reporter Sáša Woodruff shares her story of learning about her CDH1 mutation and making a decision about risk-reducing surgery. Mutations in the CDH1 gene significantly increase a person’s risk of stomach and breast cancers. Woodruff’s personal essay describes the psychological challenge of making decisions about risk-reducing surgeries and draws attention to a lesser-known mutation linked to hereditary cancer.

ARTICLE AT A GLANCE
This article is about the experience of a woman with a mutation facing an increased risk of an aggressive form of stomach cancer and a high risk of lobular breast cancer.
Sáša Woodruff’s story highlights the difficult preventive decisions carriers face and the sometimes unconventional path to discovering a cancer-causing mutation in one’s family.
Why is this article important?
This article draws attention to a type of cancer-causing mutation that the media rarely covers. mutations cause hereditary diffuse gastric cancer (HDGC) syndrome. People with HDGC have a very high risk of developing aggressive stomach cancer. They also have a high risk of developing a type of breast cancer called lobular cancer. Living with increased cancer risk and making risk-management decisions can cause emotional stress. Because mutations are rare, it may be more difficult for people with mutations to find peer support and resources. Increasing awareness of mutations can lead to more resources and help people with these mutations feel less alone.
Breast cancer runs in Woodruff’s family; her aunt, mom and great-grandmother all had breast cancer, but tests for mutations in affected family members came back negative. A multigene panel test revealed that Woodruff’s sister carried a mutation linked to , which increases the risk for colorectal and other cancers, like pancreatic cancer that her sister had. Woodruff tested negative for . Because would not have caused all the breast cancer in her family, Woodruff pursued additional genetic testing, which revealed her mutation.
What is hereditary diffuse gastric cancer?
Hereditary diffuse gastric cancer is a rare type of stomach cancer that runs in families. Typically occurring at a younger age it is difficult to detect in its early stages because it grows throughout the lining of the stomach. By the time the cancer is big enough to find with screening tools such as upper endoscopy, it is usually advanced. About half of HDGCs are caused by inherited mutations in the gene. mutations can also increase the risk of lobular breast cancer, a type of breast cancer that develops in the glands that make milk.
How does HDGC syndrome affect cancer risk?
Experts note that while mutations can increase cancer risk, this risk may vary widely. Some people with an inherited mutation do not have a family history or personal history of related cancers. Others have a family history of lobular breast cancer but not stomach cancer. This makes it difficult to predict the risk of cancer in people with a mutation. For this reason, genetic counselors often look at family history to help people with mutations understand their risk for cancer and to provide recommendations for managing that risk. Current expert guidelines list the following risks:
For people assigned female at birth:
- 40 to 60% chance of developing lobular breast cancer
- 83% lifetime risk for stomach cancer
For people assigned male at birth:
- 67% lifetime risk for stomach cancer
The lifetime risk of stomach cancer in the general population is less than one percent. For a person with an inherited mutation, the lifetime risk of developing diffuse gastric cancer can be up to 83 percent and often occurs at younger ages (the average age at diagnosis is 37).
Risk-reducing strategies for hereditary stomach cancer
Due to Sáša Woodruff’s family history of stomach, colon and breast cancer, her healthcare providers strongly recommended a total gastrectomy (stomach removal) to prevent the deadliest cancer that ran in her family.
In her article, Woodruff talks about screening for people who are at risk for hereditary diffuse gastric cancer. The screening procedure is done under anesthesia and involves looking at the stomach using an endoscope (a thin tube with a camera that is threaded through the mouth to the stomach). The doctor takes about 30 biopsies in different parts of the stomach lining to test for cancer. Even with this invasive screening, diffuse stomach cancer is usually detected at an advanced . For this reason, experts recommend gastrectomy to prevent the disease.
Expert guidelines for risk management in people with mutations include the following:
For managing risk of stomach cancer
- Risk-reducing surgery to remove the stomach between the ages of 18-40 years
- Screening every 6–12 months by upper endoscopy with multiple random biopsies for people who have not had surgery
For managing the risk of breast cancer
- Yearly beginning at age 30
- Discussion with a doctor about the benefits, risks and costs of an annual breast
- Discussion with a doctor about the benefits, risks and costs of risk-reducing mastectomy
Difficult decisions
Gastrectomy surgery results in major lifestyle changes. In her article, Woodruff writes about her grief surrounding the loss of her stomach because she loves eating, and food is significant for her cultural and social identity. She couldn’t imagine life without a stomach. Woodruff writes about the idea of a preventive gastrectomy, saying:
“It was new to me, unimaginable and frankly, it felt barbaric.”
The stomach helps break down food so the body can easily absorb nutrients. However, most of the digestion happens in the small intestine, where the food is passed after it leaves the stomach. For this reason, people can live relatively normal lives without a stomach. During a total gastrectomy, surgeons remove the entire stomach and attach the esophagus to the small intestine. This changes what and how much food a person can eat, but most people can eventually eat small portions of most of the foods they previously enjoyed.
After making peace with her decision to undergo a total gastrectomy, Woodruff also wrote:
“There are many people who live full, if not altered lives, without a stomach. There are few happy endings with stomach cancer.”
Recovering from stomach removal
Recovery from a total gastrectomy takes time and patience. People often lose weight for a couple of months after their gastrectomy. They may experience symptoms like abdominal cramping, pain, diarrhea and lightheadedness when food moves too fast through their digestive system. These symptoms usually resolve over time. A year after surgery, most people have settled into a new normal with their eating habits.
Woodruff wrote this article just before her gastrectomy. Seven months after her surgery, she spoke about her experience on NPR, saying:
“Once you don’t have a stomach, you actually realize that you don’t really need one.”
Risk-reduction strategies for lobular breast cancer
People with a mutation have a high lifetime risk of lobular breast cancer. Because breast cancer is more easily detected at its early stages, some people choose increased surveillance. Alternatively, because of the high lifetime risk of breast cancer, risk-reducing surgery to remove breast tissue ( mastectomy) may be an approach to consider for women with an inherited mutation.
What does this mean for me?
Diffuse gastric cancer is rare in the general population, but people with a mutation have a very high risk of developing the disease. If you have been diagnosed with HDGC syndrome because of a mutation, make sure you speak with a genetic counselor, who will closely assess your family history of cancer.
Because no reliable screening method exists for detecting diffuse gastric cancer, expert guidelines recommend that people with HDGC syndrome have surgery to remove their stomach. The recommended age for surgery varies and may depend on your family history.
While these surgeries can reduce your cancer risk, they can be life-changing. You should carefully weigh the pros and cons of the procedures with a team of experts before making a decision.
People with a mutation have a high risk of lobular breast cancer in their lifetimes. You may want to discuss with your doctor the most appropriate screening or prevention approaches for your personal and family history.
