What is stomach cancer?
Stomach cancer is also known as gastric cancer. It starts when the cells in the lining of the stomach grow and divide in an abnormal and uncontrolled way. Over time, the cells form a tumor that is cancer. The tumor may stay in the stomach. It also could spread to other organs, such as the liver, lungs, or the lining of the wall of the abdomen (belly).
Early-stage stomach cancer often causes almost no symptoms. Sometimes, people have an upset stomach and general stomach discomfort. But these symptoms also are common signs of other things, such as indigestion or a stomach virus. That’s why it’s hard to diagnose stomach cancer in its earliest stages.
Later stage (stage 4) stomach cancer already has spread. Symptoms of advanced stomach cancer are easier to spot. That often leads to testing, and then to a diagnosis of stomach cancer.
There are a few things you can do to lower your risk for stomach cancer. For example, you can change your diet and lifestyle.
There are other risk factors we cannot change, including the genes you were born with.
You can learn more about the risk factors for stomach cancer and how to prevent it.
MSK diagnoses stomach cancer using many new technologies that we developed or improved. We’re always researching ways to diagnose cancer with greater accuracy, which lets us improve treatment results.

The MSK difference
Why chose MSK to diagnose and treat gastric cancer?
Memorial Sloan Kettering Cancer Center (MSK) is known for its team of gastric cancer experts. We see more people with gastric cancer than any other cancer center in the United States.
MSK’s robotic gastric cancer program does more robotic gastrectomies than any other hospital in the country. Our surgeons have done nearly 1,000 gastric cancer procedures, using the latest robotic methods.
Each year, MSK gastric cancer experts:
- Treat more than 200 people just diagnosed with gastric cancer.
- Do about 150 gastric cancer procedures.
MSK is one of the few National Cancer Institute-designated cancer centers that has a program just for upper gastrointestinal tract cancers.
