Medically reviewed on Nov. 30, 2023.
Gastric cancer, also called stomach cancer, includes a group of cancers that originate in your stomach. The most common stomach cancer is adenocarcinoma, which starts in your stomach’s surface layer. Less common types of stomach cancers affect your stomach’s middle or outer layers.
At UC Davis Comprehensive Cancer Center, you receive world-class care for any type of stomach cancer. Our center is one of the few in the nation with a comprehensive cancer center designation from the National Cancer Institute. We provide the newest innovations in gastric cancer therapies through our ongoing research.
You may not feel symptoms when stomach cancer is in the early stages. Usually, people only have symptoms after the tumor gets larger or the cancer spreads to another area of the body.
Early stage symptoms of stomach cancer include:
As the tumor grows or spreads, you may notice:
Gastric cancer occurs when the DNA in your stomach cells mutates (changes). The DNA tells your stomach cells to grow out of control. Over time, these uncontrolled cells form a tumor that can grow and spread to other areas of your body.
In most cases, there is no single cause of stomach cancer. DNA mutation is often a result of many different factors, including your genetics and things in your environment.
There are also risk factors that may cause you to be more likely to develop stomach cancer:
H. pylori is a bacterium (germ) that infects your stomach’s lining. People with this bacterial infection are more likely to develop stomach cancer than people without the infection.
A family history of stomach cancer or specific cancer syndromes raises your risk of stomach cancer. Cancer syndromes include familial adenomatous polyposis (FAP), juvenile polyposis syndrome, Lynch syndrome, and CDH1 gene mutation.
Most cases of stomach cancer affect people ages 65 or older.
People who eat more red and processed meats and fewer fruits and vegetables may be more likely to get stomach cancer.
Stomach cancer is more likely to affect Pacific Islanders and African, Asian, Hispanic and Native Americans.
If you had a prior stomach surgery or stomach polyps (growths), you could be more likely to develop stomach cancer.
Smoking increases your risk of getting stomach cancer.
People who have excess weight or obesity are more likely to develop stomach cancer.
UC Davis Comprehensive Cancer Center experts have decades of experience diagnosing stomach cancer. We provide the latest tests so you get answers.
First, we perform a physical exam and discuss your medical history. Our compassionate team answers your questions and listens to your concerns. Then, we may recommend medical tests, including:
At UC Davis Comprehensive Cancer Center, you receive a personalized stomach cancer treatment plan. Our team works together to target the specific type, stage and location of cancer.
We have the largest and most comprehensive cancer center in inland Northern California. We provide every specialty you need and ongoing support and guidance at each step. You also have access to clinical trials offering the latest breakthroughs in stomach cancer treatment.
Your treatment plan may include:
Our Department of Hematology and Medical Oncology provides the latest chemotherapy medications for stomach cancer. Hyperthermic intraperitoneal chemotherapy (HIPEC), which puts chemotherapy drugs directly in your abdomen, can work well for stomach cancers. Our specialists customize your medication for maximum results.
At our center, you have access to the full range of advanced immunotherapy options. These treatments help your immune system detect and fight cancer cells. Our experts carefully evaluate the tumor’s characteristics and select the immunotherapy medication that will work best.
Experts in our Department of Radiation Oncology are national leaders in radiation therapy. Our physicians and physicists provide the latest radiotherapy advances for the best results with fewer side effects.
Also called chemoradiotherapy, this advanced therapy combines chemotherapy and radiation therapy. This customized combination often provides better outcomes than one of these treatments alone.
Our Division of Surgical Oncology includes surgeons who specialize in treating stomach cancer. We provide every type of gastric cancer surgery, including subtotal and total gastrectomy, and laser therapy.
Early stage gastric cancer may be removed through the nose. Endoluminal stents may also be placed for advanced stage cancer to ease the pain without removing the cancer.
As innovators and pioneers in cancer care, our specialists are at the forefront of the latest targeted therapy medications. These drugs target cancer cells to slow their growth or kill them. We perform specialized tests on the tumor’s cells to identify the most effective option for you.
You cannot always prevent stomach cancer, but you can lower your risk if you:
Research shows that not smoking will lower your risk of stomach cancer.
You can decrease your chance of getting stomach cancer by consuming more fruits and vegetables and less red and processed meat.
Regular walking and other exercises can lower stomach cancer risk.
Losing excess pounds could help you prevent stomach cancer and other health problems.
