Stomach cancer starts in the cells of the inner lining. It can grow into a tumour or spread to other areas of the body.
This page provides estimates for global estimates of stomach cancer incidence and deaths as well as Disability-Adjusted Live Years (DALYs). The data are taken from GBD 2017. This data can help countries develop strategies to reduce stomach cancer rates.
Risk Factors
Stomach cancer develops when there is an alteration (change) in the DNA of stomach cells that causes them grow and enlarge, thereby taking over healthy cells instead of dying. This can cause tumors to develop in the stomach lining or extend to other parts of the body. Scientists aren’t sure what causes these mutations however certain factors increase the risk of stomach cancer. These include infection with the bacteria Helicobacter Pylori and the presence of stomach polyps and ulcers eating a diet low in vegetables and fruits, smoking, and alcohol consumption.
The stomach is a hollow, Stomach cancer railroad cancer muscular organ that takes in food that is chewed, and then releases acid and enzymes to help digestion. It also stores vitamin B12. The mucus membrane of the stomach is made up of glandular and columnar epithelial cells, which are surrounded by muscles. In most cases stomach cancer occurs in the stomach’s cells. This kind of cancer is known as adenocarcinoma and usually occurs in males and older adults.
The risk of developing stomach cancer increases with age. It is more common among women than men and is more likely to occur in people with an ancestral history of the cancer. A history of stomach ulcers and a diet rich in processed foods, such as pickled, smoked or salty foods can increase the risk of developing stomach carcinoma.
Signs and symptoms
Stomach cancer, also called gastric cancer, occurs when the cells that line your Stomach cancer railroad cancer begin to grow out of control and develop into an abnormality. This type of cancer usually grows slowly over time however, it can also expand to other parts of the body. It’s unclear what causes the cancer. It could begin in the glandular tissue that line the stomach’s interior (adenocarcinoma) or originate from other kinds of cancers that develop from cells in the blood or connective tissues (sarcoma). Most cases of stomach cancer are adenocarcinomas however, a few people develop other types of cancer that start in other organs, like the breast cancer and melanoma and then it spreads to the stomach.

They may also perform an positron-emission CT scanner or PET CT scan, which gives more information than the CT alone on the impact of cancer on the body.
Diagnosis
Stomach cancer develops when the normal cells of the upper digestive tract begin to grow uncontrollably and change into abnormal. Cancer can grow and spread (metastasize) to other organs in your body.
A change or mutation in a person’s genetic code can cause stomach cells grow faster than normal and develop tumours. The tumours may cause damage to healthy stomach cells liner. Cancer that has taken hold of the stomach and spread to other parts of the body may cause symptoms like weight loss and fluid build-up in the abdomen (ascites).
Your doctor will look for indications of stomach cancer performing a test referred to as an endoscopy. This involves the passing of a long, thin flexible tube equipped with cameras (an endoscope) into your mouth, down your throat and into your stomach. The endoscope has a tiny camera that can take pictures of the digestive tract. A biopsy can also be taken at this point should it be required.
Other tests can help find out if you have stomach cancer stomach cancer and how far it has gotten. These tests include CT scans, PET scans, an ultrasound or laparoscopy. These tests can aid your doctor in determining the most effective treatment option for you. You might be referred to a specialist in cancer (oncologist) or a specialist in your digestive system (gastroenterologist). The kind of treatment you’ll receive will depend on the stage of your cancer, how far it has spread and the other health issues you may have.
Treatment

Lymphomas are formed in lymph tissue, which is a kind of immune system tissue. Certain types of lymphoma like MALT (mucosa-associated lymphoid tissue) lymphoma, are more likely to be found in the stomach than others.
