About stomach cancer
Stomach cancer, or stomach cancer, is a relatively rare type of cancer.
The first symptoms of stomach cancer are vague and easy to confuse with other serious diseases. It includes:
constant indigestion and heartburn
trapped wind, constant humming
feeling too full or bloated after eating
persistent stomach pain
Advanced symptoms of stomach cancer include:
blood in the stool or black stools
loss of appetite
The early symptoms of stomach cancer are similar to those of many other diseases, so the cancer is advanced before it is diagnosed. Therefore, it is important to get the symptoms of stomach cancer checked by a doctor as soon as possible.

Types of stomach cancer
There are several types of stomach cancer. More than 95% of stomach cancers arise in the cells of the lining of the stomach, called adenocarcinoma.
Rare types of stomach cancer include gastric lymphomas that develop in the lymphatic tissue (tissue that drains fluid and helps fight infection), and gastrointestinal stromal tumors (GISTs) that develop in the muscle or connective tissue of the stomach wall. .
How is stomach cancer treated?
Although many cases of gastric cancer cannot be completely cured, it is still possible to relieve symptoms and improve quality of life with chemotherapy and, in some cases, radiation therapy and surgery.
If surgery can remove all the tumor tissue, surgery can cure stomach cancer.
Surgery to remove part or all of the stomach is called a gastric bypass. After gastric bypass surgery, you will still be able to eat normally, but you will need to adjust the amount of food you eat.
Chemotherapy may be used before surgery to shrink the tumor and sometimes after surgery to prevent the tumor from coming back.
