This is reason that so many people with stomach cancer are not diagnosed until the disease is already advanced.The following signs and symptoms should be seen as urgent in people at increased risk of developing stomach cancer.

1. Everything you need to
know
about
stomach cancer

2. Stomach cancer, also known as gastric cancer,
is a buildup of abnormal cells that form a
mass in part of the stomach.
According to the World Health Organization
(WHO), 723,000 cancer-related deaths are
caused by stomach cancer each year worldwide.
It is the fifth most common cancer worldwide,
but the third leading cause of cancer-related
deaths.

3. Fast facts on stomach cancer
Here are some key points about stomach cancer. More
detail and supporting information is in the main article.
• Stomach cancer is the third leading cause of cancer-
related deaths.
• The most common type of stomach cancer is
adenocarcinoma of the stomach.
• Early symptoms include heartburn ,
persistent indigestion, and difficulty swallowing.

4. Symptoms
There are several symptoms associated with stomach cancer.
However, as they also exist in many other less serious
conditions, gastric cancer may be difficult to recognize at first.
a sensation of being very full during meals
swallowing difficulties, known as dysphagia
feeling bloated after meals
frequent burping
heartburn
stomachache, or pain in the breastbone
fatigue
loss of appetite
weight loss

5. Causes
Cancer starts when the structure of DNA changes.
When this happens, it can disrupt the instructions
that control cell growth.
Cells that should die may not do so, and cells that
should be newly created may be produced too
rapidly or in an uncontrollable way.
Experts are not sure why some stomach cells
mutate and become cancerous. It is not known why
only a few people develop stomach cancer.

6. Treatment
Treatment for stomach cancer depends on
several factors, including the severity of the
cancer and the individual's overall health and
preferences.
Treatments may include
surgery, chemotherapy, radiation therapy,
medications, and taking part in clinical trials.

7. Surgery
The surgeon's aim is to remove the stomach cancer from the
body as well as a margin of healthy tissue. This is necessary to
make sure no cancerous cells are left behind.
Examples include:
Removing tumors from the stomach lining in early-stage cancer:
The surgeon will use endoscopy to remove very small tumors that
are confined to the inside lining of the stomach. This is called
endoscopic mucosal resection.
Subtotal gastrectomy: A part of the stomach is surgically removed.
Total gastrectomy: The whole stomach is surgically removed.
