The stomach is a part of the digestive system. It is a muscular sac located in the upper abdomen below the ribs. The stomach receives the food ingested, and partial digestion takes place in the stomach. The stomach has gastric juices that aid the breakdown
Stomach Cancer is the metastasis of cells in the stomach. It can affect any part of the stomach, the stomach body being the most predominant.

What are the Causes of Stomach Cancer?
- ● Infection with H.pylori, which causes ulcers.
- ● Prolonged condition of gastritis (inflammation in the gut).
- ● Pernicious anaemia.
- ● Polyps in the stomach.
What are the Symptoms of Stomach Cancer?
- ● Indigestion.
- ● Feeling bloated after every meal.
- ● Heartburn.
- ● Nausea.
- ● Loss of appetite.
Symptoms at later stages:
- ● Stomach pain.
- ● Bloody stool.
- ● Vomiting
- ● Unexplained weight loss.
- ● Difficulty swallowing.
- ● Yellowish eyes or skin.
- ● Constipation or diarrhoea (varies from patient to patient).
- ● Swelling in the stomach.
- ● General weakness.
- ● Heartburn.
Early signs and symptoms do not indicate cancer. If you present with these signs, talk to your doctor to make a definitive diagnosis based on the examinations prescribed accordingly.
How is Stomach Cancer Diagnosed?
- ● Endoscopy: A thin tube with a camera at the tip is inserted into the stomach via a patient’s mouth, down the throat. The doctor will look for any lesions or other signs of cancer.
- ● Biopsy: If the doctor finds any abnormality in the endoscopy, he will use special tools to excise a small part of the tissue and send it for further analyses. The sample is sent to the lab to check for malignant cells.
- ● CT scan: This is an imaging test done to confirm the diagnosis.
- ● Barium swallow test: This is a special imaging test mainly done to detect Stomach Cancer.
Staging of Cancer
It is important to know at which stage is the patient to determine the treatment plan. Your doctor will assess your clinical situation and test reports, and then staging is determined. The stages of cancer are indicated by Roman numerals, ranging from 0 to IV, with stage 0 being an early precancerous stage and stage IV being advanced and has spread to other parts of the body.
How is Stomach Cancer Treated?
- ● Surgery: The cancerous mass is surgically excised along with a part of the normal tissue surrounding it. A portion of the normal tissue is included to reduce the chances of recurrence and to ensure that the entire cancerous mass is removed.
In case of Stomach Cancer
- Early-stage tumours are removed by endoscopic mucosal resection and endoscopic submucosal resection.
- Subtotal gastrectomy becomes an option if cancer is in the stomach near the small intestine.
- Total gastrectomy is recommended if the cancer is in the body of the stomach and involves the gastroesophageal junction. The esophagus is then connected directly to the small intestine to allow food to move through the digestive system.

What are the Risks Associated with Stomach Cancer treatments?
- ● Bleeding
- ● Blood clots.
- ● Damage to adjacent tissues.
- ● Rarely, the new connection between the stomach and esophagus may leak.
You will not be allowed to eat or drink for a couple of days after a total or subtotal gastrectomy to ensure healing and prevent leakage.
What are the Other Treatment options Associated with Stomach Cancer treatments?
- ● Chemotherapy: It is a drug treatment where the patient is put on a series of medications to kill cancer cells. This is recommended if cancer has started to spread to the other parts of the body. The drugs will enter the bloodstream and kill cancer cells in the body. Chemotherapy is given both before and after surgery. Before surgery, it is given to shrink cancer and make it easy to remove it through surgery, and after surgery, it kills the cancer cells that might be present in the body in unknown regions. Chemotherapy is often given along with radiation therapy or targeted drug therapy in advanced stages.
- ● Radiation therapy: Similar to chemotherapy, radiation therapy can also be given before or after surgery. Here, high-energy beams of protons and X-rays are given that move around the body, killing the cancer cells. In advanced cases, radiation therapy is used to relieve pain and other side effects.
- ● Targeted drug therapy: This focuses on specific weaknesses that may be present within the cancer cells. This is preferred in advanced stages of stomach cancer.
- ● Immunotherapy: It is a method to boost the body’s immune system to fight cancer cells. Normally, the immune system does not recognize the cancer cells as dangerous because they produce proteins. Immunotherapy interferes with this process and boosts the immune system. In Stomach Cancer, it is used in advanced stages.
- ● Palliative treatment: Supportive measures are taken for you and your family. The aim here is to improve your quality of life. This is carried out alongside the ongoing treatment.
