Know about Stomach Cancer (Gastric Cancer)
When cells begin to behave improperly, multiplying and reproducing uncontrolled, stomach cancer develops. Gastrointestinal (GI) cancer refers to malignancies of the oesophagus, pancreas, stomach, colon, rectum, anus, liver, biliary system, and small intestine that affect the gastrointestinal tract and other organs contained within the digestive system. While stomach cancer is relatively uncommon in comparison to other cancers, one of the most serious risks is the difficulty in diagnosing it. Due to the lack of early signs, stomach cancer frequently stays undetected until it has spread to other regions of the body. This makes treatment more challenging.
Risk factors of stomach cancer
Tumours in the stomach are connected to stomach cancer. There are, however, several variables that may raise your chances of acquiring malignant cells. Certain illnesses and disorders are among these risk factors, including:
- tumours in other areas of the gastrointestinal tract
- lymphoma (a group of blood cancers)
- a common stomach infection that can develop to ulcers in some people
- tissue growths that develop abnormally on the stomach lining(stomach polyps)
Symptoms
- Fatigue or weakness
- Weight loss
- nausea and vomiting
- jaundice
- Bleeding (vomiting blood or passing blood in stools)
- stomach pain, which may be worse after meals
Screening/Diagnosis
Due to the rare symptoms in the early stages of stomach cancer, it is frequently not identified until the illness has advanced. Your doctor will do a physical exam to look for any abnormalities before making a diagnosis. They may also request a blood test, which may include a check for H. pylori bacteria. If your doctor suspects you have stomach cancer, you will need to undergo additional diagnostic testing. Diagnostic testing in the stomach and oesophagus checks for suspected cancers and other abnormalities. These tests may involve the following:
- Upper GI series: The patient is instructed to consume a barium solution for the upper GI series. Following that, stomach x-rays are taken. The barium outlines the inside of the stomach, assisting in the detection of any abnormal regions that might be cancerous. This test is no longer as common as it once was, and patients are now more likely to undergo an endoscopy first.
- Endoscopy and biopsy - An endoscope is a lighted, flexible tube with a camera that is put via the mouth, down the oesophagus, and into the stomach. Before the insertion of the endoscope, sedation is administered. Biopsies (tissue samples) can be collected and analysed under a microscope to search for cancer cells if an abnormal region is discovered.
Endoscopic ultrasonography can also be used to conduct gastric cancer staging. Endoscopic ultrasonography can be used to check for any enlarged lymph nodes that may be invaded with cancer cells, as well as to detect the depth of the tumour’s spread into the stomach wall and its involvement with surrounding tissues.
Treatment
The most frequent treatment is surgery. The surgeon might remove a portion of the stomach or the complete stomach (gastrectomy). During surgery, the lymph nodes around the tumour are usually removed to screen for cancer cells. Chemotherapy may be used before surgery to help reduce the tumour and after surgery to help destroy any remaining tumour cells, according to researchers. Depending on the medicines used, chemotherapy is administered in cycles with intervals of several weeks. The use of high-energy rays to destroy cancer cells and stop them from developing is known as radiation treatment. Only the cancer cells in the treated region are destroyed by radiation.
