Gastric Cancer, also known as Stomach Cancer, develops in the lining of the stomach. It is often found in people above 55 years of age, and is twice as likely to affect men than women. It is predominant in countries that consume food preserved through pickling, smoking, drying or salting.
A common bacterium called Helicobacter pylori, also called H. pylori, causes stomach inflammation and ulcers, and is considered to be one of the primary causes of Stomach Cancer. The cancer can often be silent in initial stage and get diagnosed when it has metastasized to organs such as lungs, bones, liver, and lymph nodes.
The early symptoms of Gastric Cancer are not prominent, which leads to its late diagnosis. Some of the prominent symptoms are loss of appetite, sudden loss of weight, vomiting, black coloured stools, stomach aches and bloating sensation. It is diagnosed by gastroscopy and biopsy. A PET-CT scan would help in staging of cancer.
The conventional methods of treatment include chemotherapy, radiation therapy, surgery and immunotherapy.
