What is stomach cancer?
Stomach cancer, also known as gastric cancer, is a disease that starts in the cells of the stomach. It is the fifth most common cancer worldwide and the third leading cause of cancer-related deaths. Stomach cancer occurs when healthy cells in the stomach undergo genetic mutations, causing them to divide and grow uncontrollably. Over time, these abnormal cells form a tumor. If left untreated, stomach cancer can spread to nearby organs and lymph nodes, making it more challenging to treat effectively.
Definition of stomach cancer
Stomach cancer refers to the growth of malignant cells in the lining of the stomach. It encompasses various types, such as adenocarcinomas, which account for the majority of stomach cancer cases, as well as less common types like lymphomas and gastrointestinal stromal tumors (GISTs). The symptoms of stomach cancer can vary, but they often include indigestion, abdominal pain, nausea, unintentional weight loss, and a feeling of fullness even after consuming small amounts of food. Early detection and timely treatment are crucial for improving the prognosis and increasing the chances of survival.
Causes and risk factors of stomach cancer
While the exact causes of stomach cancer remain unclear, several risk factors have been identified. These include infection with the bacterium Helicobacter pylori, which is commonly associated with stomach ulcers, certain genetic conditions, a family history of stomach cancer, a diet high in salted or smoked foods, and exposure to certain chemicals and substances such as asbestos. Other factors that may increase the risk of developing stomach cancer include smoking, obesity, having a weakened immune system, and specific medical conditions like pernicious anemia and chronic gastritis.
