What Is Stomach Cancer? Cancer occurs when cells in a part of the body begin to grow out of control. There are many kinds of cancer and they all come about because of out-of-control growth of abnormal cells. Different types of cancer behave very differently. Lung cancer, breast cancer, vaginal cancer, and liver cancer are very different diseases. The diseases grow at different rates and respond to different treatments. People with cancer need treatment that is aimed at their kind of cancer.
Stomach cancer, also called gastric cancer starts in the stomach. The stomach is divided into five different layers. Cancer can develop in any of these sections.
The stomach is composed of five layers. Starting from the inside and working our way out, the innermost layer is called the mucosa. Stomach acid and digestive juices are made in the mucosa layer. The next layer is called the submucosa. The submucosa is surrounded by the muscularis, a layer of muscle that moves and mixes the stomach contents. The next two layers, the subserosa
and the serosa are the wrapping for the stomach. The serosa is the outermost layer of the stomach.
Most stomach cancers start in the mucosa. The cancer can grow deeper and infect the other layers. As it grows deeper, the outlook for a cure gets worse.
Stomach cancers grow slowly over many years. Cancer just doesn't suddenly appear. As the cancer develops, there are usually changes that occur in the lining of the stomach. These early changes usually do not produce symptoms and are often are unnoticed.
How does Stomach Cancer spread? Stomach cancer can spread to different parts of the body. It can grow through the wall of the stomach and into nearby organs or it can also spread to the lymph nodes and then through the lymph system.
When stomach cancer is more advanced, it will travel through the blood stream and form deposits of cancer cells in organs such as the liver, lungs, and bones. But even though it has spread to other organs, it is still called stomach cancer. If it has spread in this manner, it can no longer be cured.
Types of Stomach Cancer: There are three main types of stomach cancers: lymphomas, gastric stromal tumors, and carcinoid tumors. Lymphomas are cancers of the immune system tissue that are sometimes found in the wall of the stomach. Gastric stromal tumors develop from the tissue of the stomach wall. Carcinoid tumors are tumors of hormone-producing cells of the stomach.
