What are the stomach cancer phases?
stomach cancer is cancer that affects the stomach. Tests are often carried out to determine the stomach cancer stages or how much cancer has spread. Phase 0 describes cancer found in the lining of one layer of stomach, while Phase 1 is a point at which it spread throughout the layer and up to six lymph nodes. Stomach 2 cancer shows that the disease has spread either to other layers of the stomach or to nearby lymph nodes. The most serious stomach cancer stages are phases 3 and 4, in which cancer cells are at least seven lymph nodes, in other layers of the walls of the stomach or other organs. This is also called carcinoma in situ. Phase 1 is slightly more serious and is divided into two categories. In phase 1a stomach cancer, the stomach wall attacked the entire inner layer of the stomach wall. Phase 1b describes a maycer that spreads so far and up to six lymph nodes or into a middle stomach layer.
Another stage of stomach cancer is phase 2 in which there are three options. The first is that cancer has attacked the entire innermost layer of the stomach wall, as well as from seven to 15 nearby lymph nodes. The second option is that cancer has spread to the middle of the middle stomach wall, except for six lymph nodes. The third possibility of stomach cancer in phase 2 is that it has spread to the outer layer of the stomach wall, but not to any lymph nodes.
One of the more serious stomach cancer stages is phase 3, which has two categories. Phase 3a shows that cancer cells were found in the middle wall of the stomach and from seven to 15 nearby lymph nodes. Another possibility of phase 3a is that cancer has spread to the outer layer of the stomach wall and from one to six lymph nodes. Cancer, which has spread to other nearby organs, but not to any lymph nodes, can also qualify as phase 3A. On the other side of phase 3b indicates that it has spread to the outerstomach layers and seven to 15 lymph nodes.
The most serious of all stomach cancer stages is phase 4. This phase suggests that cancer cells were found in organs near the stomach and in one or more lymph nodes. Cancer, which affects either more than 15 lymph nodes or other areas of the body, is also calculated as Phase 4. Many people find the most advanced stages of stomach cancer such as phases 3 and 4, do not respond to conventional treatment because cancer has spread.
