Stages of stomach cancers are difficult to understand. The stages are ..
Stage 0 (Carcinoma in Situ)
This is the first stage of stomach cancer that also referred as carcinoma in situ because cancer doesn’t spread the nearby tissue. In this stage, abnormal cells become cancer and spread into nearby normal tissue.
This is the next stage of stomach cancer. In this stage cancer formed in the inside lining of the stomach wall.
- Cancer may have spread into the submucosa of the stomach wall.
- Cancer may have spread into the submucosa of the stomach wall and found in lymph nodes near the tumor or
spread to the muscle layer of the stomach wall.
Cancer has grown from the top layer of the mucosa to the next layers lamina propria. The cancer started growing into the subserosa layer. The tumor has grown through the stomach wall to the serosa, but the cancer hasn’t grown into any of the nearby organs.
In the third stage of stomach cancer, Cancer has grown through the stomach wall into the serosa. the cancer cell has grown from the top layer of cells of the mucosa to the next layers lamina propria, the muscularis mucosa, or submucosa and it spread to 7-15 nearby lymph nodes. It has not spread to distant sites.
In stage IV, cancer has spread to distant parts of the body.
