How can a lump in the abdomen be related to stomach cancer?

Stomach cancer usually begins in the inner lining of the stomach, but as it grows and progresses, it can invade deeper layers and spread (metastasize) to nearby tissues. In some cases, this spread can cause masses that can be felt or seen as lumps in the abdomen. For example, the cancer might spread to nearby lymph nodes, the peritoneum (the lining of the abdominal cavity), or even the abdominal wall itself. These lumps are often signs that the cancer is advanced. Imaging tests, such as CT scans or ultrasounds, are used to detect these abnormalities. If a lump is found in the context of stomach cancer, it often indicates local invasion or distant spread of the disease, which helps doctors determine the stage of the cancer and plan treatment accordingly.
