Chemotherapy is a common treatment for stomach cancer that can help control the growth and spread of cancer cells. However, chemotherapy does not guarantee that stomach cancer tumors will disappear and not grow again. Treatment options for stomach cancer are usually comprehensive, including surgery, radiation therapy, and chemotherapy. Surgery can remove tumor tissue, radiation therapy can destroy tumor cells, and chemotherapy can help control the growth of cancer. Chemotherapy may achieve the following results: 1. Partial or complete shrinkage of the tumor: Chemotherapy can shrink the tumor or even completely disappear in some cases. In this case, the treatment can be considered successful. 2. Control and slow the growth of the tumor: Chemotherapy can help control the growth of cancer and slow the growth rate of the tumor. This can help patients live longer. 3. Control symptoms: Even if it cannot completely cure stomach cancer, chemotherapy can help relieve symptoms and improve the patient`s quality of life. It is important to understand that each patient`s situation is different and responds differently to chemotherapy. Some patients may respond positively to chemotherapy, while others may not be sensitive to chemotherapy. You should discuss your individual situation with your doctor and understand the treatment options that are most suitable for you.
