Stomach Cancer Treatments
The correct answer regarding stomach cancer treatment is that chemotherapy and radiation therapy are often used as part of a treatment regimen. These methods, as well as surgery, are among the primary treatments for various types of cancer, including stomach cancer. The effectiveness of chemotherapy and radiation depends on several factors, such as the cancer's type, location, and stage. Early diagnosis and treatment significantly increase the chances of a successful outcome. However, while chemotherapy and radiation can be successful, they may not always be curative.
Radiation therapy works by using ionizing radiation to kill cancer cells, often used in conjunction with other treatments like surgery and chemotherapy. It is designed to target the cancerous tissues while minimizing damage to surrounding healthy tissues. In addition to these treatments, other methods such as immunotherapy, monoclonal antibody therapy, and hormonal therapy might be utilized depending on the specifics of the case.
