Oral cancer treatment methods can vary depending on the patient's overall health, the cancer's origin, and its stage. Surgical intervention is the most common treatment for oral cancer, involving the removal of the tumor and a margin of surrounding healthy tissue. In cases where cancer cells have spread to the lymph nodes, the surgeon may also remove these nodes to prevent the cancer from spreading to other parts of the body. A notable advancement in oral cancer treatment is the increasing use of robotic surgery. Radiotherapy targets cancer cells using high-energy X-rays and can be the primary treatment for some small tumors. In certain cases, it is also applied after surgery to eliminate microscopic cancer cells that might remain in the body. Even if radiotherapy cannot completely cure the cancer, it can alleviate symptoms such as bleeding and difficulty swallowing. Chemotherapy may be administered when deemed necessary by doctors, primarily to shrink tumors before surgical procedures. In cases where the tumor is too large for surgery, a combination of chemotherapy and radiotherapy can help manage the symptoms caused by the cancer. When cancer is diagnosed at an early stage, such as Stage I and II, the chances of recovery significantly increase. Tumors at these stages are typically smaller than 4 centimeters at their widest point and have not spread to the lymph nodes. Early-stage cancers can usually be treated with surgical intervention and radiotherapy. Stage III and IV tumors are more advanced and are treated with more extensive surgical procedures, along with radiotherapy, chemotherapy, or a combination of both. Targeted drug therapy can also be used alone or in combination with chemotherapy and radiotherapy. Immunotherapy uses drugs that help the immune system fight cancer. This treatment can be an option for patients with advanced oral cancer who have not responded to standard treatments.
