Cancer is a generic term for a large group of malignant tumors, and the treatment of cancer in general speaks of a five-year survival rate. If there is no recurrence for more than five years, it is considered to be clinically cured. However, it cannot be said to be completely cured, because there is still a possibility of recurrence, but after five years, the chance of recurrence may be much lower. If you can survive for more than 10 years without recurrence, the result is even better, and you can basically be considered cured. It is possible to survive more than 20 years, 30 years or even longer afterwards, which means that it does not affect the survival period. Cancer generally needs to be detected and treated early for better results. Early radical treatment through surgery and post-operative integrated anti-tumor treatment such as radiotherapy and chemotherapy can possibly make the cancer achieve a cured effect.
