What is considered as cured cancer? Clinical cure can be defined as long as the original symptoms and tumor disappear after treatment. According to clinical practice and follow-up observation, many patients with cancer have been cured. If there is no recurrence of cancer for 5 years after treatment, it is possible to be cured permanently. This is because only a few percent of these patients will have further problems in the future. According to the above criteria, a significant proportion of cancer patients are cured. The 5-year survival rate of nasopharyngeal cancer after treatment is 54%, and the 5-year survival rate of cervical cancer is 60-70%, so that cancer can be cured with reasonable treatment.
