However, not all cancers have a very poor prognosis. Some cancers have a better prognosis, commonly known as “happy cancers”, which generally refer to cancers with slower progression, better prognosis and longer survival time. The typical representative of “happy cancer” is thyroid cancer, especially papillary thyroid cancer, which has a 10-year survival rate of over 90% after surgery, and only a small percentage of patients will have recurrence. Of course, besides thyroid cancer, the following types of cancer also have a better prognosis: 1. nasopharyngeal cancer: nasopharyngeal cancer is more sensitive to radiotherapy. The prognosis is closely related to the disease process and stage, the earlier it is detected, the higher the survival rate, the early 5-year survival rate of breast cancer can reach 95%, which is a better prognosis; 4. Prostate cancer: prostate cancer grows slowly, the 5-year survival rate of early limited prostate cancer is above 95%; 5. Testicular cancer: the cure rate of early testicular cancer is above 95%, which is one of the best malignant tumors in terms of treatment effect; 6. Cervical cancer. The 5-year survival rate of early cervical cancer can reach 93.4%, and the earlier the stage, the higher the cure rate; 7. Hodgkin’s lymphoma: clinical cure can be achieved through chemotherapy, and the early 5-year survival rate reaches 94.3%. Patients note that even if the cure rate of such cancers is high, regular post-operative review is needed to ensure timely detection of metastasis and recurrence, which can help prolong patients’ survival period.
