I often chat with taxi drivers when they hear that I am a doctor, and they will ask, “So there is still life after cancer?” I would tell them, “This is an old idea, although it is cancer, as long as the lesion is found early, it can be cured.” For example, some cancers, including thyroid cancer and breast cancer, have a high rate of early detection, a high rate of early surgery, and very good surgical results. Patients with thyroid cancer live for years and decades, and some even have bone metastases and can live for a long time. The main treatment for thyroid cancer is surgical resection and lymph node dissection, because thyroid cancer is not particularly sensitive to radiotherapy and chemotherapy, and some of the patients do not even need surgery but just observation. Comparatively speaking, more and more patients are detected at an early stage, one is that people are more and more aware of medical checkups, so they go to check if there are nodules on their necks, and another is the popularization of ultrasound, including ultrasound of the neck, which can detect small nodules in the thyroid gland and then deal with it in a timely manner. Breast cancer is also a cancer with relatively good surgical results, and in addition to checking the breast, ultrasound and molybdenum target are powerful tools for the early detection of breast cancer. Anyway, the early survival of breast cancer is very high nowadays, with routine mastectomy and lymph node dissection, and nowadays there are more people who choose to conserve breasts and then do partial mastectomy or breast reconstruction in order to pursue a higher quality of life. As long as you have this awareness, early detection and treatment, you will not only spend less money, but also be cured in the end. On the other hand, if you wait until you have symptoms and metastasis before going for treatment, and then do radiotherapy and chemotherapy, you will spend a lot of money. If people are in pain and cannot be cured, they will be hooked up with the hospital in this life. Take lung cancer as an example, the five-year survival rate of stage I, that is, the earliest stage of lung cancer, can be more than 90%, but the overall five-year survival rate of lung cancer worldwide, including stage I, II, III and IV, is only 15%, which shows that the treatment effect of late-stage lung cancer is very poor, and most of the lung cancers are detected in the middle and late stages. If it can be detected and treated at an early stage, I wonder how many lives can be sustained and how many families can be saved from cancer.
