Although the current medical technology has been relatively developed, cancer is still a difficult problem in medicine. The cost of cancer treatment is high, and there may be Let patients bear greater pain, so cancer has always been called an incurable disease in people’s minds.

Based on the current situation, cancer is not enough to be called an incurable disease, because early and mid-term detection Under the premise of cooperative treatment, cancer can generally be conditioned and improved accordingly. People have seen many cases of cancer recurrence after being cured in daily life.

Is clinical cure of cancer not equal to complete cure?

The condition of the patient can be controlled and improved after treatment of the cancer detected in the early and middle stage, so people usually call this situation It is called “healed”.

However, some people’s cancer is obviously cured, but it still recurs after a period of time. Aspect healing is not exactly the same as absolute healing.
