Is the risk of medium-sized surgery for liver cancer located at 37X33mm high? What is the best treatment?

Surgery is usually the first choice for treatment at present, although the risk of such a small tumor is not small. Why does it metastasize and recur after operation? Because the incision of the operation is a blind spot of human immunity, if cancer cells are hidden here, they can often succeed; The inevitable aggregation of tiny platelets during the operation protects the drifting process of cancer cells in the blood and escapes the hunting of powerful human immunity. Many metastases or recurrences are only a matter of time. Activating the body's immunity to identify cancer cells and then killing them may be a good way, perhaps the best way.
