Basal cell carcinoma is a type of skin cancer, and the prognosis of basal cell carcinoma is relatively better than that of squamous cell carcinoma. Because oncologists always tell patients that skin cancer may be the only curable cancer, of course, provided that it is relatively early and cannot be cured even if it metastasizes throughout the body. The smaller the tumor is, the less destructive the surgery is and the better the postoperative cosmetic effect is. If the tumor grows to the corner of the eye, back of the ear, or inside the nasal cavity, which is more difficult to operate, or the patient is too old and unwilling to operate, radiotherapy can be chosen. If it is an early tumor, radiotherapy can also achieve the effect of radical cure. Unless the tumor breaks down and forms a larger trauma, the effect of radiotherapy may be relatively poor, and surgical treatment with flap repair is needed. After all, the tumor should be removed thoroughly, and the more thoroughly it is removed, the better the prognosis. Basal cell carcinoma usually does not metastasize, so after surgery, people do not go too concerned about it like other cancers, and they do not need to do regular imaging examinations such as ultrasound, which can be found on the body surface by themselves. The doctor will explain the patient to observe regularly by himself, and when he feels that there is a skin bulge, he can go to the hospital to let the surgeon look at it, and if further treatment is needed, he can redo the surgery.
