Cancer has not been overcome yet, mainly because it is prone to recurrence and metastasis, and even though it may be better controlled at the beginning, there is still a possibility that other parts of the disease may appear later. However, for some cancers, such as early malignant tumors, it is possible to cure them, that is, to achieve the effect of overcoming them. Many early-stage breast cancers do not require mastectomy, but rather breast-conserving surgery and biopsy of the anterior lymph nodes, and the scope of surgery is getting smaller and smaller. Of course, locally advanced breast cancer and other types of locally advanced malignant tumors are systemic diseases that require comprehensive treatment. There is no way to overcome cancer now, but regular health checkups, early detection and early treatment of problems will be much better.
