The lesion is removed from the body before it converts into Cancer I Malignancy. Many colon cancers can be prevented by removing precancers lesions like polyps before they become malignant. In a preventive medical procedure, the specialist removes tissue that doesn’t yet contain disease cells but is likely to become carcinogenic later. This may likewise be alluded to as a prophylactic medical procedure. For instance, with the patient’s consent, the specialist sometimes removes a lady’s ovaries to avoid the risk of malignant ovarian growth and chance that the individual has an imposing family background of ovarian disease. Because of studies, a lady whose mother or sister had ovarian disease has a higher than usual chance of creating malignant ovarian growth. The method is called prophylactic oophorectomy (evacuation of the two ovaries).
