When this occurs, this will grow the cell out of control, yet if the initial trigger is removed his unnatural growth normally produces a mass, thus the tumor is formed. Benign tumors comprise osteophytes, uterine fibroids, and melanocytic nevi which are restricted and limited and do not convert into cancer but Potentially malignant neoplasms constitute carcinoma in situ. which are limited, do not invade and finish but in the future, they may convert into cancer.
