Is high-grade neoplasia early cancer?

High-grade neoplasia is not an early stage cancer. However, it can be counted as a precancerous lesion. High-grade neoplasia, if not actively treated, has a very high chance of developing into cancer. Therefore, once diagnosed, it should be given sufficient attention. Clinically, surgery is normally recommended to completely remove the lesion. Cancer is essentially different from high-grade neoplasia. High-grade neoplasia itself is still a benign lesion. After surgery, the patient's prognosis is relatively good, and does not need chemotherapy, radiation and other treatments. once cancer is diagnosed, the patient's prognosis is relatively poor.
