The cancer time of atypical hyperplasia is mainly related to the degree of hyperplasia, treatment and individual patient factors, and cannot be generalized. In general, atypical hyperplasia may develop into carcinoma in situ within 1-2 years if there is no timely intervention, but specific problems should be analyzed. If it is mild and moderate atypical hyperplasia with mild symptoms, then 90% of patients can become normal cells after intervention or removal of causative factors. However, if the patient has severe atypical hyperplasia, it is usually difficult to reverse and can develop into cancer, only about 30% can recover, and most patients will develop into early stage cancer in about 2 years, so it should be closely observed and actively handled. It is recommended that patients should pay attention to establish a healthy lifestyle, eat a light diet, avoid spicy and stimulating foods, and avoid drinking alcohol.
