Atypical hyperplasia of the breast is usually completely cured by surgical treatment. Atypical hyperplasia of the breast, also known as precancerous lesions of breast cancer, refers to the abnormal proliferation of epithelial cells, which is an intermediate stage from benign tumors to malignant tumors. Patients who go to the hospital for surgical treatment in time after discovering the lesions can avoid the cancerous transformation of breast atypical hyperplasia. Moreover, regular checkups, more exercise such as running, a light diet and enough sleep can help prevent the recurrence of breast atypical hyperplasia. It is recommended to go to a regular hospital in time when breast atypical hyperplasia is detected and receive standardized treatment under the guidance of a doctor.
