The likelihood of cancer after surgery for intraductal papilloma is very small. Intraductal papilloma is a benign breast lesion that mainly involves the ducts and usually has a favorable prognosis; however, if left untreated, the lifetime malignancy rate is 8-10%. Whether or not an intraductal papilloma develops into cancer in the future is dependent on a number of factors, such as the presence of atypical hyperplasia and the higher risk of multiple intraductal papillomas developing into cancer. There is no direct evidence that intraductal papilloma is directly related to invasive breast cancer. It is recommended to go to the hospital for regular follow-up, establish awareness of breast health care, learn about breast health care, learn breast self-examination, detect suspicious symptoms as early as possible and go to the hospital for examination as early as possible, so as not to delay treatment.
