Intraductal papilloma, an atypical hyperplasia, is usually a pre-cancerous lesion of the breast, and the specific cause is not yet clear.
The epithelial cells in the ducts of the normal population are often affected by various factors such as estrogen level, prolactin level, age and so on, resulting in different types and degrees of hyperplasia, which are collectively called intraductal hyperplasia.
Among them, intraductal atypical hyperplasia is a common form of precancerous breast lesions, in which the size and shape of the epithelial cells in the patient’s ducts are usually not fixed, and often infiltrate the normal epithelial cells in the surrounding ducts.
Meanwhile, intraductal papilloma is also a common clinical papillary lesion, which may deteriorate into intraductal papilloma if it continues to develop, and belongs to a precancerous type of invasive breast cancer. However, the exact cause of the disease is still unclear, and it is mostly considered to be related to hereditary factors and high estrogen levels in the patient’s body.
Although the above situation belongs to precancerous breast lesions, it does not necessarily develop into breast cancer. It is recommended that the patient undergoes further examination in a timely manner to clarify the situation of intraductal epithelial cell proliferation, and then actively cooperates with the doctor to carry out treatment according to the actual condition.
