Can inverted nipples lead to breast cancer?

Nipple inversion is a relatively common breast condition, and does not necessarily indicate breast cancer. However, inverted nipples are more prone to bacterial or viral infections, and patients with this condition are at a relatively higher risk of developing breast cancer. The details are as follows:

Breast cancer is a malignant tumor caused by uncontrolled proliferation of breast epithelial tissue under the influence of various carcinogenic factors. Its exact cause remains unclear, but it is generally considered to result from a combination of hormonal influences, genetic factors, radiation exposure, psychological stress, environmental factors, and lifestyle. Nipple inversion refers to the condition in which the nipple retracts into the areola, which is mostly due to congenital factors, trauma, inflammation, or tumors. While nipple inversion itself does not directly cause breast cancer, persistent inversion makes the area difficult to clean and may obstruct lymphatic drainage in the breast, increasing susceptibility to invasion by bacteria, viruses, and other pathogens. Therefore, it is considered one of the risk factors for breast cancer.

Nipple inversion usually cannot resolve spontaneously and requires active treatment. Therefore, individuals experiencing nipple retraction should seek timely medical evaluation. Under a doctor's guidance, appropriate treatments such as manual stretching, suction therapy, or surgical correction can be used.
