Can the eczema on my nipple become cancer in the future?

I'd check with a . Breast surgeon to be sure "eczema" is not bowen's disease, and check for lumps, you are too young for 'screening mammo, " but if there is abnormal finding by an expert, these are next steps. I cannot tell on the on internet about a physical finding.
No. Eczema is not a precancerous condition and cannot turn into cancer. However, there is a form of breast cancer called paget's disease that presents with an eczema-like skin change at the nipple. The only way to distinguish the two is by biopsy; this can be performed under local anesthesia in an office setting.
