Hello and I hope I can help you today.
First of all I want to reassure you that though skin changes can be associated with
breast cancer, there are many benign conditions that can occur on the breast that are much more common. You can get rashes on your breast from allergic reactions, heat and chafing, fungal infections, and other causes. The fact that a physician already examined your breasts for any other signs of cancer such as a lump or mass in the breast or armpit is also reassuring. Breast cancer only causes skin changes when it is advanced or an aggressive type that is not typically seen in young women, and it would be present for longer than 2 days. Because the doctor recommended
cortisone cream for treatment, it means your rash was some type of dermatologic condition and not a concern for breast cancer.
In general, women should begin having
mammography screening around age 40 regardless of symptoms, and should have a breast examination yearly with their gynecologic examination. If you ever feel a mass yourself in your breast or armpit, you should see a doctor for evaluation. The presence of a breast mass or lump is the most concerning finding suggestive of cancer in women of any age.
I hope I was able to adequately answer your question today and that this information was reassuring.
Best wishes,
Dr. Brown
