Rash right breast

Hello. My name is Sarah and I am incredibly appreciative a site like this exists. I have an extensive family history of breast cancer. Approximately 3-4 weeks ago, I developed a circular, red, itchy rash on my right upper outer breast. It looks much like ringworm, though I have no idea how I could have been exposed. I supposed anything is possible but it’s also an odd place for it. My PCP is treating me for ringworm and will do Lyme testing in a few weeks as well. I think my question is since the rash comes from the lymphatic system being clogged in IBC if an anti-fungal cream with a steroid would help clear it up. I missed a few days of the cream and it erupted again. I know the fungal part wouldn’t help, but am wondering if steroids would help clear the rash and if a response to the steroids is a positive sign this is not cancer. Next step is OBGYN.

Hi becominglola

Thank you for your post about the red itchy rash you have recently developed on your right breast. We are not able to comment on any photographs or to recommend specific medications or creams.

Breast changes can happen for many reasons. They may be due to hormonal changes as part of your monthly cycle (if you are still having periods) or due to benign conditions (not cancer). For more information see our booklet Know your breasts: a guide to breast awareness and screening.

If your rash is not improving, then it is important to return to your GP for further assessment. They can review you and may refer you to either a dermatology or breast clinic if required.

It is understandable that you have questions about your rash and whether it may be a sign of breast cancer, especially as you have an extensive family history of breast cancer. Having a family history of breast cancer does not automatically mean you are at a greater risk of developing breast cancer in the future.

Most breast cancers are not inherited. There are only a small number of people who will be at a greater risk of developing breast cancer because they have a significant family history. The biggest risk factors for developing breast cancer are being a woman and increasing age.
