I am glad that your are seeking medical advise for your problem.
The lesions which you are explaining do seem to be infectious in nature and can be a staph infection which is known as folliculitis
. If the cream is not providing you any relief, you should consult a dermatologist
or a infectious disease doctor and they will give you oral antibiotics
. Some people are carriers of this infection and that is why they get it repeatedly. Your doctors can do some tests (like nasal and pharyngeal swab) to check for that.
As far as breast cancer
is concerned, your lesions dont fit into the picture. Breast cancer usually presents as a painless lump in the breast
. It can also be detected on screening mammographies. If you have a family history of breast cancer, it is advisable that you visit a surgeon every 6 months for a breast examination and get annual mammograms or sonomamograms done.
Hope you get well soon.
