Pain in one breast (mastodinia) maybe is not typical for breast cancer but still you need to have a clinical examination (inspection and palpation) and echo or mammography scan to exclude hidden breast cancer. Presence of eczema should be taken seriously until the breast cancer is excluded. Certain types of breast cancer are indicated with skin manifestations similar to eczema.


Pain in the breast could be due to infection, trauma, muscle pain, or arthritis under the breast. Breast pain is often connected with menstrual cycles but that is excluded in your case.
