Hi Anonymous,
Thank you for your question and for finding EmpowHER. With your health history, I would say you should call your doctor immediately to set up an appointment to get that right breast checked. Your doctor should be your best resource for questions and ensuring the best possible care related to your health.
Good luck, and let us know what you find out.
