<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a dimple on my breast. It did not show up on my last mammogram. My primary care doctor said she does not think it could be cancer, but I have been doing my research and am concerned that I need more tests to determine what exactly it is. Can you please advise me on what tests I should request my doctor to run?  <response>: Hi ! Good afternoon. I am Chat Doctor answering your query. As per your history, you need a detailed physical examination by a general surgeon of the breast and maxilla. Apart from that you should also go for a repeat mammogram me. If all are normal, then it needs close observation, and might need an excision biopsy in case of increase in size. I hope this information would help you in discussing with your family physiciantreating doctor in planning your treatment. Thanks for using the Chat Doctor forum for your query on health. Wishing you an early recovery. Chat Doctor.
