<s>[INST] I found a lump in my breast just under the areola this morning. It is hard and seems to be about a half inch long. I am 45, 5 2 and a 126 pounds. I am scheduled to go to training out of town this week for work. Should I back out of the training and make an appointment with my doctor instead? [/INST] Welcome to Chat Doctor .1. If you have only noticed for first time you don't have to rush immediately to the doctor. Wait and see for a week if it's just a cyclical changes seen in the breast.2. If you feel it's there for some time - then It's worth to rush.3. The sequence of procedure will be a mammogram followed by or correlative ultrasound breast to identify any lesions in the breast.4.
