Hi I've been called back after my first mammogram. I've no lumps or bumps. No changes in my boobs at all so this has come as a massive shock. I'm really worried as my mammogram was done by a trainee. When her supervisor came in to check her work she took one look at the screen and said ''wow'' that really scared me. She gave no explanation and I got dressed and left. Then I got a call back letter. Could it be bad even though I have no symptoms?
