In 2015 I noticed a dimple on the underside of my breast. It was more noticeable when I lifted up my arm. I saw my GP and was referred for a mammogram and results said no concerns and I was discharged. 7 years on the dimple is still there and when leaning over I can notice the dimple as my breast is slightly mishapen. Should I get this looked at again? As I have had it for 7yrs with no other symptoms I am thinking it's nothing to worry about.
