Hi I'm new to this forum just looking for any advice. Iv found what feels like a hard area just under my right breast im not sure if this is in my breast or top of my ribs it's definitely different to the left side. Can't see it just feel it. I've had mammogram few years ago due to pain in right breast all normal said hormonal changes. I'm just wondering should I get it checked I will feel silly if it turns out just to be muscle or part of my ribs. I'm 45
