I'm a 43-year-old woman who's a size 6 US. I've recently noticed that I have more fat/flesh on the right side between my breast and armpit than on the left. It is visible to people not me if I point it out. If I poke around there are no lumps, but it seems this increased fleshiness extends under the arm and perhaps even around to the back. I have no idea how recent this is, but I've recently become hyper aware of it because when I put my arms down to my sides I can feel flesh touching on the right in a way that is new unfamiliar.
I have breasts that ache around my cycle, and a family history of post-menopausal breast cancer (so I wasn't really worrying about that yet!). I have not recently lost or gained weight.
Is this one of those "bodies are weird" things or should I be in a panic? I do have a doctor's appointment scheduled, but I'm trying to brace myself for how much drama is ahead.
