Could be hormonal, but that doesn't seem the norm for menopausal women for their breasts to change dramatically wothout obvious organic cause.
Definitely get them checked out at a breast screening centre asap.....see a breast specialist, get lots of blood drawn and check out inflammatory breast cancer articles in case you fit into that category. I suggest this because I know of 3 women who have it...and it doesn't match much of the common info "out there".
Do check the pertinent forums on this site to get the suggestions you may need to get a proper diagnosis.
Let us know the outcome...I'm very interested in how you're doing.
