I had big boobs as well! No one could feel my tumour it was so deep. It was picked up in a routine mammogram.
Yes, it is very confronting losing that part of your body. Femininity, motherhood, shape giving, erogenous, sexuality. To the exterior world they are so defining of us, and personally, such a source of so much intimate identity. But we are not our breasts.
I have this opinion that why a diagnosis of BC is often more traumatising than other cancers is because the treatment of it is so often highly visible, and so visibly associated with what is regarded as a fundamental femininity. You can lose parts of your insides to cancer, sections of bowel, your thyroid, but the world does not see or care. You don't see.
None of these thoughts are shallow. I was still menstruating when I was diagnosed at 51 and I deeply resent being slammed into a hard menopause. This BC shiz is hard! On many levels. Don't castigate yourself for any of these thoughts. We all have them. Be gentle with you. K xox
