I had the “orange “ appearance and some hardness post lumpectomy surgery and then radiation didn’t help either.I visit a,good breast cancer physio and have massages of breast tissue (theyll show you how to do,it too). The orange skin appearance has abated nicely and whilst hardness and soreness isn’t greatly improved I suspect it’s leftover side effects now and I’ll have it forever .
Physio can also rule out true lymphoedema of the breast as diagnosis
other treatments included getting a piece of mobiderm and inserting it in between bra and breast tissue . You can also,wear compression bras (various ones available )
I asked surg team about mine too ( scar tissue and edema/hardness ) but they were not concerned nor bothered to give any advice so physio best source. I did have a ultrasound and mammogram 15 month post surgery to establish no recurrences.(Im stage 4 but know now that no serious cancer issues in breast tissue)
I’ll try and put some pics up for you .
