Should i be concered my mother age 57 recently diagnosed with Invasive ductal carcinoma. Mastectomy stage 1 grade 3. I noticed this mark on my Rt breast over a week ago started as a red flat dot then a few days (and got worse). Worried about IBC. However i have never had eczema before. I do recall a period of two days my nipple was sore and crusty yellow for a few days and cleared up however no issues since. Must be a local skin irritation right. this isn’t usual presentation for IBC is it? Probably just my mom hx and location that has me thinking.
