Its been 4 weeks since my lumpectomy and I went the post op bra during the day and change over to the R Bra type of a night. Initially each time I took off ANY bra my affected breast felt sore - I felt like the new adhesions were tearing or something as the book dropped to normal position. So I found it more comfortable to wear the comfy droptop type r bras. Together with the exercises I thought my poor old boobs were starting to look a bit lifted. lol. maybe not - but ill ask oncologist when I start radiation what they think. Mine are comfy and don't prevent me from sleeping - in fact may keep them more enclosed so I don't lay on them. lol.
