What to expect after a Lumpectomy? I am a 32C with dense tissue, the mass is 2cm and 7cm from the nipple.

I am having a lumpectomy to remove a benign mass. I am a 32C with dense tissue, the mass is 2cm & 7cm from the nipple at 9 o'clock, do you think the breast will look noticeably different? I was told there may be some flattening in the area. What would be the best option if the results are not aesthetically pleasing? And any recommendations to help the scar fade fast? Thanks!
