I did not do any preparation for the lumpectomy.  A lumpectomy is nothing more than a biopsy. They just take out a bit more. My surgeon took out 5 millemiters of normal tissue surrounding the tumor to ensure there were no cancer cells floating around.  I had a sentinal node biopsy as well. Recent results from studies indicate it is not necessary to take out more than 2 lympnodes.  I hope that is all they are taking out.   Again, it is a small, thin inscision. I was absolutely fine after the procedures and did not require any pain medication. I also felt all kinds of pains after diagnosis.  I believe it was phychological as i did not experience any pain until they diagnosed me. 

I would not compare a biopsy to that of a lumpectomy.  A biopsy takes various small pieces of tissue to examine. If a lumpectomy is required then there is a margin of tissue removed around the mass to ensure clear margins. It also depends on the size of the mass and where it is situated in the breast. 

I would suggest that you ask your breast care nurses for advice on bra etc and sleeping supports. I found a soft bra and a small pillow to support my arm helpful as the lump in my breast was near the cusp and close to my armpit. As I say nursing staff will support you.

i remember being advised by the surgeon and oncologist not to use anything other than that recommended by them.   If you need a mastectomy again you will be advised by medical staff. Two lumps suggest you may well need a mastectomy but medical staff will make decisions in need. Take care WA

I hope your surgery went well I had lumpectomy and 3 nodes removed mine was done as a daycase  patient due to position of tumour I had one cut under my arm I was being treated for breast cancer grade 3 triple negative but found out I had a breast lymphoma and I have diffuse B cell non-Hodgkin's lymphoma good luck with your treatment xxx
