This is Dr. David
it sounds like your doctors are very worried about leaving residual breast cancer in your breast.
some breast cancers are multifocal and in the initial lumpectomy specimen, multiple sites of breast cancer are seen.
this means there is a very very high chance that there is more large amounts of breast cancer still left in your breast.
in these situations, lumpectomy and radiation has been shown to have a worse control of the breast cancer compared to mastectomy.
if the breast cancer is in only one location and there is a slight positive margin, then yes, you can have lumpectomy and radiation therapy and not have mastectomy.
I would get a copy of the pathology report from your lumpectomy procedure.
I would be very happy to review it with you and let you know if you need a mastectomy or not.
Hi Dr David,
Thank you for replying. Just to add to what I said earlier, when the margin was not clear my surgeon said that the majority of the tumour was removed with only a tiny amount left at the "8 o'clock " position.
A cavity shave followed to gain clearance, which was only going to be a 20 minute or so operation. This is why I have asked about radiotherapy to clear up what may be a tiny amount of residual cancer rather than undergo more bigger surgery and then reconstructive surgery on top?
