What are the differences between gyne & breast cancer surgery/surgeons

[Raider Fan]

Doctors (or anyone else with knowledge),

Just wondering about some things and thought I'd ask the questions here.

1.  Does all gynecomastia tissue look pretty much the same?  I was just wondering if someone had a tumor (benign or malignant), would that be something that would be immediately apparent?  What would you do in that event?  

2.  Have you, personally, ever done gyne surgery and found that someone had a tumor, in addition to their gynecomastia?

3.  If, in the course of doing gyne surgery, a tumor WAS found unexpectedly, what would you do about it?  Would you remove it?  Or, would you leave it in, discontinue the surgery, and call an oncologist?  

4.  If you removed the tumor, would you have it tested immediately to determine if it's malignant?  

5.  After you remove gyne tissue, is THAT tissue tested at all to make sure there's no malignancy, or is the tissue simply disposed of without sending it to a lab?  

6.  When women have biopsies and surgery for breast cancer, what kind of surgeons do THEIR surgeries?  Are they general surgeons or are they plastic surgeons?  If they are NOT plastic surgeons, do general surgeons typically leave the chest looking in bad shape after removing tissue and/or performing a mastectomy?  

7.  Do plastic surgeons do mastectomies?  If not, who does, and are they concerned with the way the chest will look after surgery?

8.  If general surgeons typically do the surgeries on women with breast cancer, is it a common thing for their chests to basically look mangled after the surgery?  If so, who goes back in and makes things look better, the general surgeon, or is that only a plastic surgeon?

9.  After women have a mastectomy, who does breast reconstruction (boob job) surgery on them later on?  Would that be a general surgeon, or is it always a plastic surgeon?
