Rowena, your doctor is wrong.  Surgery is not 100% successful.  My father,
at 80, was diabetic and had leukemia, which had been kept under control for
6 years with Gleevec.  Then there came a small spot on his neck that would
not heal.  Went to the dermatologist who said--cancer.  But it was small
enough that he cut it out in his office, under local.  

Sent the cancer away to the lab, put about 4 stitches in Dad's neck and home
we went.  There was much pain at the site for Dad, and the doctor had taken
such a large chunk out-to be sure to 'get everything'--that Dad couldn't
bend his neck.  Finally in 10 days Dad went to get the stitches out, and
everything looked fine.  

But the pain stayed and within just 3 or 4 weeks, another spot, in the same
spot, returned.  Went back and the doctor kept saying--"but, but, I got it
all.  The margins were perfectly clear."  He even went and got out the lab
report, and showed it to me.  I never doubted his word, he was a good man
and doctor.  Still--nothing is 100%.  There is no guarantee of anything, lab
tests or no.

Yep, the cancer spread and Dad passed away, in much pain, only 2 months
later.   I often wondered if I should have tried BS, but then, Dad wanted
his doctor to take care of it.
