dont worry. Doctors are very smart, and well supplied, and can pretty much do anything these days. I had an aount go in for brest cancer, and a cousin go in for testicular cancer. Very very hard time for the family (9 aunts and 24 cousins on my side*), but everything went fine. After my cousin was cured he decided he wanted to go to Med School, and he is graduating this year.
Your family is my prayers.
*my grandparents had 9 daughters, no sons. And those 9 aunts had 24 kids, 22 are boys
