The initial urgency with Jill's tumor was the doc's concern that it was originating from her ovary (which can be very painful and life-threatening).
Further testing revealed that her ovaries weren't affected and it wasn't a "singular" 40# tumor, but multiple tumors that were endometrial in origin--hence, no urgency, not life-threatening.
Jill was told that it would be better to lose some weight before she had the surgery. All that adipose tissue would make healing difficult. The doc's also gave her drugs that would shrink the tumors somewhat, making it a little more comfortable for her while she lost weight.
Last report I heard was Jill had lost 60 pounds and had not yet had the surgery.
