Hi. Deep breath.....
I understand your worries. I had a hysterectomy when I was just 36, it is now 11yrs later and I am still here
As for the spots, can I assume your dermatologist is doing the punch biopsy? My derm just cuts the area that is there. Pathology will speed thru if they suspect a Melanoma, at least that has been my experience.
Take one thing at a time.
Make sure you get blood work down too.
keep us posted, I will be thinking of you.
