I'll chime in also. My MO made a point to say I probably was exposed in my early 20's, was contagious for a bit and didn't know it, my body finally killed it off and I've lived my life to now being neither contagious nor able to contract it again. The main point he made was trying to figure out who I got it from or who I may have passed it to is fruitless in a world where >80% of the people in our demographic have been exposed.

I know you said you feel you have a moral conviction about telling but there is no screening available to tell if you'll get this cancer. You just do one day for reasons that are still unclear. Also, you have no way of ever knowing if you were the one who transmitted it and quite frankly you may not have anyway.

Like others have said: focus on the next several months of YOUR life. This is the most important thing you can do right now.

Best,
