Ambra,
When I first this post, I did not have a position on this but after reading Karen's post, I was reminded of the fact that a very high percentage (I think higher than 50%) of people get the
HPV virus along the way.
The issue is not getting it, the issue that very small percentage of us who do not clear it and it fires off the cancer.
The odds you passed it to them and they were also in this very small club is statistically really remote. So, I think it could only get a lot of feathers flying by doing what you were thinking.
Let it go and get ready for the wild ride to come with rads. There is lots to do to stay on top of it. take care don
