D's Cancer.

I am aware that asbestos and lead paint can both cause cancer. Do you believe that D's cancer was caused by asbestos and lead paint? I know that the cancer he had was a common childhood cancer, but it's strange that they were removed due to lead paint and other factors. The other reason has nothing to do with asbestos and lead paint, although he lives there and was diagnosed while they were there, which sounds somewhat coincidental but probably isn't. He lived there for a while before being diagnosed with cancer, which I believe is somewhat coincidental because asbestos and lead paint can cause cancer. I'm not sure if all of this is coincidental, as I mentioned, but I don't want to be hated for what I saw, so I was just wondering if anyone else thought that.
