Do family histories of different cancer types overlap?

[uq_civediv]

i think we've all seen studies saying that having relatives w/ say, breast cancer increases your chances of getting it too.

is there data on overlap between different types of cancer, like having a close relative die of colon cancer influencing your chances of developing lung cancer ?

or genotype data; gene variants affecting various cancer types

intuitively there should be overlap, both in pedigree and genotype data, i just don't remember seeing any lately

any references/comments?

i know of this one because of someone i know online that recently died of rectal cancer. I'm sure there's other examples out there.
