I don’t know why the downvotes. Everything else being equal, more body tissues can only mean higher cancer incidence (even if the increase is small, I’m not saying it’s the main driver in the results reported).

A link between cancer incidence and height has also been reported in the past. There may be several factor at play (higher exposure to growth hormone, higher caloric intake) but it is not unreasonable to think that cell count is one of them. For things like skin cancer, it’s hard to justify that size doesn’t matter.
