Catching means the disease itself is contagious - it is the environment or habbit which spreads it as opposed to a cancer patient coughing on you and giving you cancer - unless radiation treatment has gone /very/ wrong through historic levels of medical malpractice.

Indefinite chaining area of effect vs just area of effect roughly.

I think you are mostly right but reality, as usual, is much more complicated than that. HPVs give you cancer.

See https://en.wikipedia.org/wiki/Human_papillomavirus_infection

Also there are other viruses that also cause cancer

See https://en.wikipedia.org/wiki/Virus#Cancer

So you very well could have a cancer patient coughing on you and giving you cancer but the underlying cause is the virus that they have (that caused their cancer) rather than the cancer itself. So you have chaining of cancer (albeit via a virus).

"The World Health Organization's International Agency for Research on Cancer estimated that in 2002, infection caused 17.8% of human cancers"
