"Hardiness" is a relative term here. They are not going to
when dried out, subject to extremes of osmolarity or pH, or even
hand-washing. And, as other people have pointed out, they almost
certainly won't survive your immune system. (Actually it's rather
tricky to get many tissue-culture adapted cell lines to grow as a
tumor in an animal, even in an isogenic or immunodeficient

Also, IMO, most of the contamination of other cell lines is
probably due to sloppy technique.
