My guess is that we all have predispositions to developing certain types of cancer....consider the medical histories of your grandparents, parents, and siblings for (approximate) guidance...

Your grandparents and parents provide a good real-world "preview" of the possibility(s) that genetic make-up might predispose one to certain infirmities, illnesses, cancers...

Maybe you should be on guard against those evidenced, to the extent possible...after all, you're very much like them...?

Did they live a life that eventually led to any medical conditions they experienced...?

Should you avoid the life choices that they made...?
