Question:
I'd like to thank everyone for their replies on my other question, but
something just occurred to me ... if cancer cells cannot "take" if
they are transferred from one person to another though body fluids or
blood, then why are cancer patients not allowed to donate blood for 5
years after surgery/chemo and an apparent cure? This tends to suggest
there is some risk. At the same time, I imagine there are many people
donating blood out there who are unaware of cancers growing within
them. Can someone then explain why this policy exists? Is it for
another reason?
Answer:
Since at least in theory a risk exists, it is sensible not to knowingly take
it. Also, I'm sure there are liability issues. If the person doesn't know he
or she has cancer, no one can be blamed for not suspecting it, but if the
blood bank knowingly gives someone blood from a cancer patient, I am sure
they could be sued.
