Yes. When you remove the blood from the body and expose it to UV, you're exposing the pathogens in the blood directly to UV. When the blood is still inside the body, UV can't reach it, it's blocked by the skin. Also, that causes sunburns.

Yeah the blood irradiation approach avoids skin cancer risk by skipping straight to blood cancer!

Blood is on the inside, and skin isn't transparent to UV.
