So no, routine blood tests don't test for cancer. And even if they could, they probably shouldn't (unless they are very, very good tests). If a person has other information - symptoms, family history,etc, this changes the base rate, and changes the interpretation of the test.
Quest Bowhunting is the brand of compound bows that are made by the G5 Outdoors Company. You will find the bows either under the brand name of Quest or else the parent company will be acknowledged in the name and the bow will be referred to as a G5 Quest compound bow.
But if your just getting into bow hunting get a single cam PSE or quest bow, they last forever and the are anywhere from 300 to 600 dollars thats just my perspective, Bear Motive 6 or 7. Bear Archery is making some awesome bows and range anywhere from $300-$900. I wouldn't shoot anything but a Bear.
