The list of chemicals that are suspected carcinogens is ENORMOUS. You would not touch anything or go anywhere if you tried to avoid all suspected carcinogens.
Same goes for foods. Some are meant to be good for the heart, but may cause increased risks of certain other diseases. If you avoided all food that could cause any disease you would not eat much!
If anyone wants to give away any fishing or boating gear that is suspected of being carcinogenic, I will gladly offer to dispose of it for you.
