I don't eat processed meat and excercise daily. I like my odds even with coffee. I was briefly involved in a personalized cancer medicine company and talked to the prof there. He said if you don't smoke, avoid bacon and walk/run a few times a week you have essentially done everything you could. The bacon thing made me curious and it turned out almost all processed meat has nitrite (nitrosamine) added, which is a carcinogenic element. So much so they in fact used it to induce cancer reliably in lab rats. As to why food industry uses it - it is still better than botulism. As of 2021 we still don't have effective meat preservatives. "Rats fed dimethylurea and 0.3% sodium nitrite for 36 days developed tumours of CNS, heart, thymus, kidney or thyroid in all animals (Sander, 1970)." http://www.inchem.org/documents/jecfa/jecmono/v05je15.htm http://www.inchem.org/documents/jecfa/jecmono/v05je15.htm
