The patients who used the medicines for 16 days had heightened risk cancer and patients who used the drugs foe more than 60 days had low risk of colon cancer.

Further study found that antibiotic exposure was only linked with risk of only 15% for cancer in proximal colon. When individual classes of antibiotics were investigated it was found that penicillin was strongly linked with increased risk of colon cancer.
