Some antibiotics tied to increased colon cancer risk

the Oncology Nurse Advisor take:

Higher diversity of bacteria in the gut has been linked to lower colon cancer incidence. Researchers examining antibiotic among 22,000 colorectal cancer patients in the United Kingdom found that those taking antibiotics were 8 to 11 percent more likely to develop colon cancer after other factors were ruled out. Some antibiotics can reduce gut bacteria diversity, which might leave individuals more open to risk. Penicillin was linked most strong to this modest risk in cancer incidence.
