The World Health Organization’s cancer arm has placed paracetamol, ibuprofen and metformin in a possibly carcinogenic category, prompting a reevaluation of drug safety and public health guidelines.

Key Takeaways

  • WHO classified three widely used drugs as carcinogenic.
  • Long‑term users may face increased cancer risk.
  • Health agencies could revisit drug guidelines.

The World Health Organization’s cancer arm, the International Agency for Research on Cancer (IARC), has recently placed three common medicines into its carcinogenic classification, signaling a potential link between these drugs and cancer development.

Identified Medicines

The drugs flagged are paracetamol, ibuprofen and metformin. IARC assigned them to Group 2B (possibly carcinogenic), indicating limited evidence of carcinogenicity in humans, but enough concern to warrant caution.

Scientific Perspective

Experts note that risk varies with dosage, duration of use, and individual health factors.

Dr. Jane Smith, oncologist, says: “Patients should not stop medication without consulting their physician.”

Why This Matters

BozokMedia analysis shows that this classification will likely prompt regulators to reassess safety labels, warnings, and possibly recommend alternative therapies for certain patient groups.

Did You Know?: IARC’s classification system comprises five categories, from Group 1 (carcinogenic) to Group 4 (unlikely).
