IARC study links one in eight cancer cases to infections
A study by the International Agency for Research on Cancer (IARC), published in The Lancet Oncology, indicates that approximately one in eight cancer cases globally is linked to infectious agents such as viruses, bacteria, or parasites.
In 2024, an estimated 2.3 million new cancer cases were attributed to these infections. Key contributors include Helicobacter pylori, which is associated with roughly 760,000 cases, and the Human papillomavirus (HPV), which was linked to approximately 750,000 cases. HPV is noted as the cause of more than 90 percent of cervical cancer cases.
Researchers emphasize that while these infections are significant drivers, not every infection leads to cancer; factors such as lifestyle, genetics, and immune system strength also play critical roles.
