Recent studies have examined what tampons are made of and whether those materials might pose risks — but so far, there is no confirmed link between tampon use and cancer.
A 2024 study examined tampons from multiple brands and found trace amounts of certain metals, including lead, arsenic, and cadmium. These metals were detected in all the products tested.
However, the study did not measure whether these metals are absorbed into the body through tampon use or whether they are present in amounts that would cause harm.
The researchers noted that more investigation is needed to understand potential health effects.
In 2025, a report from the Pesticide Action Network UK found that some tampons sold in the UK contained glyphosate, a chemical used in herbicides (weed killers).
Glyphosate has been the subject of debate regarding its cancer risk, mainly in the context of agricultural exposure. The report did not establish a health risk from tampon use, but it added to the call for more transparency and testing.
At this point, no studies have shown that tampons cause cancer. The presence of certain substances in tampons does not necessarily mean they are harmful in this context.
What remains unclear is whether, and to what extent, these substances might be absorbed through vaginal tissue over time.
Regulatory agencies, including the Food and Drug Administration (FDA), are reviewing the latest findings and may conduct further studies.
In the meantime, you may reduce potential exposure by selecting tampons from brands that disclose their materials, avoiding fragranced products, or switching to other options like pads, cups, or discs.
Staying informed and making mindful choices can help protect your health as science continues to evolve.
