Recent NIH Study Finds Elevated Ovarian Cancer Risk With Long Term Talc Use in Genital Area
A National Institutes of Health study in 2025 found that women who were exposed to talc in the perineum for a long time had a higher risk of ovarian cancer
Sunday, August 3, 2025 - The National Institutes of Health (NIH) published a major new study in 2025 that raised more questions regarding the safety of personal care items that include talc. The study found that women who used talcum powder on their genitals for long periods of time had a statistically significantly higher chance of getting ovarian cancer. The study is one of the biggest studies that looks at the link between cancer and exposure to talc in the perineum. It followed the health of more than 40,000 women over several decades. Researchers showed that those who used talc on their genitals regularly were 35% more likely to get ovarian cancer than people who didn't use it. This new proof makes the case for thousands of talcum powder cancer lawsuits stronger and backs up what talcum powder ovarian cancer lawyers have been saying for a long time about the women who have been harmed.
People used to think that talcum powder was safe and good for feminine hygiene. A lot of women used it every day to keep their skin dry and stop chafing, not knowing that it could have long-term health effects. Over the past ten years, a lot of lawsuits have been filed against companies for not properly warning people about the dangers of using talc on their perineum on a regular basis. Some past studies had mixed results, but the latest NIH study is seen to be more reliable because it included a big sample size, long follow-up periods, and controlled for factors including age, family history, and hormone usage. Talcum powder cancer lawyers say that this study gives some of the strongest scientific support so far to people who think their ovarian cancer was caused by using talc. This study is likely to be seen by courts as a big step forward in figuring out what caused things in future cases.
The NIH study expands on what smaller cohort studies and meta-analyses have already found, but it is different because of how thorough its methods are. Researchers used women's health databases to find people to take part in the study. They then compared self-reported talc use with medical records, cancer registries, and pathology data. The study also identified a dose-response association, which means that the risk of ovarian cancer rose with how often and how long talc was used. This is a very important part of proving causation. To make sure they were right about the levels of exposure, the researchers did more than just ask people about their product habits and compare those answers to the availability of the product and marketing campaigns during the years each participant used it. The study did not show that using talc on non-genital areas, like the face or underarms, raised the chance of health problems. This suggests that the way you are exposed to talc is very important for your health.
