Talcum powder, which is used in baby powder and other makeup products, has been linked to an increased risk of ovarian cancer.
Talc is made of hydrated magnesium silicate and is sold globally for personal hygiene use. But many have speculated that the mineral promotes certain disease, like cancers of the ovaries and lungs.
A new Science World Report confirmed that women who regularly use talcum powder have a 24 percent higher chance of developing ovarian cancer.
Brigham and Women's Hospital doctors gathered data from eight different studies to publish the latest study.

It consisted of a group of 8,525 women who were diagnosed with cancer and 9,800 who didn't have any history of cancer.
The doctors noted that those who regularly applied talcum powder after bathing had an increased risk of developing ovarian tumors. They mainly focused on talcum powder used in the genital area.
The powder causes inflammation in the lower genital tract. This eventually moves to the pelvic lymph nodes and creates immune interference.
All women are at risk for ovarian cancer, particularly those who are over 40. The highest persistence of the disease occurs for those who are over 60.
About 20,000 women are diagnosed with the disease each year.
Doctors also found that talcum powder is extremely harmful if it is inhaled, as aspiration pneumonia or granuloma may develop. Trouble breathing can be caused by long-term inhalation of the dust.
