An online post about the myth that wearing too-tight a bra may increase the risk of breast cancer has actress Gwyneth Paltrow in hot water.
The claim appears on her lifestyle blog Goop.com, CBS News reported.
"Among those who acknowledge the bra/breast cancer risk connection, it's widely held that a tight-fitting bra restricts the lymph nodes around the breast and underarm area, preventing toxins from being processed through them and flushed out of the body," Dr. Habib Sadeghi writes in the post.
"Accumulated toxins anywhere in the body increase the risk for cancer," Sadeghi claims.
However, the American Cancer Society and other major medical groups say there is no proof to support the theory, which circulated on the Internet last year, CBS News reported.
"We do not know of any epidemiologic studies published in scientific journals that suggest bras directly contribute to breast cancer risk or that lymphatic compression by bras might cause breast cancer," the American Cancer Society says on its website.
While the post wasn't written by Paltrow, the fact that it appears on her site represents her stamp of approval, CBS News reported.
