GOOP, the lifestyle blog from actress Gwyneth Paltrow, recently published an article on a long-discredited claim that there could be a link between wearing bras and breast cancer. Though they cited research that has been dismissed as false by The American Cancer Society, Paltrow and her brain trust over at GOOP decided to post the piece during Breast Cancer Awareness Month. The author of the post, Dr. Habib Sadeghi, offers as evidence the book Dressed to Kill: The Link Between Breast Cancer and Bras, written in 1995 by Sydney Ross Singer and Soma Grismaijer, a husband-and-wife team of medical anthropologists.

Dr. Habib Sadeghi is a freelance blogger.

The quackery begins by talking about how bras restrict the lymph nodes:

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. Accumulated toxins anywhere in the body increase the risk for cancer. 

Nope. The American Cancer Society says any theory that breast cancer is caused by an accumulation of toxins due to restricted lymph node drainage is “inconsistent with scientific concepts of breast physiology and pathology.” This is in line with statements from the Susan G. Komen Foundation and But the good doctor isn't done yet! Apparently breasts aren't supposed to get too warm:
