Celebs Are Posting Nipple Pics To Raise Awareness For Male Breast Cancer

Samuel L. Jackson is the guardian of male boobies as a spokesman for the One For The Boys organization, which urges men to keep their eyes out for signs of male breast cancer.

In a PSA for the organization's new #InTheNipOfTime campaign, which asks men to share supportive, awareness-raising tweets and nipple pics with the hashtag, Jackson reminds dudes everywhere,

Men don't just get man boobs. They can get breast cancer too, so when you're thinking about copping a feel, cop a feel of yourself.

The 66-year-old tweeted a photo of his own nipple for the cause.

Mark Ruffalo also lent a nip.

Rugby player Jim Hamilton tweeted a romantic black-and-white nip shot…

…and convinced fellow players to send theirs along.

One For the Boys reports that every year, more than 70 men die from breast cancer, a disease that most commonly affects women.
