A breast cancer selfie is going global. A woman from Manchester, England says she took the picture earlier this month and decided to post it online in hopes of showing women the warning signs.

So far, it has more than 75,000 shares. Lisa Royle posts that she found very subtle dimples on her breast that could easily be missed by women.

According to CBS News, skin dimpling can be a sign of cancer.

Lumps or masses on the breast are also the classic warning signs.
