This MUST-SEE photo reveals a little-known sign of breast cancer...

We know to look out for lumps and bumps, but there are other signs of breast cancer that we’re less familiar with.

So to help us all detect the disease more easily, one courageous woman opened up about her battle with breast cancer, and the tiny detail that led her to being diagnosed.

Kylie Armstrong from California posted a photo to Facebook which reveals small dimples underneath her breast.

Concerned, she visited her doctor to get it checked, but there was no lump to be felt.

But Kylie’s fears weren’t eased. She had told her doctor that her breast had looked different to how it normally does, and after lifting her arm to reveal the dimple, she was sent for a mammogram.

That lead to an ultrasound, which unfortunately confirmed Kylie’s worst fears. She had breast cancer.

Kylie, who said that the diagnosis turned her world upside down, took to social media to take a photo of her dimples, as an eye-opener to any woman who wouldn’t normally get a slight change in their breasts checked out.

Her post has been shared almost 60,000 times.
