Not every case of breast cancer reveals itself as a lump, warns one woman who just received a troubling diagnosis herself.

The day after her biopsy came back positive, Sherrie Rhodes from Hull, England, posted a picture of her own symptoms on Facebook, urging other women to recognize potential warnings signs besides the stereotypical mass. The 37-year-old mom had recently noticed two dimples on her chest, and visited her doctor two days later.

Since it wasn’t a lump, Rhodes initially didn’t think much of the change, but a visit to a breast clinic proved otherwise. “I couldn’t stop crying,” she told the Daily Mail. “I’ve got three children and having to tell them something like that was horrendous.” As difficult as that experience was, Rhodes realized her pain could potentially help others.

“I decided to do the post almost straight away,” she said. “I was nervous about doing it but thought I’d do it in a delicate way and thought it would be worth it if it helped just one person.”

The picture soon took off as other women shared words of support and encouragement and thanked her for opening up. While dimpling isn’t a particularly well-known sign of breast cancer, it’s just one of many physical indications that signal something’s up.

You should make an appointment with your doctor if you notice changes in the size, shape or appearance of a breast, like a lump, thickening, redness, pitting or dimpling, according to the Mayo Clinic. A newly inverted nipple or peeling, scaling or flaking around the areola can also be a warning sign.

While it’s tempting to brush off potential symptoms, early detection can make a huge difference when it comes to treating this devastating disease.
