You may start to see women upload photos online with smeared lipstick.

The reason? It's part of a new campaign called #SmearforSmear, aimed at raising awareness as Cervical Cancer Awareness Month concludes.

Decidi borrar meu batom por uma boa causa! !! "Segundo a sociedade americana do câncer, nos últimos 30 anos, a taxa de mortalidade por câncer do colo do útero tem caído mais de 50 por cento, devido ao aumento do uso do exame Papanicolau." #Smearforsmear #JosCervicalCancerTrust #womenUnite #GetTested #SaveLives #Awareness #Prevetion #Lipstick #red #smear #selfie

Started by the U.K. group Jo's Cervical Cancer Trust, the campaign highlights the importance of women getting smear tests. According to the organization, such tests save thousands of lives each year.

The campaign works by asking individuals to share a photo, then nominate friends to do the same.

“My sister Natasha Porter beat cervical cancer and will be three years all clear in May," participant and actress Kirsty-Leigh Porter said. "I can't stress how important it is for girls to attend a smear test. It saved my sister’s life. It could save theirs.”

Ladies, please pay more attention to your health conditions. #smearforsmear
