A new campaign from Peru's League Against Cancer takes an original approach to encouraging women to get breast cancer checks: it features pairs of boobs arguing with each other.

In each of four wittily-scripted spots by agency Circus Grey, a well-known Peruvian actress plays both left and right mammaries, having conversations with each other over whether to get a breast check. (In each, one breast is relaxed or thinks it doesn't apply to them, while the other is more cautious.) The actresses—Patricia Portocarrero, Leslie Stewart, Ebelin Ortiz, and Anaí Padilla—each bring a subtly different vibe to the dialogue, but each ends with the same message—don't keep make excuses not to go.

The campaign, directed by Bacha and Chinon at Señor Z, taps into the insight that the main reason women in Peru don't go for preventative exams is that they fear the results. Breast cancer is the most common cancer in Latin America and the WHO predicts that cases will rise by 64% by 2040 if rates continue to rise.
