This content is copyright of CelebMix.com. Strictly Come Dancing star Amy Dowden has joined forces with Gemma Ainger to launch a new app called My Breast Friend. The app's mission is to help people check in with their bodies. Simple, supportive, and completely free, the app sends a monthly reminder to perform a self-check and lets users log any changes quickly and privately. The tone is warm, positive and stigma-free - because checking your boobs, chest or pecs shouldn't feel scary or clinical.
