Cancerfonden's video featured animated women with their breasts represented by pink circles, showing ways to detect suspicious lumps.
The images were considered "offensive" by the social media platform.

It later reversed that decision, allowing the publication of the iconic picture which shows a badly burned girl fleeing a napalm attack during the Vietnam War.
