INSTAGRAM has restored images of nipple tattooing to breast cancer survivors who have undergone mastectomies posted by a charity after they were earlier removed in error . The Nipple Innovation Project, the UK s first for cancer tattoos, aims to empower women who have suffered from breast cancer. The charity, based at Goldeneye UK in Bingley, claims some of the charity s pictures of tattooed nipples were blocked by Instagram, with the platform messaging Your post goes against our community guidelines . The charity has previously received a number of warnings for uploading the pictures, but the project s founders say they have been left frustrated because they have been unable to speak directly to any representatives from Instagram.
