As Catherine, Princess of Wales, announces her treatment for cancer, a look at recent events that have fuelled rumours

On Friday, Catherine Middleton, the Princess of Wales, said she is undergoing chemotherapy for cancer — an announcement that comes amid what hasn't been a good year for Britain's royals so far.

First came the “royal health shock” headlines when palace officials announced that King Charles III and Kate both had health troubles. An absence of information about Kate's health and whereabouts then fueled an increasingly frenzied rumour mill that made its way from the fringes of social media to front pages around the world.

Distrust of the monarchy only intensified after Kate admitted that she edited an official family photo, and palace officials have struggled to regain control of the narrative as conjecture and conspiracy theories persist.
