Princess Kate, King Charles have cancer: A timeline of the royal family's biggest moments

After a challenging few months for the British royal family – which included King Charles III's cancer diagnosis, Princess Kate missing from the public eye following a surgical procedure and being embroiled in controversy after admitting to editing a family photo – the latest blow landed Friday as the Princess of Wales announced she was diagnosed with cancer.

Though she is "well and getting stronger every day," Princess Kate revealed that "it has taken us time to explain everything" to her and Prince William's three children.

The revelation, which she called "a huge shock," made an impact on Britons and people around the world.

We look back at the biggest events the royal family has experienced over the past century.

March 22: Princess Kate reveals cancer diagnosis, 'preventative' chemotherapy

On March 22, after Kate's lack of public appearances for nearly two months caused weeks of social media furor, the Princess of Wales appeared in a video shared by Kensington Palace to reveal she had been diagnosed with cancer and was undergoing preventative chemotherapy treatments.

"In January, I underwent major abdominal surgery in London. And at the time, it was thought that my condition was non-cancerous," she said. "The surgery was successful. However, tests after the operation found cancer had been present."

She continued, "This of course came as a huge shock and William and I have been doing everything we can to process and manage this privately for the sake of our young family. As you can imagine this has taken time. It has taken me time to recover from major surgery in order to start my treatment.

"But most importantly, it has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them and to reassure them that I’m going to be okay."

The princess said she was "well and getting stronger every day by focusing on the things that will help me heal in my mind, body and spirits."
