Months after Princess Kate announced she had been diagnosed with cancer, conspiracy theories and rumours on the royal’s whereabouts have continued to spread. One in particular has taken root on social media, with people speculating that Kate has not been sighted in the United Kingdom in recent months because she is not in the country. Instead, these people claim, the princess has been in the United States—more specifically, in Houston, receiving treatment at the MD Anderson Cancer Centre. Kensington Palace has come forward to declare those rumours false.

In an article published Monday, a spokesperson for the palace denied to the Houston Chronicle that Kate is undergoing treatment at the cancer centre. Meanwhile, representatives for the Texas facility—which is renowned for its work in cancer research and treatment, and which has treated celebrity patients like late rock guitarist Eddie Van Halen and tennis star Chris Evert—did not comment, due to patient privacy laws.

Kate last made a public appearance on December 25, when she joined other members of the royal family for the traditional walk to Christmas morning service at Sandringham.

While some tabloids have speculated on whether or not Kate will ever return to full-time royal duties again, a source told Bazaar that claims she would not are ‘unfair and untrue.’

‘There is no information about Kate’s ‘return’ because the focus at this moment in time is 100 percent on her health—to suggest she won’t return to her role is unfair and untrue,’ the source said. ‘Conversations of that nature are just not being had. When the time is right, she will resume her work.’

Kate personally announced her cancer diagnosis in a video message posted on social media on March 22. ‘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,’ she said in the clip. ‘As I’ve said to them, I am well, and getting stronger every day by focusing on the things that will help me heal, in my mind, body, and spirits.’

While the type of cancer and the stage it has progressed to have not been specified by the palace, the princess did say in the video that she is in the ‘early stages’ of ‘preventative chemotherapy.’
