This is inaccurate. Rumors began to circulate after an alleged photoshopped family photograph of her and children. Kate Middleton had not made a formal public appearance since Christmas Day. Shortly into the New Year, the Royal Family announced she would undergo abdominal surgery. On March 22, Middleton announced that during this abdominal surgery, her doctors found a cancerous mass and she has been undergoing preventative chemotherapy treatments and this is why she has not made a public appearance this year so far.
