Kate Middleton joins Prince William, King Charles in her first formal appearance after cancer treatment | See photos

Things are turning normal in the Royal family, as Kate Middleton is returning to her public duties following cancer treatment earlier this year. The Princess of Wales joined the Prince of Wales, William, and King Charles at a Rememberance event in London on Saturday.

The program marks her first formal appearance since finishing her chemotherapy. Kate Middleton had announced her cancer diagnosis in June this year. The announcement came as a major setback for royal fans as King Charles III was also undergoing treatment for a rigorous cancer treatment. However, Kate Middleton's return to public duties shows her improving health.

Kate Middleton attends event in London

Kate arrived for the Festival of Remembrance at London's Royal Albert Hall wearing a black dress adorned with a red poppy, which has become a symbol of respect for those who have lost their lives in conflict.

She was accompanied by her husband William and other members of the royal family and was followed shortly afterwards by King Charles, whose wife Queen Camilla has cancelled engagements as she recovers from a chest infection.

Kate is also expected to attend the main Remembrance Day ceremony on Sunday, Buckingham Palace said on Friday.

The Princess of Wales said in September she had finished chemotherapy, but her path to full recovery would be long. At the time, the 42-year-old said she would be carrying out a handful of public engagements later in the year.

Her last public appearance was in October when she met the bereaved families of three young girls who were murdered at a dance class in northwest England.

The ceremony at the Cenotaph war memorial is held on the nearest Sunday to Nov. 11 to mark the end of World War One, and pays tribute to those who lost their lives in conflict.
