Sarah Ferguson will attend alongside Princess Beatrice and Princess Eugenie to support a cause near to their hearts.
The mother-daughter trio will attend an event to encourage cancer awareness among young people, after the Duchess of York's interview with The Times in which she revealed her double cancer diagnosis.
Sarah, who is a patron of the Teenage Cancer Trust, also sent a message endorsing the #AndYoungPeople initiative.
The Duchess feels that teens and young adults with cancer are regularly overlooked by those formulating health plans and policies. The consequences can be disastrous.
Prince Andrew's wife has pushed UK authorities to include youngsters in the national cancer plan. She emphasized "amplifying the voices of teens with cancer."
According to sources, Sarah, along with Beatrice and Eugenie, who are also raising awareness about the fatal disease cancer, will visit a cancer unit funded by the Teenage Cancer Trust today.
Notably, the Yorks were last seen attending the Easter service among senior members of the royal family.
