Prince William acknowledged Princess Kate has "a long way to go" after being asked about her latest cancer announcement.
The Prince of Wales was visiting a Swiss Valley Community Primary School, in Llanelli, Wales, a day after Kate told the world in a deeply personal video how she had completed her chemotherapy.
Multiple fans expressed their support for the princess, including one supporter, Pauline Thomas. Quoted by the Daily Mail, William told the 74-year-old: "It's good news but there is still a long way to go."
Kate had abdominal surgery in January after which she was diagnosed with cancer and began chemotherapy in late February.
Her first public appearance of the year was in June and she has still not returned to work full time, but has stopped chemotherapy.
She is not yet completely out of the words and said her main focus now is on staying "cancer free."
However, she would not be considered fully cured until she was completely free from symptoms for five years.
After meeting William, Sandra Peters, 79, was quoted in the Mail saying: "I told him, Bore da [good morning in Welsh], you have a beautiful family, I'm so pleased Kate is recovering.
"He said 'thank you very much.' He was lovely, he's so charming."
Princess Kate said in her video message: "The last nine months have been incredibly tough for us as a family. Life as you know it can change in an instant, and we have had to find a way to navigate the stormy waters and road unknown.
"The cancer journey is complex, scary and unpredictable for everyone, especially those closest to you. With humility, it also brings you face-to-face with your own vulnerabilities in a way you have never considered before and, with that, a new perspective on everything.
"This time has above all reminded [Prince] William and me to reflect and be grateful for the simple yet important things in life, which so many of us often take for granted. Of simply loving and being loved.
"Doing what I can to stay cancer-free is now my focus. Although I have finished chemotherapy, my path to healing and full recovery is long, and I must continue to take each day as it comes.
"I am, however, looking forward to being back at work and undertaking a few more public engagements in the coming months when I can."
