Catherine, the Princess of Wales, says she has completed her treatment for cancer.

The princess spoke about her treatment in a video message in March this year.

In a new video released by Kensington Palace on Monday, she gave an update on her health, saying her focus is now "doing what she can to stay cancer free".

You can find out more about cancer and how it is treated in Newsround's special Operation Ouch.

Catherine hasn't been involved in official royal duties since January and hasn't been seen in public for a lot of the year.

In the video update, the princess says while she has finished her treatment, the "path to healing and full recovery is long".

However, Kate says she is "looking forward to being back at work and undertaking a few more public engagements in the coming months" when she can.

Her most recent appearance was in July when she was given a standing ovation at Wimbledon at the men's singles final.

This latest video message was filmed in August in Norfolk.

It shows Catherine and her family enjoying some time together in the county and having a picnic.

The Princess said she and her husband, Prince William, are "so grateful for the support" they have received.

Catherine said: "Everyone's kindness, empathy and compassion has been truly humbling."
