The princess is currently undergoing preventative chemotherapy and in her latest message, she said the treatment is ongoing and will be for the next few months.

Her mother is said to have been a pillar of strength to her daughter, rallying around her family and helping her through her treatment.

Kate’s parents were last seen in public back in December when they attended her annual Carol Service during Christmas time at Westminster Abbey.

Just three months later, Kate would appear on video and shock the world by announcing she had been diagnosed with cancer.

In her latest update, published last Friday, the future Queen said that she has “good days and bad days” while she continues to undergo preventative chemotherapy, explaining that during the latter she is left “weak and tired”.

But when she is well enough she said she can focus on the things that give her joy, most notably her family and her work.
