The Princess of Wales said in March that she was undergoing treatment for cancer in an emotional statement.
In her most recent post, shared on 14 June, the 42-year-old explained: "I have been blown away by all the kind messages of support and encouragement over the last couple of months.
"It really has made the world of difference to William and me and has helped us both through some of the harder times.

"I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days. On those bad days you feel weak, tired and you have to give in to your body resting.
"But on the good days, when you feel stronger, you want to make the most of feeling well. My treatment is ongoing and will be for a few more months.
"On the days I feel well enough, it is a joy to engage with school life, spend personal time on the things that give me energy and positivity, as well as starting to do a little work from home."
The Princess continued: "I’m looking forward to attending The King’s Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet.

"I am learning how to be patient, especially with uncertainty. Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal.
"Thank you so much for your continued understanding, and to all of you who have so bravely shared your stories with me."
Following Kate's update, the family appeared together at Trooping the Colour this weekend.
The children later shared a sweet image on Father's Day (16 June), paying tribute to their dad, Prince William.
Alongside a photo of Prince William and the children standing on the sand dunes, looking out towards the ocean, the kids wrote: "We love you, Papa. Happy Father’s Day."
