Kate Middleton Shares She's Completed Chemotherapy Treatment After Cancer Diagnosis

Kate Middleton is sharing a major update in her health journey.

Nearly six months after sharing she has been diagnosed with cancer, the Princess of Wales has announced she's completed her chemotherapy treatment.

"As the summer comes to an end, I cannot tell you what a relief it is to have finally completed my chemotherapy treatment," Kate—who shares kids Prince George, 11, Princess Charlotte, 9, and Prince Louis, 6, with husband Prince William—said in a Sept. 9 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."

She continued, "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."

In her message, Kate, 42, also noted that her health journey has given her and William, also 42, the opportunity to reflect. "And be grateful for the simple yet important things in life,” Kate added, “which so many of us often take for granted."

"Doing what I can to stay cancer free is now my focus," she continued. "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."

As Kate noted, "despite all that has gone before," she's looking forward to entering "this new phase of recovery with a renewed sense of hope and appreciation of life."

"William and I are so grateful for the support we have received and have drawn great strength from all those who are helping us at this time," she concluded her note. "Everyone’s kindness, empathy and compassion has been truly humbling. To all those who are continuing their own cancer journey – I remain with you, side by side, hand in hand. Out of darkness, can come light, so let that light shine bright."

Earlier this year, Kate opened up about her health journey, sharing that though it was an "incredibly tough couple of months for our entire family," she was grateful to have a "fantastic medical team" who have taken care of her.

"As you can imagine, this has taken time," she shared in a March 22 video, which came just weeks after King Charles III also opened up about his diagnosis. "It has taken me time to recover from major surgery in order to start my treatment. But, most importantly, it has taken us time to explain everything to George, Charlotte and Louis in a way that is appropriate for them, and to reassure them that I am going to be ok." 

Kate, who did not disclose further details about her diagnosis, went on to note how much the outpouring of support has meant to her during such a difficult time.

"Having William by my side is a great source of comfort and reassurance too," she added at the time. "As is the love, support and kindness that has been shown by so many of you. It means so much to us both."

Nearly three months after sharing her cancer diagnosis, the Princess of Wales said that she's "making good progress" with chemotherapy, though there are "good days and bad days" amid her health journey.

"On those bad days you feel weak, tired and you have to give in to your body resting," Kate wrote on Instagram June 14. "But on the good days, when you feel stronger, you want to make the most of feeling well."

She added, "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."

In a March 22 video message, the Princess of Wales shared that she'd been diagnosed with cancer after undergoing abdominal surgery in January.

"It was thought that my condition was non-cancerous. The surgery was successful," she said before noting that tests after the operation found cancer had been present. "My medical team therefore advised that I should undergo a course of preventative chemotherapy and I am now in the early stages of that treatment."

After photo agencies pulled the picture Kensington Palace shared of Kate since having her abdominal surgery on March 10, the Princess of Wales addressed claims the photo was doctored. 

"Like many amateur photographers, I do occasionally experiment with editing," she tweeted on March 11. "I wanted to express my apologies for any confusion the family photograph we shared yesterday caused. I hope everyone celebrating had a very happy Mother's Day. C."
