Kate Middleton announces she's completed chemotherapy treatment

Driving the news: "The last nine months have been incredibly tough for us as a family," she said in a voiceover to the video, which showed clips of Middleton, Prince William and their children exploring nature.

• "Doing what I can to stay cancer free is now my focus," she said, reflecting on the "complex, scary and unpredictable" journey those diagnosed with cancer embark on.
• The princess did not give a timeframe for when she will return to royal duties, but said she is "looking forward to being back at work" and "undertaking a few more public engagements in the coming months."
• She noted that while she has finished chemotherapy, her "path to healing and full recovery is long and I must continue to take each day as it comes."

Zoom out: The princess has made limited public appearances since announcing she was undergoing preventative chemotherapy, returning to the public eye for the first time in June.

• She also attended the men's final at Wimbledon in July with her daughter, Princess Charlotte, and her sister, Pippa Middleton Matthews.
• Her absence from royal duties sparked a flurry of conspiracy theories online ahead of her announcement, in which she said it had taken time to explain to her children what was happening with her treatment.

King Charles III continues to undergo cancer treatment.

• Buckingham Palace announced in February that the king had been diagnosed with cancer, but did not specify the type.
• "To all those who are continuing their own cancer journey – I remain with you, side by side, hand in hand," Kate said in the conclusion to the video shared Monday. "Out of darkness, can come light, so let that light shine bright."
