Kate Middleton's role in the royal family continues to expand. 

In fact, King Charles III honored the Princess of Wales with a new title in an April 23 announcement. 

Kate—who shared her cancer diagnosis in March—has been appointed as "Royal Companion of The Order of the Companions of Honour." Her Royal Highness' epithet is brand new, as no one has held the title before her. However, King George V founded the Order of the Companions in 1917 to recognize achievements in public service, arts, medicine and sciences. 

And while Kate is currently laying low amid her health journey, the title comes as no surprise given her dedication to organizations like Little Princess Trust and her own childhood development initiative, Shaping Us. The 42-year-old has also emphasized that she plans to return to her royal duties as soon as possible.

"My work has always brought me a deep sense of joy," Kate said in a March 22 social media video. "I look forward to being back when I'm able, but for now I must focus on making a full recovery."

But Kate isn't the only one who was bestowed a new title.

Queen Camilla received the title "Grand Master and First or Principal Dame Grand Cross of the Most Excellent Order of the British Empire." And Prince William—who shares children Prince George, 10, Prince Charlotte, 8, and Prince Louis, 6 with Kate—received a new title of "Great Master of the Most Honourable Order of the Bath," which was previously held by King Charles. 

The Prince of Wales has continued to proceed with his own royal duties after his wife's health update, as well as stepping up in place for his father (who announced his own cancer diagnosis on Feb. 5) on several occasions—and Kate has expressed gratitude for his support. 

"Having William by my side is a great source of comfort and reassurance," Kate added in her March 22 video. "I am well, and getting stronger every day by focusing on the things that will help me heal in my mind, body and spirits."

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."

After keeping up her full slate of engagements in the wake of her husband's cancer diagnosis, the palace cleared Camilla's schedule.

"Throughout this period, His Majesty will continue to undertake State business and official paperwork as usual.The King is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure. He remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible."

Shortly after Kate's hospitalization was made public, Buckingham Palace shared that Charles "has sought treatment for an enlarged prostate."
