Kate Middleton is receiving treatment for cancer, Kensington Palace announced in March. The Princess of Wales's diagnosis comes following major abdominal surgery in January.

Kensington Palace did not specify when Kate learned she had cancer, only saying she was. made aware of the diagnosis "once post-operative tests had been completed and results reviewed." Here, a full timeline of the Princess of Wales's cancer diagnosis and treatment:

January 16: Kate undergoes planned abdominal surgery.

Kensington Palace publicly shared the news of her surgery a day later. "Her Royal Highness The Princess of Wales was admitted to The London Clinic yesterday for planned abdominal surgery," Kensington Palace said in a statement. "The surgery was successful and it is expected that she will remain in hospital for ten to fourteen days, before returning home to continue her recovery. Based on the current medical advice, she is unlikely to return to public duties until after Easter."

They added, "The Princess of Wales appreciates the interest this statement will generate. She hopes that the public will understand her desire to maintain as much normality for her children as possible; and her wish that her personal medical information remains private." At the time, it was understood her surgery was not cancerous.

January 29: Kate is discharged from the London Clinic.

After thirteen days in the hospital, Kate was discharged. (Coincidentally, on the same day King Charles was discharged from the same hospital.)

"The Princess of Wales has returned home to Windsor to continue her recovery from surgery. She is making good progress," Kensington Palace said in a statement. "The Prince and Princess wish to say a huge thank you to the entire team at The London Clinic, especially the dedicated nursing staff, for the care they have provided. The Wales family continues to be grateful for the well wishes they have received from around the world."

She began recuperating at home at Adelaide Cottage in Windsor.

Sometime in February: Kate begins chemotherapy treatment.

Following her surgery, post-operative tests found cancer, and at some point in late February, Kate began "a course of preventative chemotherapy," according to a Palace spokesperson.

"The surgery was successful," Kate later shared in a video message. "However, 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. This of course came as a huge shock, and William and I have been doing everything we can to process and manage this privately for the sake of our young family."

March 22: Kensington Palace announces Kate has cancer, and releases personal message from the Princess.

News of Kate's cancer diagnosis was made public in March, along with a video message from the Princess (watch above). The Palace said they will not be sharing what type of cancer Kate has. "The Princess has a right to medical privacy, as we all do," a Palace spokesperson said.

The Palace has not shared a specific timeline regarding Kate's recovery, end to her chemotherapy treatment, or when she could return to her public duties. In her message, Kate said, "My work has always brought me a deep sense of joy and I look forward to being back when I am able, but for now I must focus on making a full recovery."

A day after Kate's diagnosis was made public, Will and Kate thanked the public for their well wishes. A Kensington Palace spokesperson said in a statement, "The Prince and Princess are both enormously touched by the kind messages from people here in the UK, across the Commonwealth and around the world in response to Her Royal Highness' message. They are extremely moved by the public's warmth and support and are grateful for the understanding of their request for privacy at this time."

April 29: Kate and William celebrate their wedding anniversary.

Kensington Palace shared a never-before-seen picture of the couple from their wedding day, taken by photographer Millie Pilkington (who just photographed King Charles and Queen Camilla for their 19th wedding anniversary). "So excited and honored that they should wish to share it," Pilkington wrote on Instagram.
