Kate Middleton announces she has completed chemotherapy

ALSO SPEAKING CANDIDLY BY HOW TOUGH THIS TIME HAS BEEN A LONG RECOVERY AHEAD. A MAJOR MILESTONE FOR THE PRINCESS OF WALES NINE MONTHS AFTER HER CANCER DIAGNOSIS. >> I CANNOT TELL YOU WHAT A RELIEF IT IS TO HAVE FINALLY COMPLETED BY KEY ME THERAPY TREATMENT. >> PRINCESS KATE ALSO ANNOUNCING A GRADUAL RETURN TO ROYAL DUTIES. >> I AM LOOKING FORWARD TO BOEING BACK AT WORK. >> HER VOICE NARRATING OVER INTIMATE FAMILY MOMENTS FILMED LAST MONTH IN THE ENGLISH COUNTRYSIDE WITH HUSBAND AND HEIR TO THE THROEN PRINCE WILLIAM. A RARE GLIMPSE INTO THEIR PRIVATE LIFE. >> HELLO! >> KATE ACKNOWLEDGING THE PAIN THEY HAVE FACED AS A FAMILY. >> LIFE AS YOU KNOW IT CAN CHANGE IN AN INSTANT. WE HAVE TO FIND A WAY TO NAVIGATE THE STORMY WATERS. >> AND THE UNCERTAIN JOURNEY AHEAD. >> DOING WHAT I CAN TO STAY CANCER FREE IS NOW MY FOCUS. MY PATH TO HEALING AND FULL RECOVERY IS LONG. >> THE PRINCESS MADE HER CANCER DIAGNOSIS PUBLIC IN MARCH, JUST SIX WEEKS AFTER KING CHARLES ANNOUNCED HE, TOO, WAS UNDERGOING TREATMENT FOR THE DISEASE. BOTH KEEPING THE TYPES OF CANCER AND DETAILS ABOUT THEIR PROGNOSIS PRIVATE. SINCE THEN, KATE'S BEEN SEEN ONLY A HANDFUL OF TIMES, INCLUDING AN OFFICIAL APPEARANCE AT THE TROUPING OF COLORS CEREMONY IN JUNE AND AT THE MEN'S FINAL IN WIMBLEDON IN JULY WHERE SHE WAS GREETED WITH A STANDING OCCASION. >> IT'S CLEAR THAT THIS HAS REALLY STRUCK A CORD WITH SO MANY PEOPLE, AND SHE REALLY HAS MANAGED TO SAY SOMETHING THAT RESONATES WITH PEOPLE ALL OVER THE WORLD. >> NOW KATE'S MOVING MESSAGE HELPING BOLSTER BRITAIN'S ROYAL FAMILY, WHILE GIVING HOPE TO THOSE FACING CANCER. >> I REMAIN WITH YOU, SIDE BY SIDE, HAND IN HAND. >> AND REMINDING US ALL WHAT'S MOST IMPORTANT. >> THIS TIME HAS REMINDED WILLIAM AND ME TO REFLECT AND BE GRATEFUL FOR THE SIMPLE, YET IMPORTANT THINGS IN LIFE SO MANY OF US TAKE FOR GRANTED AS SIMPLY LOVING AND BEING LOVED. >> NOW, THAT VIDEO DID LEAVE SOME QUESTIONS UNANSWERED, INCLUDING EXACTLY WHAT HER DOCTORS ARE SAYING ABOUT HER CANCER AND WHETHER SHE IS STILL UNDERGOING ANY OTHER TREATMENTS. ROYAL OFFICIALS DID NOT OFFER ANY OTHER DETAILS ABOUT HER CONDITION, CITING HER PRIVACY. BUT KENSINGTON PALACE DID SAY THE PRINCESS HAS CONTINUED TO DO A BIT OF WORK FROM HOME AND THAT SHE WILL TAKE PART IN A HANDFUL OF PUBLIC ENGAGEMENTS BETWEEN NOW AND CHRISTMAS. BUT HER MAIN FOCUS, GUYS, WILL BE MAKING A FULL RECOVERY. >> THANK YOU, KATE. LET'S BRING IN DAISY WHO IS AT BUCKINGHAM PALACE FOR US. FIRST OF ALL, CAN WE START OFF BY SAYING WHAT INCREDIBLE NEWS TO SEE THIS. THAT WAS BEAUTIFUL. SHE SAID THESE WORDS, THAT SHE'S FINISHED CHEMOTHERAPY AND IS NOW FOCUSSING ON HER RECOVERY AND STAYING CANCER FREE. WHAT DO YOU THINK THAT MEANS? >> Reporter: WELL, IT'S INTERESTING. THAT SHORT PHRASE, STAYING CANCER FREE, HAS BEEN ONE OF THE ELEMENTS OF THE FILM THAT HAS REALLY BEEN ANALYZED AND OVERANALYZED IN THE LAST FEW HOURS SINCE THAT FILM DROPPED. WE ARE TOLD BEHIND THE SCENES PLEASE DON'T ASSUME THAT THAT MEANS THE PRINCESS IS TELLING US SHE IS CANCER FREE, THAT THE CANCER IS BEHIND HER. AND, OF COURSE, ANY OF US WHO HAVE EXPERIENCED CANCER OR FAMILY MEMBERS THAT HAVE HAD IT KNOW THAT EVEN ONCE YOU ARE THROUGH THE TREATMENT, THERE IS ALWAYS THAT LITTLE VOICE IN THE BACK OF YOUR MIND SAYING, HAS IT GONE FOREVER? WILL IT RETURN? THAT'S THE MESSAGE THAT, YES, SHE'S ANSWERED THE REALLY DANGEROUS PERIOD, BUT IT'S NOT BACK TO NORMAL. OF COURSE, CHEMOTHERAPY ITSELF TAKES A LONG TIME TO RECOVER, FOR THE BODY TO RECOVER, SO THERE IS A ROAD AHEAD. >> THE FILM IS SO EXTRAORDINARY. I THINK IT'S FAIR TO SAY WE HAVE NEVER SEEN ANYTHING LIKE THIS COMING OUT OF THE ROYAL FAMILY. IT IS BEAUTIFUL AND INTIMATE. HOW IS THAT GOING OVER? AND WHAT WAS THE THINKING BEHIND THAT? >> YOU'RE SO RIGHT THAT IT WAS BEAUTIFUL AND INTIMATE. I HAVE BEEN THINKING THIS MORNING THAT IT HAS A RATHER AMERICAN FEEL TO US. IT FEELS TO US BRITS WHO ARE USED OUR ROYALS BEING A BIT MORE BUTT TOPPED UP, IT FEELS QUITE HOLLYWOOD AND VERY GLOSSY AND EMOTIONAL. AND THE CONTENT OF IT, TALKING ABOUT BEING LOVED AND LOVING YOUR FAMILY, SEEING WILLIAM AND KATE WITH THESE PUBLIC DISPLAYS OF AFFECTION, THAT'S NOT SOMETHING WE'RE USED TO. WE'RE USED TO SEEING HARRY AND MEGAN HOLD HANDS, BUT WILLIAM AND KATE HAVE BEEN MUCH MORE PRIVATE, MUCH LESS ABLE AND WILLING TO SHOW EACH OTHER THAT AFFECTION. I THINK A LOT OF PEOPLE HAVE REALLY ENJOYED AND EMBRACED THAT IDEA OF SEEING THEM SO EMOTIONAL WITH EACH OTHER. BUT IT'S TAKING A LITTLE BIT OF GETTING USED TO FOR US BRITS. >> WOW. AS AMERICANS, WE APPROVE THAT MESSAGE. WE'RE ALL ABOUT A LITTLE PDA. >> SOMETIMES WHEN YOU GO THROUGH SOMETHING SCARY AND HARD LIKE CANCER, IT JUST CHANGES, YOU KNOW, YOUR PERSPECTIVE AND HOW YOU SEE THINGS. SO SOME THINGS MAY HAVE CHANGED. >> AND PEOPLE WANT TO SEE
