A 9-year-old cancer patient has defied all odds by being declared completely cancer-free after undergoing pioneering, yet incredibly dangerous surgery.

Scroll on to read this incredible tale...

Out of all the illnesses in the world, cancer is by far one of the most devastating.

A result of the uncontrolled growth of abnormal cells in the body, cancer develops when the body's normal control mechanism stops working.

Instead of old cells dying like they're supposed to...

They instead mutate, forming new, abnormal cells.

Cancer can occur anywhere in the body.

But breast cancer, prostate cancer, and lung cancer are by far the most common.

And the treatment is grueling.

The goal of treatment is to kill as many cancerous cells as possible, all the while avoiding any damage to the normal and healthy cells nearby.

However, this isn't always possible.

The most common treatment, chemotherapy, acts as a "poison" and kills off the abnormal cells. However, it can often kill normal cells, too, which makes people incredibly ill, resulting in hair loss, weight loss, and general sickness.

Though chemotherapy has been proven to have positive effects on eliminating cancerous cells from the body...

It isn't a cure... And we are yet to discover one.

We are a long way off from finding an official cure for cancer...

And the numbers of those being diagnosed with the illness keep on rising every year. In 2019, an estimated 1.8 million cases of cancer were diagnosed in the United States alone.

And, out of those diagnosed with the devastating illness...

An estimated 606,880 sadly passed away.

These numbers are simply devastating.

Medical researchers have been working hard for decades to find a cure for the illness and, though they haven't found one officially, they have come up with many alternative methods to combat the disease.

More and more pioneering surgeries are now available for cancer patients...

Where cancerous tumors can be successfully removed.

And now, news has emerged of a completely new type of surgery being conducted for the first time...

And it has successfully rid the patient's body of any traces of cancer. Here, we have the remarkable story of 9-year-old Saul Hayden, from Cheshire, U.K, who, after being suddenly diagnosed with a rare form of cancer, bravely underwent the pioneering treatment.

Saul was a seemingly healthy little boy.

But, after suddenly feeling unwell with stomach pains and losing his appetite in April last year, he was taken to the doctors to undergo various tests.

The test results were devastating.

After being referred to Alder Hey Children's Hospital in Liverpool, the youngster was diagnosed with stage four malignant rhabdoid tumor of the liver, one of the rarest and most aggressive forms of cancer there is.

The survival rate for this type of cancer is slim.

And doctors warned Saul's mom, Vicki, that just fifty-three other people in the world had fought the disease - with only 5 having ever survived.

Saul underwent ten rounds of brutal chemotherapy...

Before he was then offered pioneering surgery which would remove his liver, remove the cancer, then put it back in.

The surgery carried with it many risks.

"Without the surgery, there was no chance for him," Vicki explained, "The operation was so rare they were reluctant to do it at all."

And not many had survived this type of surgery in the past.

"They were worried he wouldn't make it at all. I was told one in ten adults don't survive this type of operation so it was even riskier for him. I can't put into words what it has been like for us." Vicki said.

But they decided to take the risk.

On September 18th at Birmingham Children's Hospital, surgeons isolated the blood flow to Saul's liver, physically removed the organ, cut out the cancerous cells, then placed it back into his body.

Remarkably, Saul survived the dangerous operation.

"I don't know how but he has found the strength from somewhere to keep smiling through everything." Vicki explained, "They have said they are amazed at how well he has done. We were warned that him not surviving was more likely than survival."

And, after a scan in January this year...

Saul was officially declared as cancer-free! The youngster still attends regular check-ups, but it is hoped that he will be able to return to school by the end of the year. Congratulations, Saul!
