Jay Allen documentary to air on Channel 10

People across Macarthur are well aware of Jay Allen's long fight for melanoma awareness.

But now, people across Australia will have the chance to hear his story.

Channel 10 will air a special documentary chronicling the Tahmoor resident's mammoth 50-day Melanoma March earlier this year.

Mr Allen said he was thrilled the program - called Jay's Longest Melanoma March - was set to air this weekend.

"It means that more people learn about this horrible disease," he said.

"If one person watches the documentary and goes out and gets checked for melanoma, then that's worth it.

"There were more than 400 people on this walk with me on different stages and they had all been affected by melanoma in some way.

"This documentary shows their important work as well."

Mr Allen is a melanoma survivor and works as an ambassador for the Melanoma Institute, raising money and awareness across the country.

The former Bradbury resident was diagnosed with skin cancer as a 32-year-old in 2008, after his GP realised a mole on his ankle was actually a melanoma.

The melanoma spread from his ankle to the lymph notes in his groin, and Mr Allen has said that without medical attention at that stage, he might not be alive to tell his story today.

He said it was so important people recognised the dangers of melanoma and practised sun safe behaviour.

Mr Allen hopes the documentary will cement that message in the minds of the Australian public.

The documentarian joined Mr Allen and the other marchers during the 50-day journey from Adelaide to Sydney between March 31 and May 19 this year.

"He would have walked about 1500-kilometres himself, with the camera," Mr Allen said.

"He was definitely part of the team."

Mr Allen said members of the Melanoma March crew were gathering at a pub in The Rocks to watch the documentary together on Sunday.

"It will be a chance to celebrate our achievements," he said.

"There might also be some tears as well - it is quite an emotional documentary.

"Everyone has stories about melanoma."

Mr Allen said he found the will to get up and walk on each of the trek's 50 days because he knew he was fighting not just for future melanoma sufferers, but for the memory of all those who had been lost to the disease.

"They were my motivation every single day - I was a man on a mission," he said.

"Throughout the journey people would come up to me and give me photos of their loved ones who had passed because of melanoma.

"So I pinned their photos to my shirt or put them in my pocked.

"By the end of the march I had so many photos."

Mr Allen's march raised a whopping $606,000 for a special clinical trial into the spread of melanoma in the brain.

He said the trial had now started and he was hoping to meet the participants.

"It's really mind-blowing to see these funds go to something like this," Mr Allen said.

"It makes it all worth it."

You can watch Jay's Longest Melanoma March on Channel 10 at 1pm this Sunday, September 22.
