Actor Tom Long has made a “miracle” recovery after being diagnosed with blood cancer and being told that he only had a few weeks left to live.

Earlier in the year, the SeaChange star took a trip to America to take part in a medical trial that could have helped boost his immune system as a last resort.

Sitting down with Lisa Wilkinson for The Sunday Project, Long looked visibly healthier in comparison to his TV appearance earlier this year and revealed that the trial treatment had acted like a “complete exorcism”.

“It was like everything was being purged out of my body, psychologically and physically,” he said.

The treatment initially forced the actor to go in and out of hospital as he fought off infections as his immune started work to restore itself.

But late last month, everything changed.

“We were having a coffee at our favourite coffee place and I got a phone call from Dr Damian Green, who was heading the trial in Seattle, and he just said that I had nothing in the bone marrow … no sign of it, zilch,” he said.

Professor Miles Prince, Long’s haematologist, revealed that the treatment was “incredibly successful” and he was now in remission.

“Is Tom cured? I don’t know. But I can tell you if you go back to the original CAR T-cell therapy patients, who had acute leukaemia, they were considered incurable and a lot of them are still alive today,” Professor Prince told The Sunday Project.

Long’s family couldn’t be happier with his recovery, with the actor’s son Ariel revealing his admiration for his father due to his incredible strength.

Tonight on Sunday @theprojecttv I have the enormous joy of catching up with much-loved actor Tom Long, star of SeaChange and The Dish, upon his return from Seattle and his last ditch attempt to find a cure for the Multiple Myeloma he has battled for seven exhausting years. In March when we last caught up, Tom was given just three months to live. His lead up to finally getting the treatment he so desperately needed, was touch and go. And just look at him and his beautiful family now! But to have this life-saving therapy, Tom had to spend hundreds of thousands of dollars and travel to the other side of the world because Australian health authorities said he, and so many others like him diagnosed with blood cancer, “don’t qualify” for local treatment. We urgently need that to change. And you can help us! You can follow Tom’s incredible journey tonight on the Sunday Project… It’s a must-watch. 😊 6.30pm @channel10au @tomlongcuretour #cartcelltherapy #multiplemyeloma #snowdomefoundation @snowdomefoundation #theprojecttv #thesundayproject

“Does it feel like it’s a miracle, what’s happened?” asked Wilkinson.

“Oh yeah,” Ariel said, with Long’s stepson Satchmo saying: “Definitely, I didn’t think it’d ever happen.”

Knowing he’s one of the lucky ones, Long aims to help other Australians gain the opportunity to take part in the trial.

The potentially life-changing treatment is currently only for two types of cancer and is publicly funded for children and young adults but can cost everyone else around $600,000.

“Oh without a doubt, it’s saved my life absolutely,” said Long. “I was a man with no hope really, not much, very limited and now I can reframe and repurpose my life and it doesn’t have to be about cancer, I can go and focus on what I want to do.”
