Now 42, Alex was initially diagnosed with melanoma in 2012.
He was treated with surgery, but three years later the disease had spread to his lymph nodes.
Alex underwent several operations to remove the tumours, followed by a course of post-surgery radiotherapy, and then later, immunotherapy.
“I finished radiotherapy and my scans were clear, however under two years later my cancer returned,” he said.
“I was offered immunotherapy and it completely saved my life.
“Without it I was expected to have died in 2019, leaving behind my wife and two children, then aged four and seven.
“It was a life-changing treatment for me and I’m now in my eighth year of complete remission and able to lead a normal and active life.”
But Alex, a lawyer who lives in Surrey, warns the treatment is not straightforward.
“Whilst the treatment’s results have been amazing, it did come with some tough challenges,” he said.
“I suffered from some pretty significant side effects, which resulted in me being hospitalised for two weeks.
“I’m very clear on the importance of researching and understanding immunotherapy side effects to make the treatment as effective and as kind as possible.”
