Cancer survivor walked daughter down the aisle on her big day. She was given 8 months to live in 2019.

Sean Guinness, 60, from Harrogate, was treated for melanoma in 2011. He was in remission for a while but it came back eight years later. By then, it had spread to his liver and intestine, according to BBC. 

In 2019 he was given only eight months to live, but life had other plans for Guinness. He is now "cancer-free" after undergoing immunotherapy. The man then shared that he feels like the "luckiest man" on earth because he now will be able to walk his daughter down the aisle on her big day.

"When I was really ill, Amelia wanted me to write a letter that could be read out on her wedding day," he said. Even the family didn't think he would be there for her big day given how his health was at the time.

He said, "there are no words" to describe how thankful he feels. "I feel blessed that I will now be there for her."

The man said his health troubles began when he first saw a mole on his leg. It soon started bleeding, and he was eventually diagnosed with Stage 1A melanoma, and he required a small operation to remove the mole. 

Once the surgery was done, he was informed that the chances of his cancer ever coming back were "very small," so he moved on with his life. But unfortunately, in 2019, he started experiencing stomach discomfort, and scans revealed that cancer had returned, and spread a lot more. 

Three weeks after having surgery to remove a portion of his small intestine "my surgeon told me the very dramatic and scary news that I had eight months to live." He was then advised to undergo immunotherapy and was prescribed drugs like nivolumab and ipilimumab to aid his immune system in locating and eliminating the cancer cells. 

Luckily, that treatment turned out to be a success, and Guinness is now a participant in a University of Oxford study investigating the origins and management of melanoma. He had been "a wonderful advocate" for better diagnosis and patient participation, according to Mark Middleton, a melanoma oncologist at the institution. 

Now, Amelia, 28, will marry in August in the presence of her father, mother, and brother Theo, 24. "I do not think there are any words in the English language that describe the feeling of gratefulness," said Guinness.
