A man has said his life was saved by a shark attack when it revealed he had a cancerous tumour.
Mr Finney said: “That night I started having pretty serious chest and back pains.”
And it continued to get worse on his return home to Fitchburg, Massachusetts.
A visit to hospital confirmed the pain was caused by internal bruising caused by the attack.
However, the medical staff who examined him also found he had a cancer.
“They had discovered a growth, or a tumour, on my right kidney about the size of a walnut,” Mr Finney said.
After undergoing surgery to remove it, he said: “If this didn’t happen with the shark, causing me to go in with this chest pain, I would have never known about this cancer.”
The surgeon who operated on him, Dr Ingolf Tuerk, of St Elizabeth’s Medical Center, Brighton, said: “It led to a situation that saved his life.
“That’s pretty fascinating when you think about it.”
