A CANCER survivor says he would be dead if he hadn t been diagnosed a few days before lockdown after two chances were missed. Greenock man Mark Humphreys, 47, had been to his GP three times with a sore throat and was given antibiotics and sprays before a practice nurse at Regent Medical Practice finally raised the alarm. Within an hour he found out he had throat cancer. Mark, of Wellington Street, had been off work after breaking his hand and his wife persuaded him to go back to the doctor for a final time on March 12 last year. Mark says this saved his life.
