The Dose 24:16 What should people who’ve never smoked know about lung cancer?

Toronto resident Winhan Wong's lung cancer journey began in 2016, with a nagging cough that just wouldn't go away.

A visit to his family doctor and a series of scans revealed the culprit: two litres of fluid in Wong's right lung and a three-centimetre tumour.

Though his doctors assumed otherwise based on the test results, Wong had never once smoked a cigarette in his life.

“I was told that it was Stage 4,” Wong told White Coat, Black Art host Dr. Brian Goldman.

“There's one doctor that said I might have six months, and then my oncologist said I had basically one to 10 years.”
