I had a large disagreement with a female coworker who made a similar quip about prostate cancer 'not being a thing'. We went to her PC, I googled prostate vs breast cancer percentages and there were at least five of us standing there. Then she said - The stats are wrong on that website because everyone knows breast cancer is a more serious problem. My supervisor at the time let out a loud OKAAAAAY let's all leave the area now.
