反例太多了，一位金牌选手41岁就因癌症去世

Dual Commonwealth Games marathon gold medallist Kerryn McCann has died from cancer.

McCann was first diagnosed with breast cancer in August last year while she was pregnant with her third child.

She finished a course of chemotherapy in January this year but was then diagnosed with a secondary cancer in her liver.

McCann passed away at her home near Wollongong on the New South Wales south coast overnight, surrounded by her family.

She was 41.
