Being Female
Being born female is the main risk factor for breast cancer.
Although men can get breast cancer, it’s about 100 times more common in women [35]. Men don’t have the same complex breast growth and development as women.
In 2017 (most recent data available) [35]:
| Women | Men | |
|---|---|---|
| Incidence (new cases) | 131.6 per 100,000 | 1.3 per 100,000 |
