Incidence rate: Women 125 per 100,000 Men 1.2 per 100,000
This statistic says that for every 100,000 women in the U.S., 125 developed breast cancer. For every 100,000 men, fewer than two developed breast cancer.
From these numbers, we can see that breast cancer is about 100 times more common in women than in men
(125 ÷ 1.2 = 104, or about 100).

you want the ratio r, of cancer in women to cancer in men.
r = 125/100000 : 1.2/100000 = 125:1.2 = 104:1
