Question

Among 13,963,753 males and 14,272,325 females there were 20,734 cases of prostate cancer and 19,107 cases of female breast cancer. What is the incidence of prostate cancer per 100,000? (Hint: Only males have prostates).

Answer 1

For total population (including male and female)

`73` per
`100,000` population

For male population only

`148` per
`100,000` male population

Step-by-step explanation:

Here, out of
`13,963,753` males and
`14,272,325` females, number of people having prostate cancer is equal to
`20,734`

Total population is equal to

`13,963,753 + 14,272, 325\\= 28,236,078`

Thus, rate of fractional incidence with respect to total population is equal to

`(20,734)/(28,236,078)`

`= 0.0007340878`

Number of incidence of prostate cancer per
`100,000` people is equal to

`= 0.0007340878 * 100,000\\= 73.40\\=73`

There will be
`73` incidence per
`100,000` population

In terms of male population only it will be

`(20,734)/(13,963,753) * 100,000\\= 148`
