The role of young population structure in determining age distribution of breast cancer in Jordan

Abstract EN

Previous reports noted a high proportion of young Jordanian breast cancer (BC) patients.

This study was 3erformed to find whether this is reproducible and to examine the role, if any, of a young population struc-;ure in causing this.

We hypothesized that the age distribution (AD) of BC in Jordan is independent from the 3opulation structure.

By finding that the AD of BC in a model population, where the population structure of Fordan is similar to the USA, was significantly different (P = 0.01) from the observed AD in Jordan, we rejected this hypothesis.

We conclude that a young population structure, as well as a low incidence in older patients, are the main •easons behind a high proportion of young patients with BC in Jordan.

This may also be valid in other coun-xies having an early onset/low incidence rate of BC.
