Why the United States and Western Europe have breast cancer incidence higher? More than one million women are diagnosed with breast cancer each year, and rates of breast cancer incidence varies considerably, with, it is true, the highest rate in the west, with the United States with the The highest rates of all and the rates are lowest in Africa and Asia
The scheme easy, pat answer would be.
However, a more realistic explanation I think it would be screening and life expectancy.
Improved and more extensively screening for breast cancer means a lot more cases will be diagnosed in a country that has no such extended screening program.
And 80% of breast cancers occur in women over 50 years, the average age at diagnosis is a little over 60.
Thus, the countries of better health care, ironically, have a greater number of people developing cancer associated with age (because many more people live in 50) that the will of a country that has an expected living much lower.
And of course there are things we can not explain. Japan has a much lower incidence of breast cancer than the U.S. or Western European countries, and this is often seized by people wishing to claim the Western diet is to blame for breast cancer. But the incidence of Japanese stomach cancer far exceeds that of Western countries.

Really? Are you sure? Is it not at least as likely that the United States and Western Europe have the most advanced capabilities disgnostic, and therefore properly diagnose a much higher percentage of breast cancer cases that occur? (It is, in fact, is what happens *)
If you have breast cancer in Togo or Mongolia or Swaziland or Tannu Tuva, it spreads until it kills you, and your death is recorded as having been the result of "bad spirits" .. .
There are several possible answers to your question.
1) The United States and Western Europe may have better overall health care, so that more women are diagnosed and treated in other countries where women may not have adequate access to medical services.
2) The Western diet and obesity (especially U.S.) to contribute to a higher rate of breast cancer since obesity is a risk factor for breast cancer.
3) Genetics - some genetic mutations are performed in populations of Western Europe and America than in some women more at risk.
4) Then there is the theory bra (not yet proven) that bra is decreasing the flow of lymphatic fluid from the breast tissue and underarm, which increases the risk of breast cancer. The incidence of breast cancer is lower in countries where women traditionally do not wear bras.
