what are the causes of breast cancer?!
Question:
Answers:
I have a saying, "Genetics trumps everything". That means that you can do everything you're supposed to AND still get breast cancer. And we've all known people who ate the worst food, drank like a fish and lived to be 100.
The bottom line is that we just don't know. Diet may be a factor but if it is, we don't really know how much.
Best wishes.

Breast cancer, like other forms of cancer, is considered to be a result of damage to DNA. How this mechanism may occur comes from several known or hypothesized factors (such as exposure to ionizing radiation). Some factors lead to an increased rate of mutation (exposure to estrogens) and decreased repair (the BRCA1, BRCA2 and p53 genes). Although many epidemiological risk factors, and biological co-factors and promoters have been identified, the majority of breast cancer incidence remains unattributable, and the primary cause is unknown.
Dietary influences have been proposed and examined, but these are small effects, and do not distinguish differences in risk within populations, as well as they do between populations.
A significant environmental effect was revealed by the large difference in breast cancer incidence between countries and continents, and a migration effect which slowly increases the risk of breast cancer even across generations after migration from a country of lower incidence to a country of higher incidence, such as moving from China or Japan to the United States.
Humans are not the only mammal prone to breast cancer. Some strains of mice, namely the house mouse (Mus domesticus) are prone to breast cancer which is caused by infection with the mouse mammary tumour virus (MMTV or "Bittner virus" for its discoverer Hans Bittner), by random insertional mutagenesis. Suspicion of MMTV or other viruses in human breast cancer is controversial, and the idea is not generally accepted for lack of direct and definitive evidence. There is much more research in diagnosis and treatment of breast cancer than in its cause.

Smoking?
Mine was hereditery. I don't know if it's back or not. I even had a doctor tell me if I quit smoking, my chances are STILL as high if I did not smoke. I'm sure you're going to get different answers. There are different types of breast cancer too.
DUE TO MUTATION AND CELL PROLIFERATION IN MAMMARY GLAND SO IT IS NEED TO PREVENT THE CELL PROLIFERATION
There are things that make us more supceptible like excessive estrogen. If you are at risk due to heredity, you might want to talk to your doctor about your risk with the pill or estrogen supplements.
