A 18-year-old female asked:

what are some causes of breast cancer?

Unknown: There are some increased breast cancer risks associated with obesity, hormone medication use, early age at first menstruation, late age at first childbirth, etc. Only about 15% of breast cancers occur because of genetic inheritance. See this site with more information: http://media.Komen.Org/breastcancer101tool/english/video-player.Html#kbc_01_01.

Several: Family history, obesity, estrogen, being female, alcohol intake, decreased physical activity, and bad luck.
Dr. Barry Rosen

Environment/Heredity: Unfortunately, we don't know enough about breast cancer to be able to identify the specific causes; at best, we know of some conditions that are associated with breast cancer, such as high and/or prolonged unopposed estrogen levels (early menarche, late menopause, hormone replacement). App. 10-15% of cases are due to hereditary risks, the rest are environmental.
Dr. Travis Kidner

Many: The number one risk factor is being female. Other risk factors are family history, early menarche, late menopause, genetic predisposition, unopposed estrogen therapy, history of radiation to the chest wall, and a personal history of breast cancer.

1 in 8 women: Unfortunately, 1 in 8 women will develop breast cancer over the course of their lives. If you have no family history and you eat healthy and go for routine screening mammograms and perform self exams, you should be able to catch anything abnormal and treat it early.

I wish we knew!: We really don't know what causes breast cancer. We do know that women with a long exposure to estrogen are at a higher risk. If you started your period early, or never got pregnant, you have more estrogen exposure. But these are things you can't really change. However, alcohol intake is associated with breast cancer, so decrease how much you drink. And lower your body fat. And avoid bpa plastics.

Difficult question: Tough to answer in 400 characters, but cancer develops when changes in the genes (dna) of a cell cause that cell to divide out of control. Those dna changes can be genetic (inherited) or environmental (triggered). We know some things that cause cancer (smoking for lung, uv radiation for skin) but many remain unknown, particularly for breast.
Dr. Ed Friedlander
Pathology 44 years experience
Mostly dumb luck: There are a couple of genes that predispose; truly high-dose radiation is a known risk. If a woman spends most of her reproductive life pregnant or lactating, she's protected, but this is not for everyone. Some hormonal preparations raise risk. I'm skeptical about diet, alcohol and smoking -- it's uncertain -- and I do not believe the "conservative" claim that it's linked to abortion.
Dr. Sewa Legha

Mostly unknown: Breast cancer is common and often runs in families(it is genetic). But most often it can come on out of no where...So the cause is unknown in 90% of the cases. Female hormones(estrogens have a lot to do with its causation.. Eat healthy(low fat diet), exercise and keep your weight normal, do not smoke or drink alcohol. These are some precauations to reduce your risk. Also get an annual mammogram.

Surgical Oncology 64 years experience
No: There are two causes of breast cancer. Those cases developing due to hereditary factors which represent about 5%of patients and those that are acquired. The major acquired cases are produced secondary to a virus, the mmtv virus that enters the epithelium of the duct attaching to the wnt-1 gene to produce a stimulating factor called b catenin which forces the cell to transform to malignancy.
