These risk factors are most significant for breast cancer is sex (gender) and age. Men can develop breast cancer, but women are 100 times more likely to develop breast cancer than in men. Breast cancer is 400 times more common in women aged 50 years compared with 20 years of age.
Family History
Another important risk factor is having one first-degree relatives (mother, brother / sister, or daughter) with breast cancer or brothers with prostate cancer. Greater risk especially if both the mother and brother / sister has had breast cancer, if the cancers in first-degree relatives one occurring in early life (before age 50), or if the cancers in relatives was found in both breast. Having a brother with breast cancer and has two brothers with breast cancer and ovarian cancer also increases a woman's risk for developing breast cancer. Families, with multiple members with other cancers may have a genetic defect leads to a risk of breast cancer is higher.

Women who have inherited the genes BRCA1, BRCA2, p53 and genes that repair damaged have an increased risk of developing breast cancer, sometimes at an early age, as has been discussed previously. But even in the absence of one of the genetic defects that affect the well known, a strong family history can indicate an increased risk due to genetic factors or environment that is specific to that particular family. For example, the increased risk in families, may be caused by exposure to environmental toxins are similar in some cases.
Breast Cancer Earlier
A woman with a history of breast cancer may develop a re-occurrence of the same breast cancer many years later if cancer cells have spread to lymph nodes (lymph nodes) or other parts of the body. A woman with previous breast cancer also have three to four times greater chance of developing another breast cancer in the opposite breast. In women who have been treated for breast cancer with breast conservation therapy [breast conservation therapy (BCT)], recurrence of breast cancer among who have been treated can also occur.

Other Breast Conditions
Although most women with breasts that fibrosistik (fibrocystic breasts) and symptoms associated with breast does not have an increased risk of developing breast cancer, texture and density of the breasts are lumpy (lumpy) can inhibit early detection of cancer with mammography. Sometimes, women with breast changes fibrosistik (fibrocystic breast) should run breast biopsies (obtain small samples of breast tissue for examination under a microscope) to ensure that a clear lumps are not cancerous.
Breast biopsies can sometimes reveal changes which abnormal cells are cancerous, but still not (called atypical hyperplasia). Women with atypical hyperplasia of the breast tissue have a four to five times enlargement of the likelihood of developing breast cancer. Some of the cellular changes that other software on the breast tissue is also associated with a small increase in risk (one-half to two times normal). This is termed hyperplasia of the breast tissue without atypia, sclerosing adenosis, fibroadenomas with complex traits, and the solitary papilloma.
Breast tumors are soft (not dangerous) commonly known as a fibroadenoma, unless he has the traits unusual under a microscope, does not bestow (give) an increased risk of cancer.
The risk of breast cancer risk may be additive. For example, women who have one first-degree relatives with breast cancer and who also had atypical hyperplasia of the breast tissue have a much higher risk for developing breast cancer than women without these risk factors.

Radiation Therapy
Women with a history of radiation therapy to the chest area as a treatment for other cancers (such as Hodgkin disease or non-Hodgkin's lymphoma) have a significantly increased risk for breast cancer, especially if the treatment of radiation received by the time a young age.

Factors Hormones
The women who started coming month periods before age 12 years, those who have a late menopause (after age 55), and those who have a first pregnancy after age 30, or those who never had children have an increased risk developing breast cancer is lightweight (less than twice the normal risk). The early onset of menses, late arrival of menopause, pregnancies and late or absent, all are factors that increase a woman's level of lifetime exposure to estrogen.
Studies have confirmed that long-term use (several years or more) of hormone therapy after menopause, especially estrogens and progesterone combined, lead to an increased risk of developing breast cancer. This risk seems back to normal if a woman was not taking hormone therapy for five years or more. Similarly, some studies show the birth control pills cause an increased risk of breast cancer is small, but this risk was also returned to normal after 10 years of not using it. The decision whether to use hormone therapy or birth control pills involve consideration of the risks against the benefits and should be distinguished from other individuals (individualized) after consulting a doctor.
Lifestyle Factors
Dietary factors (food) such as foods high in fat and alcohol consumption have been implicated as factors that increase the risk of breast cancer. Smoking, drinking coffee, the use of antiperspirants, and stress does not appear to increase breast cancer risk. It is important to remember that 75% of women who develop breast cancer have no risk factors other than age. Thus, screening and early detection is essential to every woman regardless of the presence of risk factors.
