Breast Cancer Risk Factors Pink Ribbon

There are two types of risk factors for Breast Cancer:

Genetic Risk Factors

Gender

Breast cancer occurs nearly 100 times more often in women than in men.

Age

Two out of three women with invasive cancer are diagnosed after age 55.

Family History

If your mother, sister, father or child has been diagnosed with breast or ovarian cancer, you have a higher risk of being diagnosed with breast cancer in the future. Your risk increases if your relative was diagnosed before the age of 50.

Personal Health History

If you have been diagnosed with breast cancer in one breast, you have an increased risk of being diagnosed with breast cancer in the other breast in the future. Also, your risk increases if abnormal breast cells have been detected before (such as atypical hyperplasia, lobular carcinoma in situ (LCIS) or ductal carcinoma in situ (DCIS)).

Mensural & Reproductive History

Early menstruation (before age 12), late menopause (after 55), having your first child at an older age, or never having given birth can also increase your risk for breast cancer.

Dense Breast Tissue

Having dense breast tissue can increase your risk for breast cancer and make lumps harder to detect. Be sure to ask your physician if you have dense breasts and what the implications of having dense breasts are.


Environmental & Lifestyle Risk Factors

Lack of Physical Activity

A sedentary lifestyle with little physical activity can increase your risk for breast cancer.

Poor Diet

A diet high in saturated fat and lacking fruits and vegetables can increase your risk for breast cancer.

Being Overweight or Obese

Being overweight or obese can increase your risk for breast cancer. Your risk is increased if you have already gone through menopause.

Radiation on the Chest

Having radiation therapy to the chest before the age of 30 can increase your risk for breast cancer.

Hormone Replacement Therapy

Taking combined hormone replacement therapy, as prescribed for menopause, can increase your risk for breast cancer and increases the risk that the cancer will be detected at a more advanced stage.

Breastfeeding

Some studies suggest that breastfeeding may slightly lower breast cancer risk, especially if it is continued for 1½ to 2 years. One explanation for this possible effect may be that breastfeeding reduces a woman’s total number of lifetime menstrual cycles (similar to starting menstrual periods at a later age or going through early menopause).

Breast Cancer Lifestyle Risk Pink RIbbonSmoking

Smoking causes a number of diseases and is linked to a higher risk of breast cancer in younger, premenopausal women. Research also has shown that there may be link between very heavy second-hand smoke exposure and breast cancer risk in postmenopausal women.

Drinking Alcohol

Consumption of alcohol can increase your risk for breast cancer. The more alcohol you consume, the greater the risk.
