Breast Cancer Causes and Risk Factors

Breast cancer develops as a result of mutated breast cells. In approximately 10% of these cases, the mutations are acquired through genetic predispositions, while most cases of breast cancer are influenced by a combination of environmental, lifestyle or hormonal risk factors. In many of these cases the exact cause of the cell mutation will never fully be known.

Risk Factors Versus Causes

The direct causes of breast cancer are not well understood as it is a very complex disease, however we do know that common risk factors often play important roles in the development of different types of cancer. Having one or more risk factors doesn’t necessarily mean you will develop breast cancer, nor does being a carrier of certain genes, however risk factors do put you at greater risk of eventually developing the disease.

Risk Factors for Breast Cancer

Some of the known risk factors that may contribute to the development of breast cancer include:

  • Inheriting certain genes such as BRCA1 and BRCA2
  • Having a close relative with breast cancer
  • Aging. While some women develop breast cancer at a young age, generally your risk increases as you get older.
  • Being female
  • Ethnicity. Research illustrates that African-American women are at a slightly higher risk of getting breast cancer than Caucasian women.
  • Being exposed to radiation
  • Being overweight or obese
  • Drinking alcohol regularly
  • Undergoing hormone therapy
  • Having already had breast cancer
  • Early menstruation or late menopause – It is thought that estrogen exposure has something to do with breast cancer development.
  • Never becoming pregnant or having children late in life
  • Smoking increases the risk of most types of cancer, including breast cancer as there are over 70 known carcinogens in cigarette smoke.

The Bottom Line

These are not the only risk factors, for example, research suggests that women with chronic nutritional deficiencies, exposure to toxins or who suffer chronic inflammation may be at greater risk for developing breast cancer as well. While certain risk factors such as age, ethnicity and genetics are unchangeable, others such as weight or lifestyle choices like drinking and smoking are modifiable. Therefor, it is important to make all the healthy lifestyle choices you can if you wish to put yourself in a lower risk category for breast cancer development.

That concludes our look at the risk factors that can help contribute to breast cancer, keep an eye out for future posts on the topic. Thanks for visiting DocChat!
