The world of cancer research is changing quickly but most scientists agree that the cause of breast cancer is multifactorial. Breast cancer develops as a result of a combination of modifiable and non-modifiable risk factors.
Non-Modifiable Risk Factors for Breast Cancer
Non-modifiable risk factors include things that are mostly out of your control to change, depending on where you are in your life. They include:
Gender
Females are 100X more likely to develop breast cancer than males, however, men can develop breast cancer, too.
Age of Menarche
The age at which a woman begins her period may make a difference. The lower the age, the slight increase in your risk for potentially developing breast cancer.
Parity
Having children lowers risk.
Age of First Pregnancy
The lower the age of your first pregnancy, the lower the risk. Breastfeeding also lowers risk.
Current Age
Older age increases risk.
Age at Menopause
Going through menopause later age increases risk.
Mammographic Density
Increased breast tissue density increases risk (this is now required on mammogram reports).
Breast Biopsies
The more breast biopsies you have as well as a certain pathology on the biopsy report, may increase risk.
Ancestry
Ashkenazi Jewish/Eastern European Jewish heritage increases risk.
Family History
Incidence of breast and/or ovarian and some other cancers (pancreatic, colon, prostate) in first and second degree relatives (children, siblings, parents, grandparents, aunts and uncles), especially occurring in successive generations, increases risk.
It is important to know your family medical history so you can undergo risk assessment and possibly qualify for more aggressive screening protocols.
Genetic Mutations
Certain known genetic mutations in family members can increase risk.
Modifiable Risk Factors for Breast Cancer
Modifiable risk factors include things that you can actively work on to decrease your risk. These include:
Smoking
Tobacco is a promotor for many cancers, including breast cancer. Quitting is the single best thing you can do for your health.
Alcohol
More than three alcoholic drinks per week may increase your risk for breast cancer.
Healthy Diet
A healthy diet that consists of: low sugar, low fat, low processed food, low preservatives/chemicals, less red meat, more fish, more fresh fruit and vegetables, may decrease the risk of many cancers. An example is the Mediterranean Diet.
Body Mass Index (BMI)
Maintaining a healthy weight decreases risk. A healthy goal for your BMI is 25.
Exercise
A minimum of three hours of moderate exercise per week, even without weight loss, decreases risk.
Medications/Hormones
Limiting oral contraceptive pills (OCPs) to 10 years, total, and using the least hormone replacement therapy (HRT) at menopause decreases risk. Fertility treatment does not increase risk.
Environmental Exposure(s)
Limit toxins and radiation exposure in the home and work.
- Utilize personal protection equipment (PPE).
- Have well water tested. Wash produce and consider buying “organic”.
- Examine beauty products including permanent hair dye, cosmetics, etc.
Stress Reduction
Investigate and develop a regular program with meditation, yoga, and/or exercise. Seek out counseling and/or support groups, if needed.
Monthly Self Breast Exams
Self breast exams are best done at the end of menses, or the first of the month, if no menses. If a new mass doesn’t go away after 1 cycle or 1 month, schedule an appointment for evaluation. Many women find their tumors between scheduled screenings.
Annual Clinical Exams and 3D Mammograms
Annual clinical exams and/or 3D mammograms should be started for all women starting at 40 years of age (earlier, if high risk) without upper limit, if you are relatively healthy and able to undergo treatment.
It is much better to find and address a tumor when it is small, regardless of age. If mammograms are painful, schedule for the week after your period, and pre-medicate with over-the-counter Ibuprofen or Tylenol.
Maintain Appropriate Screenings
Continue annual checkups or well-woman exams, have vitamin D levels checked annually, and supplement, if indicated. Stay current on other cancer screening protocols – PAP and pelvic exams, skin checks and colonoscopies, as appropriate.
