Intermountain Healthcare’s Dr. Kelsea Farrell reminds us about the importance of risk assessment and screenings for breast cancer.
As of December 2020, breast cancer surpassed lung cancer as the most frequently diagnosed cancer in the world, according to the World Health Organization. In the United States, the CDC has reported cancer is the second leading cause of death. Breast Cancer accounts for 33% of cancer diagnoses for women. It is the most common cancer in women, and it is the second leading cause of cancer related death behind lung cancer.
Who is affected?
Older women are most affected, with 80% of diagnoses being women over 50.
While non-Hispanic White women have the highest rate of new cases, Black women have the highest rates of death. The five-year survival of breast cancer is 91% for White women but only 82% for Black women. Addressing these disparities has been a priority of many government and healthcare leaders. One key measure has been to provide funding to low-income and underinsured women in all U.S. states, territories and tribes.
Men aren’t off the hook
Diseases such as cirrhosis and Klinefelter syndrome can increase estrogen levels, which can lead to breast cancer; other risk factors include family history and radiation exposure.
How do you know if you might have breast cancer?
The U.S. Preventive Services Task Force suggests a mammogram every 2 years for women aged 50-74; those 40-49 should discuss with their health provider when to start screening.
Screenings may consist of:
- Health Provider’s exam
- Mammogram (remember to wear no deodorant, lotion or perfume – they can skew the results)
- Ultrasound, if a closer look is needed
- MRI for an even more detailed scan
- Biopsy of tissue, if needed
Treatment options include: Surgery to remove all (mastectomy) or part (lumpectomy) of the breast, Radiation, Chemotherapy, Hormone therapy, and/or Immunotherapy.
While some breast cancer is genetic (you may have heard of the BRCA1 and BRCA2 changes), most women who develop breast cancer have no known family history of the disease. For high-risk individuals the use of hormonal blocking medication will reduce cancer development by about half.
Some lifestyle changes can help reduce your risk up to 30%: Regular exercise, maintaining a healthy weight, reducing or avoiding alcohol, avoiding smoking, breastfeeding, avoiding prolonged hormone use, limiting radiation exposure, and managing stress.
The Good News: Early detection for prevention
Overall death rates are on the decline and nearly 99% of women diagnosed with early stage cancer live 5 years or more, compared to 27% of women with late diagnoses where the cancer has spread, according to the CDC.
