Breast Cancer Awareness Month

What is breast cancer?

Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. The damaged cells can invade surrounding tissue, but with early detection and treatment, most people continue a normal life.

Facts about Breast Cancer in the United States

  • One in eight women will be diagnosed with breast cancer in their lifetime.
  • Breast cancer is the most commonly diagnosed cancer in women.
  • Breast cancer is the second leading cause of death among women.
  • Each year it is estimated that over 220,000 women in the United States will be diagnosed with breast cancer and more than 40,000 will die.
  • Although breast cancer in men is rare, an estimated 2,150 men will be diagnosed with breast cancer and approximately 410 will die each year.

 

Causes of Breast Cancer: How did this happen?

When you’re told that you have breast cancer, it’s natural to wonder what may have caused the disease. But no one knows the exact causes of breast cancer. Doctors seldom know why one woman develops breast cancer and another doesn’t, and most women who have breast cancer will never be able to pinpoint an exact cause.  What we do know is that breast cancer is always caused by damage to a cell’s DNA.

What Do Scientists Actually Know About The Cause Of breast cancer?

Cancer grows when a cell’s DNA is damaged, but why or how that DNA becomes damaged is still unknown. It could be genetic or environmental, or in most cases, a combination of the two. But most patients will never know exactly what caused their cancer. However, there are certain established risk factors that are associated with breast cancer.

Environmental and 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 to the Chest:  Having radiation therapy to the chest before the age of 30 can increase your risk for breast cancer.
  • Combined Hormone Replacement Therapy (HRT):  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.

 

Good News About Breast Cancer Trends

In recent years, perhaps coinciding with the decline in prescriptive hormone replacement therapy after menopause, we have seen a gradual reduction in female breast cancer incidence rates among women aged 50 and older. Death rates from breast cancer have been declining since about 1990, in part to better due to screening and early detection, increased awareness, and continually improving treatment options.
