The Importance of Breast Cancer Prevention
January 4, 2016
In 2015 an expected 231,840 cases of invasive breast cancer were diagnosed in women, along with 62,290 cases of non-invasive, or in-situ, breast cancer. About 1 in 8 women will develop invasive breast cancer. More than 40,000 women die yearly from breast cancer.
As a pathologist I diagnose breast cancer far too often. Even though there has been much progress in identifying risk factors for breast cancer, the majority of cases have no known risk factors or causes. As medical adviser to the Massachusetts Breast Cancer Coalition (MBCC) I understand the importance of prevention. This is finally being recognized in the medical community.
A major prevention effort by the National Institutes of Health has been launched with the goal of identifying factors that lead to the development of breast cancer. It has been found that genetic testing could improve prevention. A recent study found that genetic screening for the major breast cancer gene mutations (BRCA1 and BRCA2) but also lesser known variants, combined with known risk factors could improve the ability to identify women most at risk.
Risk factors studied include the following:
family history of breast cancer
age at menarche
number of births and age at first live birth
oral contraceptive use
combined menopausal hormone therapy use
body mass index [BMI]
history of benign breast disease
Exciting research has already identified gene variants that may predict who will benefit from breast cancer prevention drugs. Low doses of estrogen-like compounds (parabens), found in many personal care products, might increase breast cancer risk.
It doesn’t end with environmental contaminants. Diet has also been implicated in certain breast cancers. Recent research has show a link between sugar and breast cancer and risk of metastasis to the lungs. Sugar’s role in enzyme signaling pathways and the importance of inflammation in breast cancer has been uncovered.
In an effort to promote a better understanding of the importance of toxic exposures and breast cancer, the MBCC has launched the Let’s Talk Prevention: Reducing Toxic Exposures. The MBCC is helping facilitate the discussion between health professionals and patients about environmental exposures and chemicals of concern. Many chemicals of concern are industrial chemicals that do not stay isolated inside factories. Minimizing exposure to chemicals linked with negative health impacts can lessen the burden of disease and improve public health.
To make this important public health topic more palatable, MBCC has created a booklet for health professionals and a medical brochure for patients. These documents are available for download and are intended to be used in tandem.
As a health professional, the Let’s Talk Prevention: Reducing Toxic Exposures medical booklet provides providers with a wealth of resources to communicate with patients, evaluate and assess a patients’ exposure history, and further understand the effects and impact of common chemicals of concern.
For the informed patient, the Let’s Talk Prevention: Reducing Toxic Exposures brochure helps patients manage their toxic exposure risk. The medical brochure provides basic steps to reduce toxic exposures in the home and enables patients to choose safer alternatives to harmful products used daily.
The majority of breast cancer research has traditionally focused on treatment and screening while funding for prevention lags far behind. We have made great strides in our understanding of cancer at the genetic level. The precision medicine revolution has transformed how we treat cancer. While this is tremendous, far greater benefit in lives saved would be realized from efforts directed towards prevention. Additionally, the financial impact is also much greater. It is less expensive to keep a patient healthy and out of the hospital.

There is reason for optimism. Research into prevention is gaining momentum. Help keep progress moving forward. Please consider helping support MBCC in its efforts to end the breast cancer epidemic.
