Debunking Common Breast Cancer Myths: Expert Insights
Did you know that one in eight women in the U.S. will be diagnosed with breast cancer in her lifetime? Despite its prevalence, there are still several misconceptions surrounding this disease. Dr. Megan Kalambo, an associate professor at the Department of Breast Imaging at The University of Texas MD Anderson Cancer Center, shares her insights on some of the main myths she has encountered among women.
Myth #1 – A Lump Always Indicates Breast Cancer
Although a breast lump is the most common symptom of breast cancer, its absence does not rule out the presence of the disease, warns Dr. Kalambo. She emphasizes the importance of annual screening mammograms, which can detect early-stage breast cancer before any symptoms appear. In fact, many women diagnosed with breast cancer have no signs or symptoms at all.
Other Warning Signs to Watch Out For
In addition to breast lumps, Dr. Kalambo highlights other potential signs and symptoms that should prompt further evaluation:
- Swelling in or around the breast, armpit, or collarbone
- Skin changes like thickening, redness, scaling, itching, or swelling (with or without a lump)
- Nipple changes or discharge
- Breast pain lasting for more than four to six weeks (less common symptom)
Myth #2 – Monthly Self-Exams Are Essential
Contrary to popular belief, monthly breast self-exams do not provide clear benefits in detecting breast cancer, especially when combined with annual screening mammograms, according to research studies. The American Cancer Society no longer recommends clinical breast exams or self-exams as effective screening methods. Instead, Dr. Kalambo advises women to be familiar with the normal look and feel of their breasts. Any changes should be promptly reported to a doctor, as this is just as effective as a formal self-exam.
Myth #3 – Bras and Antiperspirants Cause Breast Cancer
Dr. Kalambo dispels the notion that wearing or not wearing a bra, or using antiperspirants or deodorants, has any scientific connection to the development of breast cancer. Extensive research has found no evidence to support these claims.
Myth #4 – Lifestyle Choices Do Not Affect Breast Cancer Risk
While family history does influence breast cancer risk, lifestyle factors also play a significant role. These modifiable risk factors include personal behaviors such as diet and physical activity. Maintaining a healthy weight is one of the most effective ways to reduce breast cancer risk, emphasizes Dr. Kalambo. Being overweight or obese, especially after menopause, increases the risk. She recommends a plant-based diet rich in fruits, vegetables, whole grains, and beans, along with smoking cessation, limited alcohol intake, and at least 30 minutes of daily physical activity.
Myth #5 – Breast Cancer Only Affects Older Women
Contrary to popular belief, breast cancer can also affect men. While the disease is more common among women, about one in every 100 breast cancers diagnosed in the United States is found in a man, according to Dr. Kalambo. Men with a family history of breast cancer or specific genetic mutations also face an increased risk.
