Five Things Women Under 40 Should Know About Breast Cancer
SEPTEMBER 30, 2019
Breast cancer is rare for women under 40. So, a breast cancer diagnosis can be shocking news for a young woman to hear.
“Breast cancer in young women can have its own risk factors and traits, and young women have their own considerations when deciding on a treatment,” says Nadine Tung, MD, head of breast medical oncology and cancer genetics at Beth Israel Deaconess Medical Center (BIDMC). “At the Young Women’s Breast Cancer Program at BIDMC, we help women navigate these difficult decisions.”
- Know Your Breasts. A lump is not the only sign of possible breast cancer. Although these don’t always indicate breast cancer, some other signs to watch for include discharge coming from the nipple or an inverted nipple. “Younger women who have breast cancer may ignore the warning signs because they believe they are too young to get breast cancer,” said Tung. “Call your doctor immediately if you find a lump or experience any other changes in your breast.”
- Know Your Family History. In younger women, breast cancer is more likely to result from genetics. If you’re 45 or younger and have been diagnosed with breast cancer, consider genetic testing to determine if you’ve inherited a cancer-causing gene, such as BRCA1 or BRCA2. Many genes that increase your breast cancer risk can be identified through a blood test.
- Know Other Risk Factors. Family history is not the only risk factor for breast cancer in younger women. Others include:
- Previous high-dose radiation to the chest
- Early onset of menstrual periods (before age 12)
- Late age pregnancy or no previous pregnancy
- Dense breasts on mammogram
- Heavy alcohol consumption
- Sedentary lifestyle
“New therapies that fight cancer using a person’s own immune system (immunotherapy) are particularly effective to treat triple-negative breast cancer, which is a type of cancer more often found in younger women,” said Tung.
“Ask questions,” encouraged Tung. “You should be an active participant in your care. Your healthcare team should explain to you any medical terms you do not understand, explain your treatment choices, possible side effects, and expected outcome.”
