Breast Cancer Awareness Month is a reminder to pay attention to breast health, but prevention and early detection matter year-round. Breast cancer can affect people in different ways, and early breast cancer often does not cause noticeable symptoms. That is why understanding your risk factors, knowing what changes to watch for, and talking with your doctor about screening are important parts of proactive care.
In the U.S., about 1 in 8 women will be diagnosed with breast cancer during her lifetime. While not every case can be prevented, there are steps you can take to better understand your personal risk, support your overall health, and know when to seek medical guidance.
At CLS Health, our primary care providers, OB/GYNs, imaging partners, oncologists, and plastic surgeons work together to support patients through breast health concerns, screening conversations, diagnosis, treatment, and survivorship when needed.
Key Takeaways
Breast cancer awareness is important year-round, not only during October.
Some breast cancer risk factors cannot be changed, such as age, family history, genetics, and dense breast tissue.
Healthy lifestyle habits may help lower risk, including regular exercise, maintaining a healthy weight, limiting alcohol, and avoiding smoking.
Early breast cancer may not cause symptoms, which is why screening and regular conversations with your doctor are important.
Talk with your healthcare provider if you notice a breast lump, nipple changes, skin changes, discharge, or other new breast changes.
What Is Breast Cancer?
Breast cancer begins when abnormal cells in the breast grow out of control. These cells may form a tumor, which can be benign, meaning non-cancerous, or malignant, meaning cancerous. Breast cancer can develop in different areas of the breast and may vary in type, stage, and treatment approach.
The exact cause of breast cancer is not always known. In many cases, a combination of genetic, hormonal, lifestyle, environmental, and age-related factors may influence a person’s risk. Understanding your personal risk factors can help you and your doctor decide what prevention and screening steps may be appropriate.
Breast Cancer Risk Factors
Some breast cancer risk factors are outside of your control, while others may be influenced by lifestyle or medical decisions. Having one or more risk factors does not mean you will develop breast cancer, and some people diagnosed with breast cancer have no obvious risk factors.
Common breast cancer risk factors may include:
- Age: Breast cancer risk increases as you get older, especially after age 50.
- Sex assigned at birth: Breast cancer is much more common in women, though men can also develop breast cancer.
- Family history: Having close relatives with breast cancer or ovarian cancer may increase your risk.
- Personal history: A previous breast cancer diagnosis or certain breast conditions may increase future risk.
- Genetic mutations: Inherited gene mutations, including BRCA1 and BRCA2, can significantly increase risk.
- Dense breast tissue: Dense breast tissue can make cancer harder to detect on mammograms and may also increase risk.
- Hormonal history: Early menstruation, later menopause, or certain hormone exposures may affect risk.
Can Breast Cancer Be Prevented?
There is no guaranteed way to prevent breast cancer. Some risk factors, such as age, genetics, family history, and dense breast tissue, cannot be changed. However, certain lifestyle choices may help reduce risk and support overall health.
Ways to support breast health may include:
- Maintaining a healthy weight
- Exercising regularly
- Limiting alcohol
- Avoiding smoking
- Breastfeeding, if possible
- Talking with your doctor about the risks and benefits of hormone replacement therapy
- Keeping up with recommended wellness visits and screening discussions
If you are concerned about your personal risk, your doctor can help you review your health history, family history, and screening options.
Family History, Genetics, and BRCA Risk
Family history can play an important role in breast cancer risk. Inherited mutations in the BRCA1 and BRCA2 genes are strongly associated with hereditary breast and ovarian cancer risk. However, not all breast cancer is inherited, and not everyone with a family history has a known genetic mutation.
You may benefit from talking with your doctor about genetic counseling or testing if:
- Multiple close relatives have had breast cancer or ovarian cancer
- A relative was diagnosed with breast cancer at a younger age
- A male relative had breast cancer
- You have a personal history of breast cancer
- You are unsure whether your family history increases your risk
Genetic counseling can help you understand whether testing may be appropriate and what your results could mean for prevention, screening, and care planning.
Breast Cancer Symptoms and Changes to Watch For
Early breast cancer often does not cause symptoms. That is one reason screening is important. Still, it is helpful to know what changes to report to your doctor.
Talk with a healthcare provider if you notice:
- A lump or thickening in the breast or underarm
- A change in breast size or shape
- Skin dimpling, redness, peeling, or texture changes
- Nipple inversion or nipple changes
- Nipple discharge, especially if bloody or new
- Persistent breast pain or a new area of concern
Knowing what is normal for your body can help you recognize changes earlier. If something feels new, unusual, or concerning, it is worth discussing with your doctor.
Why Early Detection Matters
Breast cancer is often more treatable when it is found early. Screening can help detect breast cancer before symptoms appear, which may give patients more treatment options and improve outcomes.
- For many people at average risk, breast cancer screening discussions begin around age 40.
- Some people may need earlier or additional screening based on family history, dense breast tissue, genetic risk, prior breast findings, or other personal risk factors.
Your doctor can help you understand when to begin screening, how often to be screened, and whether additional imaging or specialist referral may be appropriate.
When Should You Talk to a Doctor About Breast Screening?
You do not need to wait for symptoms to talk about breast health. A primary care provider or OB/GYN can help you review your personal risk and determine the right screening plan.
Consider scheduling a visit if:
- You are age 40 or older and have not discussed mammogram screening
- You have a family history of breast or ovarian cancer
- You have dense breast tissue
- You have had a previous abnormal breast imaging result
- You notice a lump, nipple change, skin change, or new breast symptom
- You are concerned about genetic risk
- You are unsure when to start or continue mammograms
Questions About Breast Cancer Risk or Screening?
A wellness visit can help you review your personal risk factors, family history, breast symptoms, and screening needs. CLS Health providers can help you determine the next appropriate step, whether that includes a clinical breast exam, imaging referral, genetic risk discussion, or specialty care.
How CLS Health Supports Breast Health
Breast health often involves more than one type of care. At CLS Health, patients have access to a connected network of providers who can help with prevention, screening conversations, symptom evaluation, diagnosis, treatment, and ongoing support.
