October is Breast Cancer Awareness Month
Breast cancer is one of the most common cancers affecting people around the world. Early detection, awareness of risk factors, and access to quality care can make a significant difference in outcomes.
Breast Cancer Awareness Month
October is Breast Cancer Awareness Month — a time to educate, support, and raise awareness about one of the most common cancers worldwide. Early detection saves lives, and awareness can empower people to take control of their health through regular screenings and informed choices.
What Is Breast Cancer?
Breast cancer occurs when cells in the breast begin to grow uncontrollably, forming a tumor. These cells can stay contained (in situ) or become invasive, spreading into surrounding tissue and possibly to distant parts of the body (metastasis).
It is the most commonly diagnosed cancer in women globally (other than skin cancers), and a leading cause of cancer death among women, though outcomes have greatly improved in many places due to advances in screening and treatment.
Breast cancer can also occur in men, though much more rarely (approximately 0.5–1% of cases).
Risk Factors & Prevention
Breast cancer risk is influenced by a combination of factors—some we can control, many we cannot.
Non-modifiable risk factors include:
- Being female and growing older (age is among the strongest risk variables)
- Family history of breast cancer, especially in first-degree relatives (mother, sister, daughter)
- Inherited gene mutations such as BRCA1, BRCA2, and PALB2
- Hormonal and reproductive factors (for example, early start of menstruation, late menopause, not having children or having late pregnancies)
- Previous exposure to radiation to the chest (e.g. for prior cancer)
Modifiable factors / risk reduction strategies may include:
- Maintaining a healthy body weight and physical activity
- Limiting alcohol consumption (even low to moderate alcohol intake is associated with incrementally higher breast cancer risk)
- Avoiding or being cautious with hormone replacement therapy (HRT) when possible (especially combined estrogen-progestin therapy)
- Breastfeeding, which has been shown to modestly reduce risk in some people
- While many risk factors cannot be changed, being aware of your risk and working with your medical provider to tailor a screening or prevention plan is key.
Recognizing the Signs and Taking Action Early
Breast cancer can appear in different ways. Common signs to watch for include:
- A new lump or thickened area in the breast or underarm
- Changes in breast size, shape, or appearance
- Unexplained nipple discharge (especially if bloody)
- Skin changes such as redness, dimpling, or puckering
- Nipple turning inward or pain in the breast area
Not all changes mean cancer — but any new or unusual symptoms should be checked by a healthcare provider.
Early Detection
Early detection saves lives. Simple habits and screenings can make a big difference:
- Perform regular breast self-exams to become familiar with your normal look and feel
- Schedule annual mammograms starting at the age recommended by your doctor
- Keep up with routine check-ups and discuss your family health history
- Report any changes to your doctor right away
Being proactive about your breast health gives you the best chance for early diagnosis and successful treatment.
Treatment & Care Options
Treatment depends on the type and stage of cancer, but often includes a combination of:
- Surgery (lumpectomy or mastectomy)
- Radiation therapy
- Chemotherapy
- Hormone or targeted therapy
- Supportive and survivorship care
Today, many people live long, healthy lives after breast cancer, especially when it’s caught early.

Frequently Asked Questions
Understanding breast cancer can feel overwhelming, but having clear, reliable information can make a big difference. Below are answers to some of the most common questions about breast health, detection, and support.
-
How often should I get a mammogram?
Most experts recommend that women with average risk begin annual or biennial mammograms at age 40–45. However, personal and family medical history can change that timeline. Talk to your healthcare provider about the right screening schedule for you.
-
Can men get breast cancer?
Yes, although it’s rare. About 1 in 100 breast cancer diagnoses in the U.S. occurs in men. Because awareness is lower, men often get diagnosed at a later stage, making early attention to any changes in the chest area especially important.
-
If I have no family history, am I still at risk?
Yes. Most people diagnosed with breast cancer have no family history of the disease. Family history increases risk, but lifestyle, hormonal, and environmental factors can also play a role.
-
What should I do if I notice a breast change?
If you find a new lump, skin change, or discharge, contact your healthcare provider right away for evaluation. Most breast changes are not cancer, but only a medical professional can determine the cause.
-
How can I support someone going through breast cancer?
Offer emotional support, practical help (like meals or rides to appointments), and a listening ear. Encourage them to connect with survivor networks or organizations that offer financial and emotional resources for patients and families.
