October is Breast Cancer Awareness Month 2025. This annual campaign raises awareness about breast cancer, promotes early detection, and provides support for people affected by the disease.

What is Breast Cancer Awareness Month?

Breast Cancer Awareness Month is observed every October worldwide. It focuses on:

  • Educating about breast cancer risk factors and prevention
  • Promoting screenings like mammograms for early detection
  • Supporting patients, survivors, and families
  • Raising funds for research and treatment

Why early detection matters

Early detection of breast cancer can save lives. Regular mammograms, self-exams, and checkups increase the chances of finding breast cancer at an earlier, more treatable stage.

What are the symptoms of breast cancer?

Common signs and symptoms may include:

  • A lump in the breast or underarm
  • Changes in breast shape or size
  • Skin dimpling or redness
  • Nipple discharge or pain

If you notice any changes, it’s important to contact your healthcare provider.

How to reduce risk

While not all breast cancer can be prevented, you can lower your risk by:

  • Maintaining a healthy weight
  • Exercising regularly
  • Limiting alcohol consumption
  • Talking to your doctor about family history and genetic testing

How you can support Breast Cancer Awareness Month

  • Schedule a mammogram if you’re due for screening
  • Share resources to raise awareness in your community
  • Donate or volunteer with organizations funding research and patient support
