Breast Cancer Early Detection and Diagnosis

Breast cancer is sometimes found after symptoms appear, but many women with breast cancer have no symptoms. This is why regular breast cancer screening is so important. Learn more.   

Can Breast Cancer Be Found Early?

Breast cancer is sometimes found after symptoms appear, but many women with breast cancer have no symptoms. This is why regular breast cancer screening is so important. Learn more.   

  • American Cancer Society Recommendations for the Early Detection of Breast Cancer

Imaging Tests to Find Breast Cancer

Different tests can be used to look for and diagnose breast cancer. If your doctor finds an area of concern on a screening test (a mammogram), or if you have symptoms that could mean breast cancer, you will need more tests to know for sure if it’s cancer. 

  • Mammograms
  • Breast Ultrasound
  • Breast MRI
  • Newer and Experimental Breast Imaging Tests

Biopsy

A biopsy is done when mammograms, other imaging tests, or a physical exam shows a breast change that may be cancer. A biopsy is the only way to know for sure if it’s cancer. 

  • Breast Biopsy

Tests to look for breast cancer spread

If your doctor suspects your cancer may have spread to other parts of your body, you may need more tests, such as chest x-rays, CT scans, bone scans, PET scans, or MRI scans. 

  • Imaging Tests to Find Out if Breast Cancer Has Spread

Finding breast cancer during pregnancy

Breast cancer during pregnancy is rare. But if you find a lump or notice any unusual changes in your breasts that concern you, tell your doctor or nurse right away.
