Diagnosis of breast cancer at an early stage when the symptoms are not yet visible is done through a procedure called mammography. A mammogram is an x-ray image of the breast taken using the procedure. It can be used to diagnose for breast cancer in women who have no signs or symptoms of the disease but are at increased risk. It can also be used if a woman notices a lump or bump or any other sign of breast cancer in any of the breasts. Screening using mammography is a type of mammogram that checks you when you have no symptoms.

Breast self-exam (BSE), or regularly examining the breasts on your own, can be an effective way to find breast cancer in early stage, when it's more likely to be treated successfully.
