A mammogram is conducted by a specialist to trace any abnormal changes in the breasts that indicate the presence of cancerous tissues. A mammogram is essentially an x-ray. The doctor will look to find patterns in the changes happening in the breasts. These changes could be calcification, lumps or masses or other changes that may indicate cancer.

A mammogram is advised on a yearly basis so that the doctor can have a historic record of the changes in your breasts and can make informed decisions on the risk of developing cancer. It is important to discuss factors such as surgery, family history, previous occurrence of breast cancer or other forms of cancers to your doctor for improved accuracy of the mammograms.
