A mammogram is an x-ray picture of the breast. Mammograms can be used to check for breast cancer in women who have no signs or symptoms of the disease. This type of mammogram is called a screening mammogram. Screening mammograms usually involve two x-ray pictures, or images, of each breast.

A male swine that is castrated after it has been used for breeding purposes is called a stag. The term pig is often reserved for a young, immature swine in swine farming and it is synonymous with shoat, nursery pig, and grow-finish pig.
