What does breast cancer look like on an xray?

Variable appearance: On a mammogram cancer can look like a white irregular density or can appear as small specks of calcium (microcalcifications) clumped in a particular pattern. Sometimes cancers show both features. It is important to remember that not all densities or microcalcifications seen on mammography are cancer. Only a biopsy can confirm that cancer is present.

Several ways: On a mammogram, breast cancer can look like a mass or angry star with spicules/spikes emanating from it. It can be very subtle and just cause some mild distortion of the normal tissue. It can also present a microcalcifications. These look like small white flecks on the mammogram and could represent cancer within the milk ducts. It can also just look like extra density on one side.
