Breast Cancer Awareness

Breast Cancer Scanning is an important part of Breast Cancer Awareness

Due to the high incidence of breast cancer among older women, screening is now recommended in many countries. Screening methods suggested include breast self-examination and mammography. Only mammography has been proven to reduce mortality from breast cancer. In some countries routine (annual) mammography of older women is encouraged as a screening method to diagnose early breast cancer.

Mammography is still the modality of choice for screening of early breast cancer. Magnetic resonance imaging (MRI) has been shown to detect cancers that are not visible on mammograms, but it has several disadvantages. For example, although it is more sensitive, it is less specific than mammography. It is also a relatively expensive procedure, and one which requires the injection of a chemical agent to be effective. It may be valuable for younger women, whose breasts contain less fat and more connective tissue, making it harder to spot cancers on mammograms. Ultrasound alone is not adequate as a screening tool but it is a useful additional investigation, especially for the characterisation of benign tumours.
