A congressional advisory panel released a study today reporting “old-fashioned” mammograms to be the most effective and reliable method of detecting pre-cancerous lumps in women’s breasts. The panel found that none of the newer technologies, such as digital mammograms, MRI or testing breast fluid, were as reliable as the traditional X-ray mammogram. American women undergo 30 million mammograms every year. The exam can reduce cancer deaths by 25 to 30 percent. Mammograms cost between 75 and 150 dollars and most are covered by insurance. The Centers for Disease Control and Prevention offers free mammograms to uninsured women.
