Here's a great article called Shock Study: Mammograms a Medical Hoax . . . by Mike Adams on why mammograms can be dangerous to your health. The comments that follow are almost as interesting than the article. Are mammograms really worth the risks and all the false positives? Too many women undergo procedures and cancer treatments when the risk was minimal. Mammograms miss malignancies far too often and pick up cancer that women of prior generations lived with until they died with no ill effect. Those cancers are called DCIS (ductal carinoman in situ). DCIS is cancer in the milk duct. Cutting into the milk duct can cause the cancer to spread when in most cases the cancer is contained.
Per Mike Adams: "In fact, if you do the math and calculate 0.1 million fewer women with advanced-stage cancer out of 1.5 million who were diagnosed, 93% of the "early detection" cancer cases studied were false positives, meaning that they would never have gone on to cause advanced-stage cancer anyway."
Mike also discusses the cult of Komen Foundation: "Millions of women get innocently swept up into the "run for the cure," apparently clueless to the fact that most of that "cure" money goes to pay for more mammograms that result in more false diagnoses which ensnare yet more women into the same victimization racket." I have to agree. Let's start putting money towards prevention rather than mammograms.
What he doesn't discuss in his article and is an alternative to mammography and that is thermography. Unfortunately, health insurance does not pay for it but is without risks and pain (no smashing of the breasts) and detects precancerous and cancerous conditions years before mammography. It usually cost a couple of hundred dollars.
