part of a comprehensive genetic analysis of breast cancer. among other discoveries, researchers say that a rare but deadly form of breast cancer bears a genetic resemblance to the kinds of tumors found in lung and ovarian cancers. doctors also learned that the two most common forms of breast cancer, both of which rely on estrogen to fuel their growth and have been similarly in the past, are actually genetically distinct from one another. for more on this, i'm joined by dr. harold varmus. he's director of the national cancer institute. the institute has helped to lead the work as part of a larger project to map genetic changes in cancer. dr. varmus, thank you for being here. >> my pleasure. woodruff: tell us what is significant about what you found about these four types of breast can iser. >> these four types have actually been known for some time based on work done nearly a decade ago that was intent on characterizing which genes were off and on in breast cancer types. to the surprise of many, it was possible to form four large groups that m

i was stunned, i thought breast milk was as pure as it came for food source. i was up all night thinking about it. i tell the story about michelle from california whose family was the first family to be monitored in the oakland tribune. it stunned even scientists. the tests found many of the same chemicals they found in charlotte's 5-year-old mic ala, she had recently spent a lot of time in nail salons. the biggest surprise of what they found in 2-year-old rowland, chemicals found in nearly anyone else in the world 6 times higher than in parents, twice the levels that researchers see in land animals. this is a serious warning said a scientist researchers on flame retar tkapbts. young children are exposed because they put their hands in their mouth and bodies don't eliminate chemicals as readily. to me i think very historically crystallizes what we are learning. that was a story in 2006 by the environmental working group where they analyzed the umbilical cord blood of newborn babies and found an average of 200 chemicals found to be toxic in every single baby, m

those women are at much higher risk of breast cancer. these women with an ult arfamily history, they get tested, they carry the gene, they were getting mammograms often before 30. what the new research found out in britain is those women that get mammograms, that increases their risk of getting breast cancer because of the radiation. that causes cell damage. they already can't repair the cell damage. for these women in a small group, not a huge group, they should get mris and avoid mammograms, avoid chest x-rays and ct scans if they're younger because any radiation exposure is going to increase their risks. >> so maybe for them, mammograms should begin after 35? they're doing mris until that point? >> they should avoid radiation exposure and for screening for these women, mris are probably going to be the better test. >> fascinating stuff. you did clear the air. thank you so much. appreciate it. >> and every saturday at this time, we bring you new information about medical breakthroughs or ways to improve your health and quality of life.
