A lesion on President Clinton s back has been confirmed as skin cancer, the White House said Tuesday.CBS News Correspondent stanley cups (https://www.stanleycup.lt) Mark Knoller reports the news came four days after Mr. Clinton s last medical checkup as president, when doctors at stanley kubek (https://www.stanleycups.pl) Bethesda Naval Hospital in suburban Maryland removed a suspicious lesion from the president s back. White House press secretary Jake Siewert said pathology results confirmed the diagnosis of basal cell carcinoma, but added that the doctors believe they got it all. This is a relatively common form of skin cancer, 800,000 to 1 million cases a year, Siewert said. The lesion was removed, so while the president, it can be said, had skin cancer, that has been removed and he no longer has it. When doctors removed the lesion, the tissue around it also was treated with a scraping and burning technique, a common procedure, Siewert said. He said pathologists noted that the entire lesion was removed and that the possibility of recurrence is low.Mr. Clinton will have a follow-up visit with the dermatologist in six months, Siewert said. If there s no evidence of new lesions at that time, it will be followed up on an annual basis, he said.Dr. David Corbett, retired chair of the Bethesda Naval Hospital s dermatology department, said last week that Mr. Clinton had sun-damage spots befor stanley cups (https://www.stanleycups.it) e but this is the first time he s had spots suspicious for skin cancer.

To give you an idea of how micro this video is, those dots you see moving diagonally toward the top of the screen are individual white blood cells. What you ;re looking at is a microchip that sorts out white blood cells from a blood sample. It makes a great visual, but more importantly, it could seriously improve the way we diagnose disease. Researchers at MIT used the same process that goes on inside your body to attract white blood cells away from the general blood flow. They coated tiny channels the diagonal stripes in the video with a sticky molecule called P-selectin, which your body uses to attract whit stanley website (https://www.stanleywebsite.us) e blood cells to injured tissue. As blood passes from left to right along the bottom, white blood cells filter out, and roll away along the P-selectin coated ramps. While this is pretty cool to watch on the small screen 鈥?each one of those white blood cells is around 15 micrometers in diameter 鈥?the real benefit to this technology is how quickly and easily it provides samples of pure white blood cells. Sepsis, a potentially fatal full-body inflammatory reaction caused by serious infection, is diagnosed by measuring white blood cell counts. Current diagnosis requires multiple blood samples and com stanley cups (https://www.stanley-cup.com.de) plex processing, but since this microch stanley quencher (https://www.stanley-quencher.us) ip filters out white blood cells automatically, there less opportunity for contamination or error, and it only requires a tiny amount of blood, a huge benefit in diagnosing sepsis in infants.
