Full Body Scan Raises Cancer Risk

b>High Systolic Blood Pressure should be Treated

In a pooled analysis of 1,064 studies done between 1996 and 2004 researchers say that elevated systolic blood pressure (the top reading greater than 160mmhg) should be treated especially with calcium channel blocking agents or Thiazide diuretics. This is to decrease the risk of developing heart disease or a stroke. They are not yet sure if life style changes would be sufficient to lower the reading or if a reading of 140 to 160 should be treated. The study is in the September 1st issue of the Journal of the American Medical Association.

If you are using a whole-body X-ray scan to detect tumors at their earliest stage you are likely increasing the risk of developing cancer according to a new study. A whole-body X-ray or CT scan involves multiple X-rays at multiple angles pieced together into a 3-D image by a computer for a detailed picture. Columbia University radiologist-oncologist David Brenner states, "The radiation dose from a full-body CT scan is comparable to the doses received by some of the atomic-bomb survivors from Hiroshima and Nagasaki, where there is clear evidence of cancer risk". The dose from a single full-body CT scan is comparable to the doses received by some of the atomic bomb survivors and is 100 times that of a typical mammogram. They estimate this will cause cancer in one in 1,200 people. The study is in the September 2004 issue of the journal Radiology.
