prevention is an important part of healthcare, but it is not a one size fit all program.  as new studies are made prevention medical tests should be adjusted accordingly.   prevention is key as early detection can save  or prolong lives and contain medical costs.  but there is another side to the problem, increasing medical costs - as costs increase more people will not be able to afford prevention screenings.  the answer - universal healthcare to include the training of physicians (government support).  we must also educate the populous about leading healthy lifestyles (active lifestyles and eating healthy), which helps in prevention.
