Large clinical trials are required to prove that a new drug or treatment is effective.  Without such proof doctors will not (and should not) believe that any particular medicine or device is effective.  The FDA also approves drugs by evaluating results of large trials, usually involving hundreds if not thousands of participants.  If you want to help these new treatments to become available you should consider participating in such study.  In addition to feeling good about helping science and possibly your descendants, you may also benefit from a free evaluation and treatment.  Of course, there are risks associated with new treatments and the researchers are required to explain them to you in great detail.

One of the reasons for this post is to let you know about a new website which makes finding a clinical trial very easy.   You can search these trials by disease, location, and other criteria.  The site is http://www.medpedia.com/clinical-trials.  Check it out.
