Clinical trials, like every other part of cancer treatment need to be fully ubderstood before going inot them. They and be a godsend or nightmare depending on the circumstances. Some trials have control groups that get a placebo instead of treatment others everyone gets treatment. Once a trial is done it can become very difficult to get, the drug even if it worked wonders for you, until full FDA approvals are recieved. Some insurance companies don't play well with trials. On the other hand you might be the first person cured of cancer by the drug.
With any part of cancer treatment you need to ask lots of questions and get all of the information on the trial you can get. Know what the drug promises, know how the trial is set up. What is expected of you to participate in the trial onbce you have all of the information and understand it you can then with the help of your Doctors make and informed decision. Good luck and let us know if you can help in any way!
