The decision to undergo treatment resides completely with you and your family. Many cancers, when caught early, are highly treatable, allowing patients to live years and even decades beyond their initial diagnosis. Patients with advanced cancer may be eligible for enrollment in a clinical trial (study) that offers investigational new treatment not available to most patients. A decision about whether or not to have treatment should be made after discussions with your family, your doctor, and after carefully weighing all the options available to you.
