Not to take anything away from local docs or even local cancer specialists but they can’t possibly have the breadth of knowledge and experience as you will find at a cancer centre where they have seen and treated everything. According to MD Anderson data 25% of the people they treat come in with wrong pathologies from original doctor—not to mention many more who should have been diagnosed a lot earlier. Cancer is such a diverse spectrum of diseases that you really need to look for the leading medical professionals in whatever unique area of expertise you need. Mostly you will find them at a specialty cancer clinic. As a previous commenter posted it is easy and quick to get into MD Anderson. All you need is to have your pathology sent to them. Some local docs will directly refer if wanting to get a diagnosis and/or treatment plan confirmed. They will treat or just provide their expertise for you to be treated elsewhere. I am sure there are excellent resources at other well known specialty clinics. Don’t want to take anything away from them, but just commenting from personal experience as a caregiver to a patient. By the way, MD Anderson treats caregivers as royalty!
