I am getting conflicting reports from my medical team and reading research studies. old data vs new data: are all neuroendocrine tumors now categorized as malignant?

Neuroendocrine tumors are not all the same and their behavior depends on the morphology and anatomic location. You will get different opinion/information depending on the type and location of the tumor. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
