Should I talk to my doctor about my endocrine cancer symptoms?

See a doctor if you have any worrisome symptoms. The symptoms of endocrine cancers can be vague and general (such as headache and weight loss), and they can vary widely depending on the specific endocrine gland involved. For example, the pituitary gland regulates a wide variety of body processes, so a pituitary tumor could cause any of dozens of seemingly unrelated symptoms, from vision problems to decreased interest in sex.
