The endocrine system is made up of specialized glands and cells that produce chemical messengers (hormones) that control cell and organ function. Endocrine tumors involve specific cells found only in this system.
Endocrine tumors may arise in the thyroid, parathyroid, adrenal gland, pancreas, or intestine and can present a range of treatment challenges. They can be benign (noncancerous) or malignant (cancerous) and can affect your body’s hormone production. Some of these tumors may be slow-growing, and others may behave more aggressively. Some cause symptoms by producing hormones, while others cause symptoms through growth or spread to distant parts of the body.
Despite this complexity, endocrine tumors all share important underlying traits, because they are all part of the body’s hormone-regulating system.
Our unique clinic—dedicated exclusively to treating these tumors—brings together specialists in endocrinology, endocrine surgery, medical oncology, nuclear medicine, and other fields. As a team, we provide customized treatment planning and care for your individual needs.
We use advanced diagnostic techniques to identify and understand your condition. Our precise laboratory workups, surgery, and genetic testing pinpoint the best course of action.
Did you know?
Endocrine cancers are diagnosed in more than 35,000 people in the U.S. each year. The majority are thyroid cancers, which affect three times as many women as men.
Thyroid Disease
A butterfly-shaped gland at the base of the neck, the thyroid is the body's master metabolic control center. It helps regulate heart rate, weight, energy levels, body temperature, growth, and muscle strength.
We partner closely with our Endocrinology Clinic to provide the right care for your needs, including comprehensive medical and surgical care for thyroid tumors and management of hormone imbalances.
Benign thyroid disease
Thyroid nodules are common, and 95% are benign (noncancerous).
- Thyroid nodules
- Multinodular goiter
- Hyperthyroidism, including Graves’ disease
- Papillary thyroid carcinoma
- Follicular thyroid carcinoma
- Hurthle cell carcinoma
- Medullary thyroid carcinoma
- Poorly differentiated and anaplastic carcinoma
- Thyroid lymphoma
Adrenal Tumors
The adrenal glands are small glands located above the kidneys. They produce hormones that help the body react to stressors and control blood sugar and blood pressure.
Adrenal tumors can be challenging to identify and treat. Through our expertise, we assess tumors accurately to ensure that you receive the appropriate treatment.
Should you need surgery, we have extensive experience in minimally invasive and open procedures. We provide genetic counseling to find the cause and help guide your next steps. We also partner with our Hypertension Center for diagnosis and treatment of adrenal tumors that affect the blood pressure.
- Adrenocortical carcinoma
- Aldosterone-producing adrenal tumor
- Pheochromocytoma or paraganglioma
- Cortisol-producing adrenal tumor (Cushing’s syndrome)
- Incidentally discovered adrenal tumor (adrenal incidentaloma)
- Metastatic tumor to the adrenal gland
Parathyroid Disease
The four parathyroid glands are located near the thyroid gland, in the central part of the neck. Parathyroid tumors are nearly always benign (noncancerous). Because these glands control the body’s calcium levels, parathyroid tumors may cause osteoporosis (reduced bone mass), kidney stones, and other serious complications.
Doctors around the U.S. refer patients with parathyroid disorders to us. They rely on our leading expertise in diagnosis, surgical planning, and minimally invasive techniques. We partner with our Osteoporosis and Metabolic Bone Diseases Clinic to manage bone complications associated with parathyroid disease.
Hyperparathyroidism and parathyroid disorders:
- Primary Hyperparathyroidism
- Secondary and tertiary (renal) hyperparathyroidism
- Genetic syndromes associated with hyperparathyroidism (MEN1 and 2)
- Parathyroid cancer
- Persistent or recurrent hyperparathyroidism
Neuroendocrine Tumors
Neuroendocrine cells are specialized cells that release hormones into the blood in response to signals from the nervous system. Neuroendocrine tumors (NETs) are uncommon and often slow-growing.
Our established program has extensive expertise in managing NETs of the pancreas and GI tract both at initial diagnosis and through ongoing follow-up. We partner closely with you to offer a personalized care plan for your long-term health.
- Pancreatic neuroendocrine tumors
- Gastrinoma
- Glucagonoma
- Insulinoma
- VIPoma
- Hormonally inactive tumors
- Small intestine neuroendocrine tumors
- Neuroendocrine tumors of unknown primary site
Our partner clinics care for people with NETs elsewhere in the body:
- Thoracic Cancer Program manages neuroendocrine lung cancer.
- Skin Cancer Program treats Merkel cell carcinoma.
- Brain Tumor Center cares for patients with pituitary tumors.
Stanford doctors are internationally recognized experts in endocrine conditions, from common tumors to rare and difficult-to-diagnose endocrine cancer.
We combine our high level of diagnostic and treatment expertise with advanced imaging technologies and lab workups to pinpoint the most appropriate therapies for you. When surgery is the best option, our surgeons are nationally recognized for their expertise in both open and precise minimally invasive procedures.
INNOVATION HIGHLIGHT
Our doctors study endocrine tumors to identify new ways to predict tumor development and treat existing tumors. They recently discovered new pheochromocytoma genetic syndromes, which may reveal new ways to diagnose and treat these tumors more precisely.
Treatments by Condition
We create an individualized treatment plan for you, based on your precise needs. We’ll plan your care based on biopsy results, genetic testing, your desires, and your symptoms. At weekly Tumor Board meetings, experts from multiple disciplines review cases that require more complex recommendations.
Every care path starts with a thorough assessment to understand a tumor’s precise anatomy and function. We use advanced tests to find the cause and identify treatment that will be most effective for you.
We perform surgery for:
All Treatments
When it comes to care for endocrine tumors, you’ll benefit from our extensive expertise in the latest treatment options. While surgery is often a first treatment, some conditions require different care. Your care plan will be customized to your needs and may include one or a combination of the following treatments:
Surgery for endocrine disorders and tumors
Our surgeons have advanced training in the care of benign and cancerous tumors and are nationally recognized for their expertise. They offer extensive experience in complex operations and minimally invasive procedures, which minimize scarring and pain.
- Surgery for thyroid tumors
- Surgery for adrenal tumors
- Surgery for hyperparathyroidism and parathyroid tumors
- Surgery for gastrointestinal and pancreatic neuroendocrine tumors (NET)
Radioactive iodine
Because the thyroid gland absorbs iodine, radioactive iodine can treat thyroid conditions with only a minor effect on the rest of your body. It can destroy all or part of the thyroid gland, as with hyperthyroidism. It also may be used to treat papillary or follicular thyroid cancer and some other tumors.
Active surveillance
For slow-growing, small, noncancerous tumors or low-grade cancers, we may recommend active surveillance (watching the tumor but not yet treating it).
Additional Treatments
As part of the Stanford Cancer Center, the Endocrine Tumor Program offers comprehensive cancer care—including the latest medical therapies, radiation techniques, and cancer genetics. Our experts will work with you to design the best care plan for your needs and lifestyle.
Medical therapy
In medical therapy, you take medications by mouth, through a vein by IV (intravenous) infusion, or by injection. These medications travel through your body to attack cancer cells. We offer:
Genomic tumor profiling
Our dedicated cancer genetics doctors test tumor cells to identify a tumor’s particular genetic fingerprint. These results help us predict which treatments will be most effective for a given tumor and identify novel targeted therapies.
- External beam radiation
- 3D conformal radiation therapy
- Intensity-modulated radiation therapy
- Stereotactic ablative radiation therapy (SABR/SBRT)
Treatment for NET metastasis to liver
Sometimes, neuroendocrine tumors (NETs) metastasize, or spread, to the liver. We offer specific treatments to kill tumor cells directly or block blood flow to the tumor, including:
- Radiofrequency ablation
- Hepatic artery embolization
Genetic Counseling
Many people who develop endocrine tumors have inherited genetic syndromes. Our dedicated cancer geneticists have special training in the genetics of endocrine tumors and in the best ways to help you assess your family’s risk. Test results can guide treatment, identify affected family members, and help with family planning.
We frequently treat multiple endocrine neoplasia (MEN1 and MEN2), syndromes of multiple endocrine tumors that are passed down in families. Our services help evaluate for the following genetic syndromes:
Multiple Endocrine Neoplasia Type 1 (MEN1)
This genetic disorder is associated with a lifetime risk for:
Multiple Endocrine Neoplasia Type 2 (MEN2)
This genetic disorder can lead to:
- Medullary thyroid carcinoma and its precursor, C-cell hyperplasia
- Pheochromocytoma (PHEO)
Other syndromes associated with endocrine disease
- Beckwith-Wiedemann syndrome
- Familial adenomatous polyposis (FAP)
- Li-Fraumeni syndrome
- Lynch syndrome
Clinical Trials
As a Stanford Health Care patient, you may be eligible to participate in open clinical trials. Open trials refer to studies that are currently recruiting participants or that may recruit participants in the near future. Closed trials are not currently enrolling, but similar studies may open in the future.
Your Care Team
Your care team will be customized to your needs and the type of endocrine tumor you have. You may receive care from an endocrinologist and a specialized surgeon. Or a medical oncologist may oversee your care. We will coordinate your care among the most appropriate providers from these specialties:

So that you receive the right care from an integrated group of providers, our Endocrine Tumor Program has close clinical partnerships with Stanford’s:
Stanford is an Academic Medical Center, which is a type of hospital setting where doctors teach the entire spectrum of medical education. Students range from beginning medical students to fully licensed and practicing doctors completing advanced sub-specialty training. Stanford Medicine is a partnership between Stanford University School of Medicine and Stanford Health Care. Since Stanford is a teaching hospital, you can expect to meet many providers and providers in training.
- Attending Physician: a doctor who supervises doctors in training or in medical school
- Fellow: a doctor doing postgraduate level work and specializing in care of patients with specific conditions
- Resident: a doctor who has graduated from medical school and is in training (also called “residency”) here at Stanford. A resident is also called an intern
- Medical Student: a student who is currently enrolled in medical school with the goal of becoming a doctor
Extended Care Team
Our oncology-certified health care provider works with your oncologist to help with diagnosis and treatment. APPs may recommend medications, lifestyle changes, and services such as genetic counseling. An APP can be a nurse practitioner (NP), physician assistant (PA), or clinical nurse specialist (CNS).
ADVANCED PRACTICE PROVIDERS
Our genetic experts can help you and your family understand any inherited risk for endocrine tumors or other cancer. They explain and provide available genetic tests. They can also discuss prevention, screening, and treatment options.
Our radiation therapists deliver radiation according to the plan developed by your radiation oncologist and other team members.
Our medical physicists monitor and calibrate our treatment equipment and oversee the quality of the treatments that are delivered.
These registered nurses provide one-on-one support throughout your care journey. They help you navigate from your first contact with us to follow-up care, assessing your needs, answering your questions, making referrals, coordinating appointments, and providing education.
Care coordinators provide you with information and assistance before and during your appointments.
- Medical Assistants take you to your exam room after you check in for your appointments. They check your vital signs before your doctor sees you.
- New Patient Coordinators contact you before your first appointment and help you prepare by providing the information you need to know and bring with you.

- ITA Schedulers schedule your appointments if you have apheresis (a specific type of blood transfusion) or chemotherapy.
- Surgery Schedulers call you to arrange the details for meeting with a surgical oncologist or reconstruction surgeon or for having surgery.
Many people with complex parathyroid tumors will experience osteoporosis (bones becoming brittle). Specialists from our Osteoporosis and Metabolic Bone Diseases Clinic can help manage this side effect of hyperparathyroidism to protect your bone health.
Nutritionists work with you to establish an eating plan that meets your nutritional needs and takes into account the challenges of living with an endocrine tumor. They are an important part of the long-term care plan to help people with neuroendocrine tumors (NETs) manage the condition.
After thyroid surgery, some people have difficulty with their voice and swallowing. Speech pathologists use their training to help restore pre-operative vocal and speech abilities.
These specially trained physical therapists support people who have undergone thyroid surgery. They work with people to relieve vocal cord problems, anxiety, and strain related to treatment or resulting scar tissue.
If you qualify for a clinical trial, our research coordinators guide you through the process. They educate you about what to expect during the study, answer your questions, and schedule your appointments.
