Leaders in Cancer Genetics

Stanford's Cancer Genetics Program doctors and researchers have been instrumental in developing many of the leading technologies used to understand, diagnose, test and screen for hereditary cancer syndromes. This expertise allows our specialists to offer you personalized plans for managing your cancer risk.

Our Doctors

Care and Treatment of Hereditary Cancers

Hereditary Cancer Syndromes

Adrenal cancer

A very rare type of cancer that affects the adrenal glands (located above each kidney in the back of the upper abdomen). 

Ataxia telangiectasia (A-T)

A gene mutation that potentially give a small predisposition to develop breast cancer. 

Basal cell nevus (Gorlin syndrome)

A rare genetic syndrome involving the skin, nervous system, eyes, endocrine glands, and bones.

Cowden syndrome

A rare inherited disorder characterized by a range of non-cancerous lesions and an increased risk of certain forms of cancer.

Familial adenomatous polyposis (FAP)

A genetic condition in which hundreds or thousands of colorectal polyps develop mainly in the colon and rectum, leading to a very high risk of colorectal cancer.  There is also higher risk of small intestine and thyroid cancer.


A tumor in the pancreas or duodenum; may occur as part of a hereditary endocrine syndrome. Gastrinomas secrete above average levels of gastrin, a hormone that stimulates the stomach to secrete acids and enzymes. Gastrinoma can cause peptic ulcers.

Hereditary breast/ovarian cancer syndrome

Hereditary breast ovarian cancer (HBOC) syndrome is characterized by early age of onset of breast cancer (often before age 50), family history of both breast and ovarian cancer, an autosomal dominant pattern of inheritance, or an increased incidence of tumors of other specific organs, such as the prostate.

Hereditary diffuse gastric cancer (HDGC)

A genetic cancer susceptibility syndrome characterized by a high risk for stomach and lobular breast cancer.

Hereditary nonpolyposis colorectal cancer (HNPCC)

Also known as Lynch syndrome, a genetic condition with a high risk of colon and other cancers.


A rare pancreatic tumor that secretes insulin, the hormone that lowers glucose levels in the blood. Often a genetic condition that runs in families.

Juvenile polyposis syndrome

A genetic disorder characterized by multiple noncancerous (benign) growths called juvenile polyps, usually developing in children or young adults.

Li-Fraumeni syndrome

A familial genetic syndrome with a highly increased risk for multiple cancers.

Lynch syndrome (HNPCC)

Previously known as Hereditary Nonpolyposis Colon Cancer (HNPCC), Lynch syndrome predisposes people to develop colorectal, uterine, ovarian and stomach cancers, as well as other cancers.

Male breast cancer

A rare form of breast cancer, with less than 1% of all breast carcinomas occuring in men. Breast cancer usually presents as a new lump or mass in a man's breast. While many facilities treat this with mastectomy, Stanford has successfully treated male breast cancer with lumpectomy.

Medullary thyroid cancer

Medullary thyroid cancer is a type of cancer that originates in the parafollicular cells (C cells).

Multiple endocrine neoplasia (MEN)

An inherited syndrome characterized by benign or malignant endocrine glands.

Parathyroid cancer

A rare cancer of the parathyroid glands; often a genetic condition that runs in families.

Pituitary cancer

A cancer of the pituitary gland; often a genetic condition that runs in families.

Peutz-Jeghers syndrome (PJS)

A rare early-onset disorder associated with specific physical characteristics in addition to increased gastrointestinal, breast, pancreas and ovarian cancer risks.

Thyroid cancer

A fairly common type of cancer found in the tissues of the thyroid gland, located at the base of the throat.

Von Hippel-Lindau syndrome

A hereditary condition associated with blood vessel tumors of the brain, spinal cord, and eye.


Cancer in the Family

Many people have relatives with cancer but when should you be concerned about a genetic cancer risk? Who might benefit from genetic testing and how is it done?

Clinical Trials

Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you have access to the latest, advanced clinical trials.

Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.

Before beginning treatment, ask your doctor about any clinical trials you should consider. Learn more about clinical trials for cancer patients.

For Patients


Review the New Patient Packet for information about:

  • What to expect on the day of your appointment
  • Maps, directions, parking, public transit options, and contact information
  • Other patient resources

Bring completed forms found in the New Patient Appointment Letter and Pre-Visit Questionnaire.


See the BRCA Decision Tool which guides the management of cancer risks for BRCA1 and BRCA2 mutation carriers.


Please fax the Medical Record Release Form to your new patient coordinator. The medical release form is an authorization form for external facilities to release medical records to Stanford Health Care (formerly Stanford Hospital & Clinics).
