Genetic and genomic testing enables the examination of DNA and assists in determining susceptibility to inherited diseases. Genetic testing for cancer predisposition has traditionally been done by looking at one gene at a time. With advances in technology, multiple genes can be evaluated in parallel through one test — this is referred to as panel testing or multiplex testing. New technologies such as whole genome or exome testing (evaluation of the complete set of DNA) of a person or a tumor may identify hereditary cancer predisposition.
Our Specialty Centers and Programs
Clinicians in our specialty centers and programs provide state-of-the-art care, while helping patients and families to understand their cancer risk and suggest ways to lower risk.
We partner with medical oncologists and gynecological oncology surgeons, geneticists, and genetic counselors to evaluate your personal or family history of breast and ovarian cancers and other associated cancers. Patients learn what steps they can take
to reduce their risk of developing breast and ovarian cancer.
Colorectal cancer can run in families, and about 5 to 10 percent of colorectal cancer is thought to be hereditary. We offer advanced genetic testing to determine an individual's risk for colorectal cancer. Our practice follows patients who have an increased
risk for polyps, colorectal cancers, gastrointestinal cancers, Lynch syndrome, and related cancers. We also offer risk assessment and genetic testing for individuals who may be at increased risk for pancreatic cancer and determine eligibility for
Lynch syndrome is a genetic condition that increases the risk of certain cancers. The Lynch Syndrome Program specializes in coordinating the care of people with Lynch syndrome. Our specialists act as quarterbacks, by creating personalized management plans
for people who have Lynch syndrome. Lynch syndrome is a multi-organ disease associated with colon, uterine, and pancreatic cancer among others, and we ensure careful monitoring and managing the disease to prevent each of these cancers in our patients.
We offer heightened surveillance using whole body MRI, and the opportunity to participate in other research studies. We collect information about individual and family cancer history and collect specimens from patients and family members with Li-Fraumeni
Syndrome. We collaborate with the International Li Fraumeni Consortium to hasten new knowledge.
Hereditary Paraganglioma-Pheochromocytoma Syndrome (PGL/PCC)
The Paraganglioma-Pheochromocytoma Genetics Group is a collaborative initiative of Dana-Farber's Cancer Genetics and Prevention Program and Brigham and Women's Endocrine Division – with endocrinologists, geneticists, oncologists, and genetic counselors
dedicated to providing patients with personalized hereditary risk evaluation, genetic testing, recommendations for screening and prevention, and long-term follow-up.
Gastrointestinal Stromal Tumors (GIST)
By looking at the genes of people with GIST, we have learned about inherited forms of GIST and how best to monitor individuals at high genetic risk.

Screening procedures that we would be happy to assist in scheduling at Dana-Farber Cancer Institute or Brigham and Women's Hospital include:
- Colonoscopy: A test that allows the clinician to see the large intestine
- Endoscopy: A type of screening that uses a lighted instrument (endoscope) to examine the interior of hollow areas or organs within the body
- Endoscopic ultrasound: A combination of ultrasound and endoscopy that allows the collection of images about the digestive tract
- Endoscopic retrograde cholangiopancreatogram (ERCP): A test that uses a lighted scope (endoscope) to examine the tubes that drain the liver, gallbladder, and pancreas
- Mammogram: An x-ray of the breast
- Magnetic resonance cholangiopancreatography (MRCP): A technique that uses
magnetic resonance imaging to see biliary and pancreatic ducts
- MRI / breast MRI: A technique used to see internal structures of the body in detail. This type of imaging provides contrast and enables detailed images of the
- Ultrasound / transvaginal ultrasound: Screening used to detect objects or see distances
