Breast/Ovarian Cancer Program
We offer genetic counseling and genetic testing to individuals and families who are concerned about their risk(s) to develop breast or ovarian cancer through our Cancer Genetics Program and the Women at Risk Program at Columbia.
A referral to this program may be appropriate if you or a family member have a diagnosis of breast cancer at an early age (usually less than 50), ovarian cancer at any age or a family history of breast or ovarian cancer.
The greater the number of family members you have with these cancers and the younger they were when they were diagnosed and the greater the number of cancers in a single person, the greater the likelihood that there may a heritable susceptibility to cancer within your family.
For women at risk of breast or ovarian cancer we have a team of radiologists, oncologists, breast surgeons, plastic surgeons and gynecological oncologists available for clinical consultation and management.
A consultation with this program provides education about cancer risk, genetic counseling and/or genetic testing, recommendations for cancer risk screening, and the opportunity to participate in research. For further information about this program, please contact us at 212-305-0190.
