Our Approach

The Cancer Genetics Clinic at The Children's Hospital of San Antonio provides cancer risk assessment, recommendations regarding medical care and surveillance, and psychosocial support for children and families with a known or suspected hereditary cancer.

Together, a physician and a genetic counselor will see your child and help determine whether they are at risk of developing cancer, and if so, what can be done to prevent cancer or to catch it early. We take into account your child’s unique medical and family history to help you develop a tailored medical plan that may include genetic testing of at-risk individuals. We will help you understand test results and implications for your child and other family members. 

If needed, we will also help coordinate a proper surveillance program for your child, which may include physical exams, labs, imaging, and referrals to other subspecialists. Most importantly, we help to counsel and educate you and your family about living with a diagnosis of hereditary cancer, from diagnostic work-up to long-term follow up.

Prepare for Your Visit

During your visit with the Cancer Genetics team, we will take a thorough family and medical history. We ask that you complete a new patient form prior to your visit with our team.
