Cancer Genetics Counseling Services

Many cancers have been linked to specific genetic mutations.  These “mistakes” in the genetic code or instruction manual can lead to abnormal growth and function of otherwise normal cells.  Some mutations may also, in turn, be passed on within the family as inherited risk factors for cancer.

Cancer genetics counseling services are conducted at both the Cancer therapy and Research Center (CTRC) and CHRISTUS Santa Rosa Children’s Hospital providing comprehensive and compassionate state-of-the art clinical care to patients and families at high risk for cancer and provide expert clinical evaluations to patients referred to the University of Texas Health Science Center at San Antonio (UTHSCSA) and its affiliated health programs.

Our goals include providing family centered patient care that encompasses diagnosis and effective interventions of genetic disorders related to malignancy and give information promoting healthcare.  It is our hope that families and referring physicians will appreciate the scope of various cancer related genetic disorders.
