Use this survey if you live outside USA. Please help complete this study. Results will be published.

All members in our group either have a capillary, lymphatic, venous malformation, possibly with arterial involvement, or serve as caretaker for someone with one of these conditions. We are working with The Vascular Anomalies Special Interest Group (SIG), a group of pediatric hematologist-oncologists (blood disorder and cancer specialists) who are interested in learning whether people with KT and related diagnoses are at risk for particular problems. We are hoping you will be willing to answer a few brief questions relating to your/your family member's malformations and other problems which may or may not be related. We are particularly interested in cancer and benign tumor risk. The questions should only take a few minutes to answer. ​This is research, and results hopefully will be published. No publications will include your names or other information which would allow a reader to identify you or any of the participants.
