This study aims to discover new genes that may cause certain cancers to run in families. Researchers will collect blood samples and health information from 1,500 people in families where multiple members have had cancer, especially childhood cancers. The goal is to build a regist…

This study follows 50 children with PTEN gene mutations to better understand their risk of developing tumors. Participants will have yearly check-ups including blood tests, ultrasounds, and skin exams for 5 years. The goal is to create better monitoring guidelines for these child…

This study follows 4700 women with high-risk gene mutations (like BRCA1/2) who choose to have a nipple-sparing mastectomy to prevent breast cancer. Researchers want to see if keeping the nipple is safe over many years, compared to traditional mastectomy that removes it. The goal …

This study is creating a registry for children with PTEN Hamartoma Tumor Syndrome (PHTS), a rare genetic condition that increases cancer risk. Researchers will follow 100 participants for 3 years to link genetic changes with health outcomes. The goal is to develop better monitori…

This study aims to create a large collection of blood samples from 2,500 people with or at high risk for cancer. Researchers will use these samples to study liquid biopsies, which are blood tests that may help detect cancer, track treatment response, and spot recurrence. Particip…
