Clinical waste products- Samples obtained could include: a. surgical waste tissue samples; b. placenta samples; and c. biopsy samples. These samples will be obtained as a part of standard of care. Procedures involving these sample collections will be done by trained physicians and medical technicians only. The tissue that will be used for research is the tissue that would normally be discarded. After providing informed consent, study participants may allow study personnel to collect these clinical waste products from the clinical sites. The clinical waste product will then be transported to CDRCC on ice for storage. These samples will be de-identified, stored and used for future research. There will be no cost or compensation to the patients for donating this tissue to CDRCC.
