This research study asks patients diagnosed with early stomach cancer or precancerous stomach growths to donate tissue samples (from their existing biopsy or removal procedure) and blood for genetic testing. The researchers will analyze the genetic makeup of the cancer cells to identify specific mutations and abnormalities that might guide personalized treatment recommendations in the future.
Different stomach cancers have different genetic profiles, and understanding these differences could help doctors choose treatments that work best for each individual patient rather than using a one-size-fits-all approach.

You would donate leftover tissue from your previous biopsy or removal procedure and provide a blood sample (about 10 milliliters, roughly two teaspoons). The researchers will perform genetic testing on these samples. Additional tissue and blood samples may be collected at 2 months after treatment, 1 year after treatment, and if cancer recurs, to track how your cancer's genetics change over time.
