Mass Response of Tumor Cells as a Biomarker for Rapid Therapy Guidance (TraveraRTGx)

This study is testing a lab method that measures the physical weight change of individual cancer cells to quickly predict whether a patient's cancer will respond to a given treatment. The goal is to help doctors choose the best therapy faster, using cells collected from fluid or tissue during standard clinical procedures. **You may be eligible if...** - You are 18 or older with any type of carcinoma - You are already scheduled to have fluid drained (e.g., from the chest or abdomen) or a tumor biopsy as part of your regular care - You are willing to have some of that sample used for research testing **You may NOT be eligible if...** - You are not already having a clinically necessary procedure to obtain a sample - You are unable to provide informed consent Talk to your doctor to see if this trial is right for you.
