Read our Prostate Cancer research guide →This is a research study where scientists collect blood, tissue, urine, saliva, and stool samples from people diagnosed with cancer (such as prostate, breast, colon, lung, or liver cancer) and from healthy volunteers. These samples help researchers study how cancer develops, identify early warning signs, and understand why some people experience side effects from cancer treatments.
Cancer research relies on studying real samples from patients to discover new ways to detect cancer earlier, predict which treatments will work best, and develop safer, more effective therapies. This trial exists to build a large collection of samples that researchers can use to unlock new insights into cancer biology and improve care for future patients.

You will visit an NIH clinical center for an initial appointment where doctors will review your health information and collect samples such as blood, and possibly tissue, urine, or saliva. You may be asked to return for follow-up visits if researchers need additional samples. The study involves no experimental medications or invasive procedures — it is purely about donating samples for laboratory analysis.
