What taking part in a solid tumor cancer study involves

A screening visit first

Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.

Care at a nearby site

Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.

You stay in control

Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.

The team decides eligibility

Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
