Would a uterine cancer clinical trial (research study) be appropriate for me?

Cancer of the. Uterus usually means "body and endometrium" not cervix, catalogued and trials designed separately. However, your age (22) and location (near stanford) means uterus is unlikely and you have a major nci funded cancer center on your door step. Dial 1-800-4 cancer. Trials are not for everyone, but learning what is available can be valuable.
Depends. Can't answer that question without details. Talk with your oncologist or treating gynecologist.
