All new biopsy positive patients that have a treatment plan or receive surgery, chemotherapy or radiation therapy at Stanford in any of the following cancer care programs (CCP) will be eligible for a navigator: breast, gynecologic oncology, head/neck, gastrointestinal, cutaneous (melanoma patients only), and thoracic. Because there will be more patients eligible than the navigators can manage, only patients with an even MRN will receive a navigator for the pilot. The overall purpose of the pilot is to learn which patients benefit most and which services navigators are able to best help with. The investigators expect the pilot to last 6-12 months. Mixed methods will be used to evaluate the navigators and will include existing patient surveys,missed appointments, unscheduled hospitalizations, ER visits, phone call center volume, time to treatment, increase of percentage of new patients receiving treatment at Stanford, interviews with patients, staff (including navigators), and physicians regarding their experience with and perceived value of navigators
