For Patients & Caregivers
If you're experiencing a medical emergency, call 911 immediately.
For nonemergency healthcare needs or to make an appointment, please call 1-800-CEDARS-1 (1-800-233-2771). Representatives are available 24 hours a day.
You can get a second opinion at the Cedars-Sinai Department of Radiation Oncology. You're assured an individualized treatment plan that caters to your physical and emotional needs. In some cases, our physicians may even recommend a multitreatment approach that isn't offered elsewhere. Send us a message to start a conversation.
Same Day Appointments
Whether you're looking for a second opinion or are ready to meet one of our radiation oncologists, we'll work with you to schedule an appointment that is convenient for you. We even offer same-day appointments to make sure you have access to the care you need when you need it.
