Second Opinions

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.

For a consultation appointment or a second opinion, email us at groupradoncconsult@cshs.org.


Same-Day Appointments

We're available to schedule same-day and future appointments. Same-day appointments enable us to provide you care when unplanned conditions occur. We want you to be able to get the care you need right away.

Appointments may be scheduled with one of our radiation oncologists Monday through Friday from 8 a.m.-5 p.m
