Now that your PET scan is complete, we have the precise staging data needed to resolve these conflicting recommendations. A PET scan reveals whether the cancer is localized or has spread. If it is localized, fewer chemotherapy cycles (like 3) combined with targeted radiation (28 sessions) may be ideal. If it is more widespread, systemic chemotherapy (up to 6 cycles) is usually prioritized. I highly recommend presenting your PET scan results to a multidisciplinary tumour board or having your medical and radiation oncologists collaborate. This ensures your treatment plan is tailored exactly to your scan findings and specific cancer type.
