Hopefully you can help. Do you know if you only get sent for a PET scan after a CT scan if your consultant thinks your cancer has spread? The CT scan shows lung cancer in one lung and lymph nodes are clear but they now want to do a PET scan. I’m scared that they are suspecting something else but not telling us. We’ve had friends at the same hospital who’ve only had a CT scan and then started treatment. If anyone has any thoughts I would be very grateful as I’m sick with worry.
