Hi,
In Oct 2023, My dad's MRI revealed that cancer had spread to few vertebral bones and has reached a rib bone. He got a PET scan and then underwent ~20 days of radiotherapy in Nov 2023.
But his doctor has not asked him to do any follow-up tests after the radiotherapy ended. Is this the norm? Should he be doing additional tests to determine if the radiotherapy had it's intended effects and if additional therapy is needed? I am very worried that the cancer had reached his rib bone. I want to be proactive in monitoring this and prevent further spread.
I have provided additional information on his history in the comments below.
