Shelley:
Each individual Doctor, is just that, an individual. Some require monthly visits, some every two months and some every three months. This is common for at least the first year. As far as being gentle, that again is individualism. My ENT does not know the definition of gentle. He just calls his finger exams, "rude and crude".
As for CT scans, I have had two so far..., Shelley, you'll have to let us know what kind of oral cancer Ron had and if their were any lymph nodes involved, etc, etc..
