Colon cancer '09 & hepatic resection 2 yrs ago. no chemo for 5 yrs. what type doc should i see for 6 mo. follow ups? internist? primary care? onc?

Internist: You can see internist, they follow-up on your liver enzymes and colonoscopies. If they see anything serious , they will refer you as needed to hemoncologist or gastroenterologist.

Oncologist /surgeon: You are now 5 years since your colon cancer but only 2 years since your liver resection which i presume was done for at least one metastasis(spread). You still have significant risk of especially liver recurrence and should be followed at least every 3 to 6 months with a CEA blood test at each visit to find a recurrence as early as possible. Any of your docs is fine for follow up.
