I am 68 years old and need a primary care doctor. Is an internal dr a good choice ? I m needing to check my AC1 for diabetes...also thyroid....haven t had a doctor in MANY years. Had a lumpectomy Nov 2013 w radiation and have been taking estrogen blocker. All is well with oncologist. Now have lab work twice year, surgeon once a year. Just know I have a lot to have checked and finding the right primary care is hard for me.
