Would your dad qualify for medicare? This would give you options if he does. Also, does he have TRI-Care, he would need to pay c0-pays. There may be times during treatment that you will not be able to wait 2 weeks. When my husband was having radiation and chemo there was some weeks that I would be on the phone with the MD 2-3 times a week and we had weekly visits.I know this is not the care with all.
