In hospitals it is not uncommon to have to choose to save one life, and as a result allow another to die. For example if they only have the resources to save one, they would have to make that terrible decision. The well established ethics based on both compassion and common sense, is to prioritise a young and healthy person before an old or seriously ill one.
A friend of mine (early 30's) had his chemotherapy postponed in March until a couple of weeks from now. If it gets delayed again, I would seriously question the ethics of these restrictions.
This is a serious misreading of the situation. Chemotherapy has a major impact on the immunity system. You have to be able to treat and transport patients to and from home in an infection free bubble. It doesn't matter if the carrier is old and frail or young and healthy, the impact on the cancer patient is the same.
Resources are scarce, but you have to wonder why there are not dedicated cancer treatment centres being set up away from the main hospitals.
