I think a person or designee can have some plans, do some research before treatment start for things under their control, instead of waiting until the need arises, and have it done haphazardly, in panic or not done at all during treatment. I'm talking about looking into their medical benefits, what it covers, costs, duration, continuation, any other insurances, employment benefits, and it's continuation. How you will get to and from treatment, food preparation, shopping, prescriptions, 24hr pharmacy, hours of operation, taking care of animals, children, other responsibilities, and stuff like that.

As mentioned everyone is different. Caution, deferment, personal protection should be used when in public, doing yard work, interacting with any animals, their clean up, especially with a compromised immune system from cancer, and it's treatment. Infections can be dangerous, and progress quickly.

Good luck.
