 Treatments with expensive medicines start right away and they also come with a string of non-medical costs like lodging, travel. A lot of patients travel far for care, parking at the hospitals. And then chemotherapy and other treatments often leave patients too weak to work. And that can result in patients losing their income and their health insurance. And so if you sort of get off on the wrong foot like that, your situation can sort of really spiral. Mm-hmm.
