In many cases,in the US, the rack rate for a full course of a serious cancer is easily the $500k I suggested and frequently more than double that. My treatment for a suspected single point melanoma was close to $75,000 and it was a single outpatient procedure with a pre- and post-op office follow up. No chemo, no stage designation, nothing - zero cancer found at the site of the questionable biopsy site.

It’s true the Luxturna is an odd case (though the OP article is talking about customized treatment so it is appropriate here). It’s not the disease or cure but the justification of how they determined the cost of their treatment. Not based on the research cost or market, not based on the production or application of the treatment, but on the value of your eyesight they would be preserving.
