Going back to the original question, does anyone know of any others?
There has been enormous progress in the treatment of most cancer types in the past 20 years. Survival from and complete eradication of a person's cancer disease is common. Incurable HIV has been cured in some cases.
Meanwhile, there have been no effective commercial treatments developed and available for chronic SCI. Ever.
Don't orders of magnitude more people die from cancer, in the US, every single year (8-10,000,000) than are living today with SCI from every year combined (250-300,000)?! I think it's less a matter of awareness and more one of proportionality. Finite public resources command Utilitarian decisions.
