The immunological drugs really are game changers. Up until now we have had three basic ways of treating cancer: cut, irradiate or poison. These basically never work on advanced cancers, or cancers that come back after initial treatment.

The immunological drugs turn the immune system against the cancer and this approach can cure cancers that are untreatable using other methods. It is still really early days, but the immunological drugs are able to take patients that are weeks from death, and for which everything else has failed, and cure them.

What we really need to know if why it does not work for everyone, but it provides a crack into which we can hammer a wedge.
