I don't think you should ask how many lives will be lost? You should ask how many have beensince the discovery of this drug. And this video is obviously very old.
I have 3 friends, 2 studying to be doctors and 1 done with medical school and practicing. Working long hours, and helping and having an effect on lives.
They've educated me,and brought to my understanding that they are many different cancers and it is not just that it is 1 disease as many people perceive it to be.
Yes they are many different cancers so this drug 'might' not have a great affect on all but it possible would help destroy some.
Looking into vitamin b-17 and see what more you can find from that.
