I've not read the article, but I understand from the comments this is about glioblastoma.

I understand that these cancers requires carbs to grow, and going into ketosis - which is to say, fully depleting the body of carbs and having none in your diet - is a highly effective coping mechanism. The cancer basically stops growing. Of course, you then have to live on protein and fat, but better that, than death.
