Uhhh. How to put this...
While technically you're partially right, the motivation of the bolded part is completely wrong.
Firstly, yes, cancer cells get their energy from glucose, namely blood glucose. What else would they eat? Secondly, eliminating the food source from cancer cells would mean the imminent death of the patient as that would mean removing blood glucose. You can't live without it and you can't get rid of blood glucose via not eating carbs (except if you're diabetic or something).
Saying cancer is affected by carbs in a diet is the equivalent of saying cancer is affected by how much you breathe since oxygen feeds cancer cells (it really does).
Also for an otherwise healthy person, carbs in a balanced diet aren't going to spike blood sugars significantly (ie. not spike them above the completely normal 6 or 7 mmol/l range which you probably get from doing HIIT too. Also as far as I'm aware, spikes in blood glucose won't affect cancer growth.
It's one of those myths again, like meat causing acidity in the body etc.
