How does cancer cause?

Answer 1

by ur body

If you're talking cell-wise;

if your body accidently produces a 'faulty cell' it normally kills itself.

But if you have cancerous cells these fail at this and carry on multiplying on the wound making a lump appear. This is cancer.

Answer 2

I'm not sure I understand the question. But cancer can cause multiple symptoms. Such as, tiredness, aches, muscle pains, and stunted growth in some areas.
