If given adequate blood/nutrition/space, would a cancer continue growing indefinitely?

I understand that cancer cells are immortal (i.e. do not undergo apoptosis). So if a cancer was grown in vitro, would the cancer just...keep growing?

They can do, yes - the best example of this is the HeLa cell line, which was cervical cancer cells taken from a woman called Henrietta Lacks way back in 1951 (there's a fascinating backstory about these if you're interested to look them up). Anyway, that cell line has been proliferating since then, and has been used in huge numbers of medical breakthroughs in the last 60 years, including the polio vaccine, AIDS research and cloning experiments.
