All (human) cells feed on glucose (or fatty acids or amino acids, depending on what's available). For thia to work, they need oxygen (although there are ways to gain energy without oxygen too). That's true for cancer and normal cells.

Additionally, not every cancer works the same way. Different mutations cause different cancers. That's why it's nearly impossible to find one single cure. And no, cancer cells are not "completely different" than normal cells. They're usually just don't die as easily and multiply a lot.

Change in the alteration of their genetic sequence is different for different cancers. I admit. But they multiply at a uncontrolled rate of growth which is ovbiously different from 'normal cells'

Different, but not "completely different" as you stated above. In fact, many mutations are just a single switched base. Not much of a difference and not enough to change its whole metabolism.

Oh okay! But I didnot stressed too much on 'completely'. Just added my view. May be I should have to care on my every words now!

Since I am a student and a learner here so Forgive me :)

Dude.
What?!?

Words mean things. By using words like Facts and Completely you are drawing a conversational line in the sand.

Just own up and say that they're your Beliefs . It won't automatically make them right, but it will be accurate.

Try to be calm and after when I have done with that no need of one more point. And what are you talking about . Did you even read my post seriously! If i am wrong just put your point corrrctly. To prove someone wrong you need to put your RIGHT point.

I'm not trying to prove you wrong.

I'm telling you that if you're arguing a scientific point that you need to choose your words for accuracy.

FYI, the scientific method isn't a way to find the right answers, it's a way to filter out the wrong answers. So no, they don't need to provide the right answer to you, they just need to show where your wrong answer fails.
