The organs are the functional units of the body. Each organ has its own job: The heart pumps the blood, the kidneys are filtering it, the brain is controlling the body, the stomach digests food….. To name a few. Does that answer your question?
Different type of organs do different functions like Susanne said. And you cannot replace one for the other. Sometimes they come in pairs, like your kidneys and your lungs. In this case, for instance, if one kidney doesn’t work properly, the other one tries to work harder to compensate. Did you know that the biggest organ of your body is your skin? And that the liver is the only internal organ that, if you remove part of it, it can regenerate?
The seriousness of a cancer depends on which organ it came from originally. Cancers from the skin, for example, are mostly not that dangerous (unless they’re melanoma, which is from the pigment cells, which is nasty). Tumours from pancreas cells or lung cells can be really brutal, though, and it’s hard to survive cancer from those cells.
