I’m educated enough to generally understand that cancer is the result of a gene mutation, which activates rapid cell reproduction, but what about this growing/spreading tumor makes it fatal? Why can’t we just periodically remove the tumor as it continues grow, thereby (almost) completely eliminating any possible death threat from cancer?
***EDIT: thanks for all the responses to my question! Some of them are really great, and perfectly answer my question. Frankly, I was not aware that cancerous cells and tumors have, in so many ways, “a mind of their own”.***
***I’m very lucky to have been of general good health my whole life, but the threat of cancer as I age scares the daylights outta me — it literally keeps me up at night, often. I’m slightly relieved to realize that so much is known about cancer and so many different treatment options exist, depending on the diagnosis and prognosis. And I recognize this wealth of knowledge, understanding, and treatment options is growing almost by the day with modern medicine — and this helps put me at ease a little too.***

Removing some tumors, like neuroendocrine tumors, can make things worse. Cancer tissue starts replacing healthy tissue, and soon enough you don’t have enough healthy tissue left. Not only that, lots of solid tumors create blood supply to themselves so they start stealing nutrients and removing them gets much, much harder.
That said, there are more and more treatments that are making cancer survivable.
