I know there’s a reason, but I don’t know what it is.

Cutting out a tumor is something doctors can try to do but in only works in specific circumstances. Many types of tumors can communicate with the body and request blood vessels be built to them and consume resources meant for other organs. In addition, they grow virulently and can grow around critical blood vessels and organs making it essentially impossible to cut out the entire tumor without risking killing the patient. Sometimes the tumors can grow and kill off the cells that form the walls of organs complicating the removal process. If even a single cancerous cell is left behind and not destroyed by the body – it can grow back into another tumor, so it can carry many risks.
Lastly, the most dangerous types of cancer are tumors that actively spread freely throughout the body. Cells can break off and float throughout the body and embed themselves elsewhere growing new masses simultaneously everywhere in the body. At this stage the tumors are likely inoperable – the only way to fight them is chemically or via other means.
