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

Surgically cutting out cancer is routinely done. This is more common and effective for certain types of cancers, may not work for all cancer, but your question of “why can it not be done” is not true.
Common examples include surgically removing the breasts to remove breast cancer, or cutting out a section of the colon/intestines for colon cancer.
Once the cancer has metastasized throughout your body, leading to numerous tumours everywhere all over the body, then surgical removing of so many tumours becomes impossible.
Certain types of cancer may also carry high risk of side effects for surgery – such as having to remove a large section of a vital organ, or located in an area that’s difficult to access. So surgery is less desirable in these types of cancers and other treatments will be better.
