Which medical term describes s cancer that is easier to treat and has a better prognosis for recovery because it has not spread to surrounding tissue?

The medical term that describes a cancer that is easier to treat and has a better prognosis because it has not spread to surrounding tissue is "localized cancer." Localized cancers are confined to their original site and have not metastasized, making them generally more amenable to treatments such as surgery, radiation, or targeted therapies, leading to improved chances of recovery.
