Outside the cell: When the changes of carcinoma in situ extend outside the bottom cells which are lined up in levels, it "invades" other parts of the tissue, therefore becoming invasive, ergo cancer.

A cancer develops in: An organ (lung, breast, ovary). Metastasis is the travelling of the cancer from that organ to another, establishing a colony there, growing, and interfering with taht organs function.

Spread outside area: Metastatic carcinoma refers to the spread of the cancer outside the area of origin. For some cancers, this can be spread to nodes outside the area that drains the organ involved (esophageal) or it can refer to multiple tumors within the same organ (liver - cholangiocarcinoma).
