Which of the following lists the primary SEER Summary Stage 2000 (SS2000) categories?

The main idea is understanding the four SS2000 categories that describe how far cancer has spread at diagnosis. SEER Summary Stage 2000 uses four primary categories: in situ, localized, regional, and distant. In situ means the cancer is non-invasive and confined to the site of origin. Localized means the cancer is limited to the organ or site of origin. Regional indicates spread to nearby structures or regional lymph nodes. Distant denotes metastasis to distant organs or sites. The best answer lists these four categories in the standard order: In situ, Localized, Regional, Distant. The other options include terms not used in SS2000 (like Extended or Unknown) or arrange the categories in a nonstandard order, so they don’t reflect the official SS2000 categorization.
