Stage III cancer is described as which of the following?

Stage III cancer is described as which of the following?

• A. Stage I: Localised, small tumour, no nodal/distant spread.
• B. Stage IV: Distant metastasis present.
• C. Stage III: Extensive nodal involvement or locally advanced tumour.
• D. Stage II: Larger tumour and/or limited nodal involvement, no distant metastasis.

Answer: (C)

Stage III describes cancers with extensive regional spread, either through many nearby lymph nodes or a locally advanced tumor that has grown into surrounding tissues, but without distant metastasis. This level of spread shows more extensive local involvement but has not yet reached distant organs, which is what separates Stage III from Stage II (smaller or less nodal involvement with no distant spread) and Stage IV (distant metastasis). In practical terms, you might see a cancer with multiple affected regional lymph nodes or a tumor large enough to invade nearby structures, yet imaging or exams do not show metastasis to distant sites. The other descriptions fit different stages: a small, localized tumor with no nodal/distant spread is stage I; a larger tumor with some but not extensive nodal involvement and no distant spread is stage II; distant metastasis defines stage IV.
