D) CIS.

Question

Quizplus · Accepted Answer

The spread of cancer to distant sites is called metastasis. Direct extension of cancer beyond its site of origin is also possible, but the term metastasis specifically refers to the spread of cancer to distant sites through the bloodstream or lymphatic system. Apoptosis is programmed cell death, which can be disrupted in cancer cells. Dedifferentiation refers to cancer cells losing their specialized characteristics and becoming more primitive. CIS (carcinoma in situ) is a type of cancer that remains confined to its site of origin and has not spread to nearby tissues.
