Question

An invasive but not metastatic tumor is one in which____

A. The cancer cels have dedifferentiated but have not traveled through the bloodstream
B. The cancer cells have induced angiogenesis but have not traveled through the bloodstream
C. The cancer cells have migrated into tissues surrounding the primary tumor but have not traveled through the bloodstream
D. None of the above

Answer 1

An invasive but not metastatic tumor refers to cancer that has spread to nearby tissues without traveling through the bloodstream to distant sites, specifically described by option C.

Step-by-step explanation:

An invasive but not metastatic tumor refers to the scenario where cancer cells have indeed spread into and invaded the tissues surrounding the primary tumor without traveling through the bloodstream to remote sites. Among the choices provided, the most appropriate answer is C. The cancer cells have migrated into tissues surrounding the primary tumor but have not traveled through the bloodstream. This definition aligns with the understanding that while the tumor is invasive, it has not led to the formation of new, distant tumors, known as metastases.
