What term describes the mechanism by which disease develops?

Accepted Answer

Pathogenesis — Pathogenesis refers to the mechanism or sequence of events by which a disease develops, including the molecular and cellular changes that occur.

Question 23

What is a malignant neoplasm of fat tissue called?

Accepted Answer

Liposarcoma — A malignant neoplasm of fat (adipose) tissue is called a liposarcoma. The benign counterpart is a lipoma.

Question 24

What type of carcinoma arises from squamous epithelium?

Accepted Answer

Squamous cell carcinoma — Squamous cell carcinoma arises from squamous epithelium and is a malignant neoplasm of epithelial origin, commonly found in skin, lung, and other organs.

Question 37

What is the primary reason for studying investigations in neoplasia?

Accepted Answer

For accurate diagnosis and staging — Studying investigations (laboratory tests, imaging, biopsies) is crucial for accurate diagnosis, staging, and determining appropriate treatment strategies for neoplasms.
