Answer to Question 1
Correct Answer: 2
Rationale 1: Cancer is abnormal, uncontrolled cell division.
Rationale 2: Cancer is characterized by abnormal, uncontrolled cell division.
Rationale 3: Cancer is abnormal cell division.
Rationale 4: Cancer is uncontrolled cell division.
Global Rationale: Cancer is characterized by rapid, uncontrolled growth of cells that eventually invade normal tissues and metastasize. This growth is abnormal.
Answer to Question 2
Correct Answer: 3
Rationale 1: Grading is a process that examines potential cancer cells under a microscope and compares their appearance with normal parent cells.
Rationale 2: Carcinogenesis, or oncogenesis, is the process by which normal cells are transformed into cancer cells.
Rationale 3: Metastasis occurs when cancerous cells travel to distant sites and populate new tumors.
Rationale 4: Angiogenesis is the process of forming new blood vessels.
Global Rationale: Unlike most normal cells, cancerous cells are able to move to other places in the body. The abnormal cells often travel to distant sites where they populate new tumors, a process called metastasis. Grading is a process that examines potential cancer cells under a microscope and compares their appearance with normal parent cells. Carcinogenesis, or oncogenesis, is the process by which normal cells are transformed into cancer cells. Angiogenesis is the process of forming new blood vessels.
