1. Which of the following best describes neoplasia?
A) An increase in the size of individual cells
B) The process characterized by abnormal and uncontrolled cell growth and differentiation
C) The replacement of one differentiated cell type with another
D) A decrease in cell size and function
Correct Answer: The process characterized by abnormal and uncontrolled cell growth and differentiation
Rationale: Neoplasia is the process of abnormal, uncontrolled cell growth that deviates from normal
regulatory mechanisms. It involves alterations in genetic pathways governing cellular replication and
differentiation. The result can be benign (non-invasive) or malignant (invasive and capable of
metastasis).
2. What is a neoplasm?
A) The process of abnormal cell growth
B) The actual mass or lesion resulting from abnormal proliferation
C) A type of cellular adaptation to stress
D) A programmed cell death mechanism
Correct Answer: The actual mass or lesion resulting from abnormal proliferation
Rationale: A neoplasm is the resultant mass or lesion of abnormal proliferation, commonly referred to as
a "new growth" or tumor. It represents the physical manifestation of neoplasia and can be benign or
malignant.
3. Proliferation is defined as:
A) The process by which unspecialized cells become specialized
B) The process of cell division leading to an increase in cell number
C) The programmed death of cells
,D) The replacement of one cell type with another
Correct Answer: The process of cell division leading to an increase in cell number
Rationale: Proliferation is the process of cell division that increases cell number, essential for normal
tissue growth and replacement of lost cells. It is a fundamental process that enables tissue renewal and
repair.
4. Differentiation is defined as:
A) The process of cell division leading to an increase in cell number
B) The programmed death of cells
C) The process by which unspecialized cells become specialized in structure and function
D) The abnormal growth of cells
Correct Answer: The process by which unspecialized cells become specialized in structure and function
Rationale: Differentiation is the process by which unspecialized cells become specialized through
changes in gene expression. This ensures cells acquire specific structures and functions necessary for
diverse tissue activities.
5. A benign neoplasm is characterized by:
A) Invasion of adjacent tissues
B) Metastasis to distant sites
C) Localized growth and inability to invade
D) Rapid, uncontrolled growth
Correct Answer: Localized growth and inability to invade
Rationale: Benign neoplasms are non-invasive and localized, meaning they do not invade adjacent
tissues or metastasize. They are typically slow-growing and well-differentiated, unlike malignant
neoplasms which are invasive and capable of metastasis.
, 6. A malignant neoplasm is characterized by:
A) Encapsulated growth
B) Inability to metastasize
C) Invasion of adjacent tissues and metastasis
D) Slow, localized growth
Correct Answer: Invasion of adjacent tissues and metastasis
Rationale: Malignant neoplasms are invasive and capable of metastasis. They can spread to distant sites
via blood or lymph, unlike benign tumors which remain localized and do not invade or metastasize.
7. The spread of cancer cells from the primary tumor to distant sites is called:
A) Proliferation
B) Invasion
C) Metastasis
D) Angiogenesis
Correct Answer: Metastasis
Rationale: Metastasis is the spread of cancer cells from the primary tumor to distant sites via blood or
lymphatic vessels. This is a hallmark of malignant neoplasms and is responsible for the majority of
cancer-related deaths.
8. What is angiogenesis in the context of cancer?
A) The spread of cancer cells to distant sites
B) The formation of new blood vessels to supply a tumor
C) The process of cell division
D) The programmed death of cancer cells
