●● Define Neoplasm
Answer: means the new growth itself
●● Define Proliferation
Answer: process of cell division where new cell growth replaces old
cells or when additional cells are needed
●● Define Differentiation
Answer: the process by which cells become more specialized with each
mitotice division
●● Describe the cell cycle
Answer: G1 to S phase to G2 to M phase
●● What are the 3 main groups of cells that proliferate?
Answer: 1. well differentiated neurons and cells of skeletal and cardiac
muscles that rarely divide and reproduce
, 2. progenitor or parent cells that continue to divide and reproduce, such
as blood, skin, and liver cells
3. undifferentiated stem cells that can enter the cell cycle and produce
large numbers of progenitor cells if needed
●● What are progenitor cells?
Answer: biological cell that has a tendency to differentiate into a specific
type of cell, but is already more specific than a stem cell and is pushed
to differentiate into its "target" cell
●● What are the benefits of the stem cell?
Answer: self-renewal and potency meaning they can undergo numerous
mitotic divisions while maintaining an undifferentiated state and they
vary in differentiation potential
●● What is the difference between malignant and benign tumors?
Answer: Malignant tumors invade and destory tissue, growing rapidly
and spreading to other parts of the body
Benign tumors grow by expansion and remain localized to their site of
origin, not capable of metastising
●● What is polyp?
Answer: growth that projects from a mucosal surface (like the intestine);
malignant or benign
