What are the benefits of the stem cell?
Stem cells remain dormant until they are needed. When needed, they can divide, produce
other stem cells, and carry out the functions of the differentiated cell. Two important
properties that stem cells possess are self-renewal and potency. Self-renewal means the stem
cell can undergo numerous mitotic divisions while maintaining an undifferentiated state.
Potency describes the differentiation potential of stem cells.
What is a polyp?
A polyp is a growth that projects from a mucosal surface, such as the intestine. A polyp can be
benign or malignant.
Compare and contrast benign and malignant tumors:
Explain metastasis and how it occurs:
The multi-step process of metastasis occurs as follows: a cancer cell must break loose from the
primary tumor, invade the surrounding extracellular matrix, gain access to a blood vessel,
survive its passage in the bloodstream, emerge at a favorable location, invade the surrounding
tissue, begin to grow, and establish a blood supply.
What are the two broad categories of malignant neoplasms?
Solid tumors and hematologic cancers
Explain what carcinoma in situ is?
Carcinoma in situ is a localized preinvasive lesion. These can typically be surgically removed or
treated, and recurrence is less likely.
