Cancer is one of the leading causes of death in
our society. Cancer is a disease in which a cell
in the body loses its sensitivity to factors which
regulate cell growth and division. The cell begins
to multiply without restriction, creating a growing
mass called a tumor, which interferes with the
structure and functioning of the organ in which it
is located.
Frequently, cancer cells become metastatic,
meaning that they travel, settling in a number of
places and giving rise to secondary tumors.
Much of medical research is devoted to finding
ways of preventing, controlling, and curing
cancer.
41. Because of the metastatic trait of cancer
cells, how can
treatment to be effective?
we judge a
cancer
A. if the entire body has been proven free
of tumors over a period of time
B. if the highest possible levels of
treatment have been used
C. if the original-source tumor has been
identified
D. if no new cancer cells are found in 2
weeks
E. if the complete tumor is removed

SCIENCE, TECHNOLOGY, AND SOCIETY The aging process isthought to be initiated at the cellular level. Among the changesthat can occur after a certain number of cell divisions is theloss of a cell’s ability to respond to growth factors and other signals.
