Which statement regarding general cancer development is true?
A. The risk for cancer development decreases with age.
B. Cancers usually develop in those tissues that retain their ability to divide.
C. Children born to older mothers have a greater risk for cancer development.
D. Most mutations leading to cancer development occur in structural genes.
B
Cells that are unable to divide, even if they underwent DNA mutation as a result of exposure to a carcinogen, are rarely able to form a tumor (malignant or nonmalignant). The most common cancers (lung, colorectal, prostate, and breast) occur in tissues that retain the ability to divide. The risk for cancer development increases with age. Maternal age is not a risk for cancer devel-opment. Mutations leading to cancer development usually occur in regulatory rather than struc-tural genes.
