Cancer is a destructive disease. Describe its impact on the body.
Answer:
Because cancer cells are abnormal cells, they do not function properly in their
tissues of origin, so they do not support body functions. Further, because cancer cells lack
contact inhibition and do not die, they eventually begin to crowd out healthy cells. Finally,
cancer cells spread to other sites in the body, multiplying the problem.

Why is lung cancer the leading cause of cancer deaths?
Answer:
The main reason lung cancer kills so many is that smoking is a popular habit, and
smoking often leads to lung cancer because of the manner in which tobacco smoke invades the
lungs with toxins. The nature of lung cancer is such that it usually cannot be diagnosed until it is
in an advanced stage; therefore, survival rates are very poor.

Explain the importance of the Pap test.
Answer:
The Pap test is an early detection method for cervical cancer that can identify
precancerous changes in tissues before they actually become cancers. It is an effective and easily
administered test. When used with regular screening, the vast majority of cervical cancer cases
can be not only identified but prevented.

Explain how lifestyle changes can reduce your cancer risk.
Answer:
Quitting or avoiding smoking can reduce most of the risk for lung cancer and
other smoking-related cancers of the mouth and respiratory tract. Avoiding carcinogens in the
environment, especially in the workplace, is also an important prevention measure. A healthy
diet and weight control can also have a preventative effect, as can regular exercise. Limiting
exposure to the sun will slow the development of skin cancer. Avoiding heavy use of alcohol can
also lower the risk of some cancers. Know your family history for cancer, and be aware that early
screening for certain cancers may be appropriate in this situation.

Describe the similarities and differences between type 1 and type 2 diabetes mellitus.
Answer:
Similarities: Both occur because insulin is unable to facilitate the transport of glucose into body
cells; both result in excess blood glucose; the symptoms and long-term damage are generally the
same.
Differences: Type 2 diabetes features normal insulin production, while type 1 is marked by the
absence of insulin production. Type 1 diabetes always requires regular doses of insulin from an
outside source.
