1.The stage of carcinogenesis in which the deoxyribonucleic acid (DNA) of the cell undergoes mutation is
called
a. initiation.
b. metastasis.
c. promotion.
d. progression.
ANS: A
The DNA of the cell undergoes mutation in the initiation stage of carcinogenesis. Promotion is the
second stage in which abnormal cell growth occurs. Progression is the third stage in which cancer
cells spread beyond their original location. Metastasis is formation of cancer in secondary sites.

2. Dietary factors that may help protect against carcinogenesis include
a. electrolytes.
b. amino acids.
c. antioxidants.
d. monounsaturated fatty acids.
ANS: C
Dietary antioxidants, found in fruits and vegetables as well as some other foods, may help protect
against carcinogenesis. Electrolytes, amino acids, and monounsaturated fatty acids are all important
in maintaining good nutritional status but do not help protect against carcinogenesis.

3. Fruits and vegetables contain some specific chemicals that help prevent cancer, known as
a. phytosterols.
b. vitamins.
c. antineoplastics.
d. phytochemicals.
ANS: D
Fruits and vegetables contain phytochemicals that help prevent cancer. They have antineoplastic
qualities, but this is not what they are called. Fruits and vegetables contain vitamins, but not all
vitamins help prevent cancer. Phytosterols are found in plant oils and help lower blood cholesterol
, level.

4. A dietary change that would help prevent cancer, according to the National Cancer Institute
recommendations, is
a. eating vegetarian meals two or more times a week.
b. choosing organic, pesticide-free fruits and vegetables.
c. eating five or more daily servings of fruits and vegetables.
d. consuming three or more daily servings of low-fat dairy products.
ANS: C
Eating five of more daily servings of fruits and vegetables would help prevent cancer. Eating
vegetarian meals two or more times a week may help prevent cardiovascular disease. Choosing
organic, pesticide-free fruits and vegetables would help protect the environment. Consuming three or
more daily servings of low-fat dairy products would help prevent osteoporosis and hypertension.

5. The syndrome of loss of lean body mass and body fat stores that occurs in many patients with cancer
is called
a. cachexia.
b. anorexia.
c. neoplasia.
d. catabolism.
ANS: A
The syndrome of loss of lean body mass and body fat stores that occurs in many patients with cancer
is called cachexia. Anorexia refers to loss of appetite or restriction of food intake without the
metabolic effects that cause excessive wasting; anorexia may contribute to cachexia in patients with
cancer. Neoplasia refers to the abnormal proliferation of cells seen in cancer. Catabolism refers to the
breakdown of lean tissue and fat leads to wasting.

6. Benefits of adequate dietary intake in patients with cancer include
a. decreased risk of hypertension.
b. increased tolerance of therapy.
c. prevention of metastasis of the disease.
