MULTIPLE CHOICE

 

1. Which characteristic among women correlates with a high morbidity of cancer of the colon, uterus, and kidney?

a.	Women older than 45 years of age
b.	Women who have never had children
c.	Women who have a high body mass index D. Woman who have smoked for more than 10 years

 

 

ANS:  C

A recent hypothesis states that the observed increased incidence of such cancers as breast, endometrium, colon, liver, kidney, and adenomas of the esophagus may be associated with obesity. No current research supports the remaining options.

2. Which substance has been shown to increase the risk of cancer when used in combination with tobacco smoking?

a.	Alcohol	c.	Antihistamines
b.	Steroids	d.	Antidepressants

 

 

ANS:  A

Alcohol interacts with smoke, increasing the risk of malignant tumors, possibly by acting as a solvent for the carcinogenic chemicals in smoke products. No current research supports the remaining options as having an increased effect on the incidence of cancer when used in combination with tobacco smoking.

3. Which cancers pose the highest risk for radiologists?

a.	Thyroid	c.	Leukemia

4. Research has shown a link between cancer and which sexually transmitted disease?

a.	Syphilis	c.	Human papillomavirus
b.	Gonorrhea	d.	Pelvic inflammatory disease

 

 

ANS:  C

Human papillomavirus (HPV) is the most common sexually transmitted virus in the United States. High-risk, or oncogenic, HPVs can cause cancer. A persistence of infection with high-risk HPV is a prerequisite for the development of cervical intraepithelial neoplasia (CIN) lesions and invasive cervical cancers. No research supports such a link between the remaining options and cancer.

5. Research has supported that alcohol consumption has a convincing impact on increasing the risk of which cancer?

a.	Lung	c.	Pharynx
b.	Breast	d.	Pancreas

 

 

ANS:  C

Research had shown that alcohol consumption has a convincing positive impact on the risk of developing pharynx cancer. No research supports such a connection with the remaining options.
