Question 1

What is the most important risk factor for lung cancer?&#10;A) obesity&#10;B) air pollution&#10;C) smoking&#10;D) family history of cancer

Accepted Answer

Smoking is the most significant risk factor for lung cancer, responsible for the majority of cases.

Question 2

In the United States, lung cancer incidence ranks second to _____ cancer among women.&#10;A) pancreatic&#10;B) thyroid&#10;C) cervical&#10;D) breast

Accepted Answer

Breast cancer is the most common cancer among women in the United States, making lung cancer the second most common.

Question 3

What breast cancer treatment has been associated with an increased risk of lung cancer?&#10;A) radiotherapy&#10;B) chemotherapy&#10;C) mastectomy/lumpectomy&#10;D) biological therapy drugs

Accepted Answer

Radiotherapy for breast cancer can increase the risk of developing lung cancer, particularly if the radiation is directed towards the chest area.

Question 4

What is currently considered the best option for lung cancer patients?&#10;A) chemotherapy&#10;B) radiation&#10;C) surgery&#10;D) biological therapy

Accepted Answer

Surgery is often considered the best option for lung cancer patients, especially if the cancer is detected early and is localized, as it can potentially remove the tumor completely.

Question 5

Which of the following is associated with an increased risk of lung cancer for never smokers?&#10;A) chlorine&#10;B) radon&#10;C) lead&#10;D) peroxide

Accepted Answer

Radon is a naturally occurring radioactive gas that can accumulate in homes and buildings, and it is a known risk factor for lung cancer, even in never smokers.

Question 6

Which virus has been suggested to be an important risk factor for lung cancer?&#10;A) HIV&#10;B) HPV&#10;C) HBV&#10;D) HCV

Accepted Answer

Human Papillomavirus (HPV) has been suggested in some studies to be a potential risk factor for lung cancer, although it is more commonly associated with cervical and other anogenital cancers.

Question 7

Results from randomized trials indicate that supplemental _____ at high doses increases lung cancer risk among current smokers.&#10;A) riboflavin&#10;B) beta-carotene&#10;C) folate&#10;D) echinacea

Accepted Answer

Studies have shown that high doses of beta-carotene supplements can increase the risk of lung cancer in current smokers.

Question 8

A family history of lung cancer is not considered a significant risk factor for lung cancer.

Accepted Answer

Family history is considered a significant risk factor for lung cancer, as genetic predispositions can increase the likelihood of developing the disease.

Question 9

Involuntary exposure to smoking is carcinogenic to humans.

Accepted Answer

Involuntary exposure to smoking, also known as secondhand smoke, contains carcinogens that can cause cancer in humans.

Question 10

Men are more likely to undergo surgery for early-stage lung cancer than women.

Accepted Answer

Studies have shown that women are more likely to undergo surgery for early-stage lung cancer compared to men, possibly due to differences in health-seeking behavior and physician recommendations.
