Mesothelioma Navy Asbestos-Related Diseases & Health Effects 3

Question 1

What is the synergistic relationship between cigarette smoking and asbestos exposure?

Accepted Answer

Smoking and asbestos together dramatically increase lung cancer risk beyond what either causes alone

Answer

Smoking reduces the risk of mesothelioma in asbestos-exposed workers

Answer

Smoking has no measurable effect on asbestos-related disease outcomes

Answer

Asbestos exposure alone is far more dangerous than the combination with smoking

Question 2

Pericardial mesothelioma affects which structure?

Accepted Answer

The pericardium, the sac surrounding the heart

Answer

The peritoneum lining the abdominal cavity

Answer

The pleura lining the lungs

Answer

The tunica vaginalis lining the scrotal sac

Question 3

What is rounded atelectasis (Blesovsky syndrome) in the context of asbestos exposure?

Accepted Answer

A benign lung lesion appearing as a rounded mass associated with pleural disease

Answer

A malignant lung tumor unique to asbestos-exposed workers

Answer

Collapse of a full lung lobe due to pleural effusion

Answer

Calcification of pre-existing pleural plaques

Question 4

Which histological (cell) type of pleural mesothelioma is the most common?

Accepted Answer

Epithelioid

Answer

Sarcomatoid

Answer

Biphasic (mixed)

Answer

Desmoplastic

Question 5

Which biomarker is most commonly used to help diagnose malignant mesothelioma?

Accepted Answer

Soluble mesothelin-related peptides (SMRP/mesothelin)

Answer

Prostate-specific antigen (PSA)

Answer

Carcinoembryonic antigen (CEA)

Answer

Alpha-fetoprotein (AFP)

Question 6

What structural difference between serpentine (chrysotile) and amphibole asbestos fibers affects their carcinogenic potential?

Accepted Answer

Amphibole fibers have a straight, needle-like structure that persists longer in lung tissue

Answer

Serpentine fibers are more rigid and penetrate deeper into lung tissue

Answer

Chrysotile fibers are more carcinogenic due to higher iron content

Answer

There is no clinically significant structural difference between the two fiber types

Question 7

Secondary or 'take-home' asbestos exposure refers to what type of exposure?

Accepted Answer

Exposure of family members via contaminated clothing or materials brought home by workers

Answer

Exposure from using asbestos-containing consumer household products

Answer

Exposure from living near an active asbestos mining or manufacturing facility

Answer

A second round of occupational exposure after initially being treated for asbestos disease
