NUR 426 Final Exam- Lung Cancer
What is the leading cancer killer in men and women in US and worldwide - answer lung
cancer
- more deaths than colorectal, breast, + prostate combined
- 1 out of 4 cancer deaths
What is the long term survival rate of lung cancer - answer very low
- lung cancer spread to lymphatics or metastasized by time of diagnosis in 48.5% of
patients
What is the 5 yr survival rate of lung cancer - answer21.7%
What is the average age at diagnosis for lung cancer - answer71 (65-84)
- mostly a disease of the elderly
What percentage of lung cancers casesb does tobacco and cigarette smoking cause -
answer85-90%
The longer period of smoking causes a higher risk for what - answerlung cancer
risk for lung cancer is determined by what - answerpack-year history
What is pack-year history - answerpacks per day X yrs smoked
- Ex 2 pk per day for 10 yrs = 20 pack yr
the risk of lung cancer decreases with what in regards to tobacco and cigarette smoking
- answernumber of years quit
What is passive smoke or secondhand smoke (SHS) - answersmoke inhaled by people
in close proximity
- inhaled from smoke exhaled
Risk factors and etiology for lung cancer - answer- tobacco and cigarette smoking
- passive smoke or secondhand smoke (SHS)
- Radon
- Other (pesticides, environmental exposures, air pollution, etc)
- cannabis
- vaping
secondhand smoke (SHS) contains what - answermost of the same carcinogens as
firsthand smoke
- at a lower concentration
, passive smoke or secondhand smoke (SHS) can also include smoke from what -
answer- household
- automobile
- buildings
What is radon - answercolorless, odorless inert gas found in soil + rocks
- breakdown product from decaying radium or uranium
- earth metal = very radioactive
Where can radon be found - answer- poorly ventilated basements or underground
dwellings
- underground mines
How does radon enter a home? - answerthough an open space in the foundation, a
crack in the basement floor or foundation the gap around a water or sewer pipe, or a
crawl space allows the radon to enter the home
Other risk factors/etiology of lung cancer include what - answer- pesticides
- environmental exposures (Asbestos)
- air pollution (emissions from motor vehicle/manufacturing plants)
- genetic predisposition
- dietary deficits
- hx of chemo w/ alkylating agents or radiation tx
- COPD/emphysema/TB
What diseases can be risk factors for lung cancer - answer- COPD
- emphysema
- TB
How is cannabis a risk factor for lung cancer - answersimilar carcinogens as tobacco
- 1 "joint" = 20-30 cigarettes
- needs more research
How is vaping a risk factor for lung cancer - answere-cigarette aerosol that users
breathe from the device + exhale can contain harmful + potentially harmful substances
- cancer-causing chemicals
- volatile organic compounds
What are the lung cancer classifications - answer95% grouped into 2 categories
- Non-small cell lung cancer (NSCLC) 84%
- Small cell lung cancer (SCLC) 13%
What are the subtypes of non-small cell lung cancer (NSCLC) - answer-
adenocarcinoma 41%
- squamous cell carcinoma 20%
