lung cancer Flashcards
what are the 2 main types of cancer
Small cell lung carcinoma (SCLC)
–>worst to have
Non-small cell carcinoma (NSCLC)
What is includedin SCLC?
Small cell carcinoma (oat cell cancer)
combined small cell carcinoma
OR mixed small cell & non-small cell carcioma
what is included in NON-SCLC
squamous cell
adenocarcinoma
large cell carcinoma
def of cancer
abnormal new tissue growth characterized by the progressive, uncontrolled multiplication of cells
what does abnormal growth of new cells called
neoplasm or tumor
how is tumor classified
localized or invasive,
benign or malignant.
what is benign tumors
do not endanger life unless they interfere with the normal functions of other organs or affect a vital organ
what is malignant tumor

what is metastsis
when malignant tumor invade its surrounding
what does malignant origin in the lung

aka bronchogenic carcinoma
what is the most common cause of lung cancer
cigarette smoking
can secondhand smoke cause cancer
Passive, or secondhand, smoking is associated with as much as a 30% increase in the risk of cancer
what is the pathophysiology of lung cancer
exposure to cacinogen damage genetic material of lung cell
+
genetic predisposition
which cancer has the strongest correlation with smoking
Small-cell lung cancer
what are the Anatomic Alterations of the Lungs
Inflammation, swelling, and destruction of the bronchial airways and alveoli •Excessive mucus production •Tracheobronchial mucus accumulation and plugging •Airway obstruction –Blood –Mucus accumulation –Tumor projecting into a bronchus • Atelectasis •Alveolar consolidation •Cavity formation •Pleural effusion
