Lung Cancer Flashcards
(18 cards)
What are the two types of lung cancer?
Small cell lung cancer (SCLC)
Non-small cell lung cancer (NSCLC)
What is the most common type of cancer?
Non-small cell lung cancers - 85%
most aggressive type of lung cancer?
Small cell lung cancer
Symptoms of lung cancer:
- Persistent cough
- Shortness of breath
- Chest pain
- Coughing up blood (haemoptysis) or sputum
- Unexplained weight loss
- Fatigue
How is lung cancer diagnosed?
Chest CT/Xray - visualise masses
biopsy from brochoscopy
PET scan - to see areas of most metabolic activity
Where are 70% of the tumours found?
Large bronchi
What types of lung cancer fall under Non-small cell lung cancer?
Squamous cell,
large cell,
Adenocarcinoma
Risk factors for lung cancer?
Smoking
Radon gas exposure
Air pollution
Family history
Occupational exposure eg: asbestos
Risk factors for lung cancer?
Smoking
Radon gas exposure
Air pollution
Family history
Occupational exposure eg: asbestos
5 year survival rate for small cell lung cancer vs non-SCLC
- 25% for NON
- 6% for SCLC
Role of PET scans in cancer diagnosis
Helps assess whether cancer has metastasised as it detects areas of increased cellular activity.
What is the difference between signs and symptoms of a disease
Signs:
Objective evidence of a disease that can be observed, measured detected by a HCP
Like fever, rash, abnormal heart rate and lab results
Vs
Symptoms:
Experiences reported by the patient which can’t be observed by a HCP
Like fatigue, nausea, shortness of breath, dizziness and pain
What is pleural effusion
Accumulation of fluid in the pleural space, pleura= membrane surrounding lungs
The fluid build up can compress the lungs and lead to difficulty reaching
How is pleural effusion caused in lung cancer?
Common complication - indicates advanced disease
Tumour can spread into the pleura/invade lymph nodes = inflammatory response = fluid accumulation
Metastasis to lymph nodes can also block drainage of fluid
Leads to SOB and chest discomfort and cough, fluid needs to be drained
Haemoptesis
Coughing up blood
Signs of lung cancer
- anorexia and weight loss
- clubbing
- collapse, pleural effusion
- horners syndrome
- signs of metastasis - neuro/bonepain
- lymphadenopathy - swollen lymph nodes
- stridor
Lymphadenopathy
Swelling of lymph nodes, relates to malignancy
Horners syndrome
Sign of lung cancer:
Drooping eyes (ptosis)
Constricting pupil (miosis)
Loss of facial sweating (anhydrous is)
