lifetime risk show that men are more likely to get lung cancer but overtime the two
genders are colliding due to the habit of smoking

the long run is very low with only 15% chance of survival for 5 years

What are the main causes of lung cancer? - Answer-There are several key causes of
lung cancer and they are smoking (active and passive), asbestos exposure and family
history

How is family history a reason to get lung cancer? - Answer-Incidences occur due to
family history and genetics such as mutations, hence why children can also get lung
cancer

What does asbestos cause? - Answer-Asbestos exposure is linked with mesothelioma
which while less common is much more dangerous

lung cancer in the inferior lobe as this is the lobe which does most of the initial breathing

nodes it is termed staged 4

3. Metastatic disease is typically palliative treatment either chemo or RT`

What are the typical palliative doses? Explain each: - Answer-Often we can also see a
dose of 20Gy in 5 fractions given, while this is less dose overall, the relative biological
effectiveness is greater due to such a high dose per fraction

36Gy In 12 can also be given but only if there is a survival prognosis of greater than 6
months

How is the patient set up? What variations can occur? - Answer-Patient positioning:
Supine, arms elevated but this can be adapted to either one arm up or both depending
on the patient condition
