 Symtoms

There are variety of symptoms of lung cancer including difficulty in breathing, coughing of blood ,chest pain,loss of appetite,weight loss and general fatigue.Some lung cancers do not cause any noticeable symptoms until they are quite advanced and have to spread to other parts of the body.

 
 

 Treatment

 

 

Drug treatment (chemotherapy) is the usual treatment for small cell lung cancers, because they usually spread too quickly for surgery to be useful. Radiotherapy is also often used. For the other types of lung cancer, surgery is first used to remove the main tumour, if it has not spread too far. If surgery is not possible, then radiotherapy is used instead. Depending on the type of tumour and how advanced it is, chemotherapy can be used in different ways: either to shrink the tumour before surgery or after surgery to kill off any remaining cancer cells.


  Facts
