Lung Cancer

Risk Factors

 

Symptoms

Screening Tests


 

As the second top cancer for men and, third for women, lung cancer kills 1.3 million people worldwide annually.  One out of every five persons who died from cancer had lung cancer.  The lung is a common place for metastasis from tumours in other parts of the body. 

 

The risk of lung cancer for the smoker is 15 to 25 times more than that of a non-smoker.  When the smoker stops smoking, the risk of lung cancer drops to two times the risk of a non-smoker after 10 to 15 years.  The best safeguard against lung cancer is still to never smoke; and if you smoke, you should stop now.
 
Surgery, radiation and chemotherapy are the three main methods of cancer treatment.  The type of treatment depends on the size, extent of the disease, the type of lung cancer and the general health of the patient.  Part of a lung or a whole lung may be removed in the treatment of lung cancer.  Before surgery, the patient will undergo a lung function test to assess the functional capacity of the existing lung.  After surgery, these patients may require assisted ventilation for a short period.  Physical activities may also be limited for a short period.  If the remaining lung function is good, the patient will be able to continue a normal life.
 
Certain types of lung cancer are sensitive to chemotherapy treatment.  This form of treatment is increasingly being used in combination with surgery or with radiation.  As newer drugs are discovered and their range of efficacy increases, the use of chemotherapy will increase. Side-effects of chemotherapy such as nausea, vomiting and diarrhoea can be overcome with medications. 

 

Radiation or the use of x-rays to treat lung cancer may be in conjunction with surgery or as a palliative treatment to relieve the pressure symptoms or pain caused by the lung cancer.  Side-effects of radiation such as tiredness, skin rash or sore throat are transient.

Screening Tests

Chest x-ray or CT scan of the chest

 

Confirmed with a biopsy

 

The location(s) of all sites of cancer is determined by additional CT scans, PET (positron emission tomography) scans, and MRI (magnetic resonance imaging)

 

Tests to determine if cancer started in the lung or somewhere else in the body
