Lung Cancer Explained Awareness

Lung cancer is one of the most serious and common types of cancer. In lung cancer there is an abnormal growth of cells in the lungs. These abnormal cells stick together to form a cluster called tumour. Every year more than 1.8 million people fall prey to lung cancer and 1.6 million die. Someone somewhere dies of lung cancer every 30 seconds and survival rate depends on an early diagnosis. The chances of developing lung cancer can be considerably reduced by avoiding certain risk factors like smoking, passive smoking or exposure to harmful chemicals.

Types of Lung Cancer

When the cancer cells first begin growing in the lungs then it is known as primary lung tumour. Gradually they break and travel via blood vessels to bones and grow there and referred to as secondary tumour (metastasis).  There are a number of different types of Lung Cancer, but the two most common ones on the basis of type of cells in which cancer begins are:

  • Non-Small Cell Lung Cancer (NSCLC) - This is most common type and accounts for around 80 per cent of cases.
  • Small Cell Lung Cancer (SCLC) - It is less common type and generally spreads faster than the NSCLC.

The treatments depend upon the type of lung cancer you have.
