What is Lung Cancer?
    It is the type of cancer that appears in the 
lungs It is the disease in which cells of the 
lungs divide abnormally and uncontrollably
How common is it?
   It is the most common type of cancer, risking 
more lives than any other cancers diagnosed 
cancer in the world. It is also the biggest 
contributor to cancer-related mortality, 
resulting in over 1.38 million cancer deaths 
per year worldwide.
Who can develop lung cancer?
• Smokers: The people who smoke are at 
greater risk of developing cancer. Although, 
the risk can minimize if the person reduces or 
quits smoking. 
• Non Smokers: It can also develop in people 
who do not smoke but are exposed to passive 
smoking. However, the chances of developing 
among non-smokers are very minimal.
Symptoms 
Coughing, accompanied with blood
Wheezing
chest pain
weight loss
Hoarseness
extreme body fatigue
swollen lymph nodes
Types 
• Small cell lung cancer (SCLC): This type occurs mainly in 
chain smokers. Its treatment requires combination therapy 
but it depends on the diagnosis stage.
• Non-small cell lung cancer (NSCLC): This type covers a broad 
range which has a similar pattern. It further consists of types 
like squamous cell carcinoma, large cell carcinoma, and 
adenocarcinoma. This type of cancer is seen in the majority 
of people, nearly 85% of the cases affected by lung cancer. 
Every subtype of NSCLC has a specific treatment line.
Different types of treatments
• Surgery (Lobectomy) is an option when cancer has not spread in other parts of 
the body.. The surgery is called a Lobectomy. It is done for NSCLC. Mostly done 
through thoracotomy where the side of the chest is cut open.
• Radiation therapy: Traditional radiation therapy such as 3DCRT or IMRT-6 is used 
widely for treatment in both male and females. The number of sessions required 
for radiation therapy depends upon the stage of cancer and how effectively the 
patient takes up the initial few doses of radiation therapy. 
• Radiofrequency Ablation: RAF is sometimes used as a treatment option based 
on other co-morbid conditions of the patients
• Chemotherapy: It can be used for both types of cancers. There are many drugs 
available and approved by FDA which can be successfully used to treat a single 
treatment or adjuvant therapy. The first line of treatment for small cell lung 
cancer is chemotherapy whereas, in non-small cell lung cancer, it can be used pre 
or post-surgery.
• Cryoablation: The cells are freezed at -160 degrees and killed. It is also called 
cryotherapy or cryosurgery. The effects on other cells or healthy tissues are 
minimal and the side effects are easily controllable.
• Immunotherapy: In immunotherapy, patients’ immune system is activated to 
fight against the cancer cells, thereby inhibiting the growth and killing the cells.
