Forms of Lung Cancer Associated With EGFR Mutation
Lung cancer can be categorized into two main forms: non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer accounts for around 80 to 85 percent of all reported lung cancer cases. It can be further divided into three subtypes:
– Squamous cell carcinoma: This subtype accounts for around 30 to 35 percent of non-small cell lung cancer cases. It often starts around the bronchial tubes.
– Adenocarcinomas: This subtype accounts for around 60 percent of non-small cell lung cancer cases. It tends to affect the outer part of the lung.
– Large cell carcinoma: This is a rare form that may begin anywhere in the lungs. However, it may spread more quickly than the other subtypes.
It is estimated that more than 32 percent of non-small cell lung cancer cases around the world involve EGFR mutations. [3]
