Lung cancer is the leading cause of death from cancer in the UK. Each year, 47,000 people are diagnosed with lung cancer in the UK, and 34,700 people die from the disease.
Both squamous cell carcinoma and adenocarcinoma are common types of lung cancer. Of the two, adenocarcinoma is the most common type and begins in the cells of the mucus-producing glands.
