Doctors typically diagnose two lung cancer types

• Non-small cell lung cancer
• Small cell lung cancer 

Symptoms 

Symptoms of lung cancer occur only when the disease is progressing and lung cancer symptoms are followed by coughing up blood, headache, shortness of breath, weight loss and chest pain. There are no signs and symptoms of lung cancer in the early stages.

Diagnosis

Diagnosis of lung canceris confirmed by biopsy which is usually performed by CT-guidance or bronchoscopy and the most common age for lung cancer diagnosis is 70 years. Once lung cancer has spread into metastatic tumors it’s generally not curable but treatable. There are treatments available to decrease signs and to help you live longer. Adanced lung cancer patients can survive an average of 5 years after diagnosis. Lung cancer cannot be prevented but you can minimise the risk of diagnosis if you stop smoking now.
