Lung cancer is one of the deadliest cancers that remains difficult to manage. There are approximately 225,000 new cases and 160,000 deaths annually. Lung cancer is the second most common cancer in men and women, at about 15%, but accounts for 25 to 30% of annual cancer deaths. In women, lung cancer actually causes more deaths than even breast cancer. These numbers confirm this is a disease with serious problems and high morbidity and mortality. Most patients with early stage lung cancer are completely asymptomatic and won't even know they have cancer. Once the patient starts developing symptoms such as worsening cough, hemoptysis, chest pain, or bone pain, the cancer has already developed into a later stage and will be much harder to treat. Fortunately, within the last decade, there has been progress in lung cancer screening protocols to detect cancer at earlier stages, when it is more treatable. There has also been an increase in understanding about the genomics of lung cancer, leading to development of more targeted therapies to fight cancer based on the cancer's genetic makeup.
