Lung Cancer
Lung cancer is the leading cause of cancer death worldwide, with 90% of cases being attributable to smoking. It is the second most common cancer, and it is a malignancy that affects either the lung tissue or the airways.

Lung cancer is the leading cause of cancer death worldwide, with 90% of cases being attributable to smoking. It is the second most common cancer, and it is a malignancy that affects either the lung tissue or the airways. Risk factors for lung cancer include cigarette smoking, asbestos, radon and family history of lung cancer. Lung cancer can be sporadic or associated to a hereditary cancer syndrome.
Hereditary cancer syndromes are encountered in all medical specialties. Although they account for about 5% of all malignancies, it is of special importance to identify these patients because, unlike patients with sporadic cancers, they require special, long-term care as their predisposition can cause them to develop certain tumors at a relatively early age. Most hereditary cancers are associated with a “germline mutation” that will be present in every cell of the human body. Identification of patients at risk of inherited cancer susceptibility is dependent upon the ability to characterize genes and alterations associated with increased cancer risk as well as gathering a detailed personal and family history aiding in the identification of the mode of inheritance as well as other family members at risk of suffering from this susceptibility. Most hereditary cancer syndromes follow an autosomal dominant inheritance, and the penetrance is high.
The Igenomix Lung Cancer Precision Panel provides a comprehensive analysis of the most common genes responsible for the development of a malignant growth in the airways or lung tissue using next-generation sequencing (NGS) to fully understand the spectrum of relevant lung cancer predisposition genes.
