Precision Medicine in Lung Cancer: Challenges and Opportunities in Diagnostic and Therapeutic Purposes.

Lung cancer is one of the leading causes of cancer death among both men and women, making up almost 25% of all cancer deaths. Precision medicine shows promise for improving many aspects of health and healthcare, including tests, drugs, and other technologies that support innovation, with the possibility of new partnerships with scientists in a wide range of specialties. Non–small-cell lung cancer (NSCLC) has become a prominent example of the success of precision medicine in treating solid tumor malignancies. The first step in this process involves new bloodbased diagnostics, which can now noninvasively provide clinically useful information. However, the identification of novel biomarkers that could be used in early diagnosis is urgently needed, especially for guiding initial therapy and predicting relapse or drug resistance following the administration of novel targeted therapies
