The high mortality rate and rising frequency of cancers are well-known facts. Lung cancer is undoubtedly one of the deadliest of them all. Lung cancer was the second most prevalent cancer in the world in 2020, with more than 2.2 million new cases and 1.8 million fatalities, according to the World Cancer Research Fund International.However, lung cancer, like other cancers, is easier to treat if caught earlier. “The reported 1-year survival rate for stage V is just 15% to 19% compared with 81% to 85% for stage I, which means that the early differentiation of benign and malignant pulmonary nodules, can effectively reduce mortality,” said Xingguang Duan, a scientist from the School of Medical Technology, Beijing Institute of Technology.
