When diagnosing lung metastases and second primary lung cancer in patients with head and neck cancer, low-dose CT leads to better sensitivity than chest x-ray but does not lead to improved overall ...

Looking at follow-up data, in 2006 the research showed a 10-year survival rate of 80% for lung cancer patients whose disease was spotted by CT screening. The latest report extends those findings ...
