“…A false positive occurs when a result that should be negative is reported as positive, and the opposite occurs in a false negative. For example, in a previous investigation involving a total of 70 patients, bronchoscopy-based lung cancer diagnosis presented 18.2% of false positives and 16.2% of false negatives, while the same diagnosis carried out using computerized tomography yielded 36.4% of false positives and 18.9% of false negatives [3]. Screening tests are also evaluated by this measure of reliability.…”

Quando presentes, os sinais mais comuns de câncer de pulmão são tosse, rouquidão, perda do apetite, falta de ar, fadiga e tosse com expectoração com sangue SARAIVA, 2010). Tais problemas podem ser evitados pela investigação precoce da doença e remoção do tumor por um processo cirúrgico ou tratamento com quimioterapia (BARROS et al, 2006;FERNÁNDEZ-BUSSY et al, 2015).…”
