Lung HealthDiagnostic Imaging A cough deserves attention when it persists, changes, or comes with warning signs—not because its sound can identify cancer.

Joint HealthOsteoarthritisDiagnostic Testing The first warning signs are usually joint pain during or after activity, stiffness after rest that generally lasts under 30 minutes, and gradually reduced movement. Knees may hurt on stairs, hips when putting on socks, and hands when gripping. Blood tests cannot confirm osteoarthritis; a hot, rapidly swollen joint needs urgent assessment. […]

DVTLeg SwellingDiagnostic Testing New, unexplained swelling in one leg needs same-day assessment, even if the pain is mild.

Mental HealthClinical AssessmentTest Limitations Schizophrenia symptoms can include hallucinations, delusions, disorganized speech, reduced motivation, and cognitive difficulties.
