According to BMJ.,The lists the common conditions that the authors claim are being overdiagnosed:
Breast cancer – a systematic review suggests that a third of breast cancers detected by screening might not cause harm or early death.
Thyroid cancer – detecting thyroid abnormalities is common, but risk low.
Gestational diabetes – an expanded definition means one in five pregnant women are diagnosed inappropriately.
Chronic kidney disease – an expanded definition means 10% of Americans are classified as having the disease but fewer than 1 in 1000 will develop end-stage kidney disease.
Asthma – asthma is often underdiagnosed, but a third of those being treated may not have the condition.
Pulmonary embolism – potentially fatal but new, sensitive tests detect smaller clots that may not require treatment.
Attention deficit hyperactivity disorder (ADHD) – a widened definition of this condition has led to overdiagnosis
Osteoporosis – expanded definitions means many women being treated even if at low risk of fractures.
Prostate cancer – Prostate specific antigen (PSA) may lead to overdiagnosis in more than 60% of men.
High blood pressure – authors suggest “substantial overdiagnosis” of high blood pressure.
High cholesterol – almost 4 in ever 5 people treated for high cholesterol may actually have near-normal cholesterol levels.
