Cancer Tests Over 40: What Doctors Actually Recommend?

Individuals over 40 are advised by some oncologists to undergo regular medical tests for cancer prevention. These suggested tests include Live Function Test (LFT), Complete Blood Count (CBC), Kidney Function Test (KFT), Prostate-Specific Antigen (PSA), and Carbohydrate Antigen 19-9 (CA-19.9).

However, other medical experts stress that general health tests like CBC, LFT, and KFT are indicators of overall well-being but do not independently diagnose or prevent cancer. They warn that universal screening with tumour markers like PSA and CA-19.9 for everyone over 40, especially without symptoms or risk factors, can lead to false reassurance, unnecessary anxiety, and overdiagnosis.

Recommended cancer screenings are evidence-based and vary by age, gender, lifestyle, and personal risk profile. These include mammograms and Pap smears for women, colorectal cancer screenings for both men and women, and low-dose CT scans for high-risk smokers. PSA testing might be considered after informed discussion with a doctor, particularly if risk factors are present.

A comprehensive preventive health check-up in one's 40s should include blood pressure and sugar tests, lipid profile, weight assessment, CBC, liver and kidney function tests, thyroid testing if needed, vaccination review, and lifestyle counseling. The primary goal of preventive healthcare is sustainable wellness and early identification of common chronic diseases through appropriate testing.
