Dr. Tarang Krishna, an oncologist, advocates for regular cancer screenings for individuals over 40, recommending tests such as Liver Function Test (LFT), Complete Blood Count (CBC), Kidney Function Test (KFT), Prostate-Specific Antigen (PSA), and Carbohydrate Antigen 19-9 (CA-19.9). However, Dr. Arun Kumar Giri, Director of Surgical Oncology at Aakash Healthcare, cautions that while tests like CBC and LFT are useful for assessing general health, they do not specifically diagnose cancer. He warns that tumour markers such as PSA and CA-19.9 can lead to confusion, as they may elevate due to non-cancerous conditions, resulting in false reassurance, unnecessary anxiety, and overdiagnosis. Evidence-based guidelines suggest that cancer screenings should be tailored to individual risk factors, including age, gender, and lifestyle. Recommended screenings include regular mammograms for women, colorectal cancer screening for both genders, and low-dose CT scans for high-risk individuals. Dr. Giri concludes that preventive healthcare should focus on sustainable wellness and early detection of chronic diseases rather than blanket testing.
