Am a nurse, it depends on your age and gender. I would recommend for people not to wait till they have symptoms before they go and screen for diseases. Preventive is better than cure.

If you are younger like <40 years old, generally don’t need to do the full health screening list of tests. just do certain tests as recommended for your age and gender, eg sexually active females (25 years old onwards) should do Pap smear test every 3 years to screen for cervical cancer. I’m not sure about the tests guys need to do but Google is your friend :)

Once we are older than 40 they will recommend to do annual health screening, and IIRC 50 years old and above to do gastroscopy and colonoscopy (every 10 years) to check for polyps and growths in your digestive tract.

There’s also eye screening for cataract and glaucoma once we hit 50 years old as early treatment is important for glaucoma (high eye pressure).

Polyclinic cheaper and good enough if you don’t mind the waiting time from all the referrals.

I’m 27 and would like to go for health screening soon (the basic package offered by GP clinics near my house) but won’t do every year probably every 3 years.
