Health Screening Profile Image

Health Screening

Health screening is designed to identify disease in a community early, thus enabling earlier intervention and management in the hope to reduce death and suffering from a disease.

Overview

Screening can detect medical conditions at an early stage before symptoms present while treatment is more effective than for later detection. In the best of cases lives are saved.

Like any medical test, the tests used in screening are not perfect. The test result may incorrectly show positive for those without disease, or negative for people who have the condition.

Limitations of screening programmes can include:

  • Screening incurs costs for a majority of people who do not need treatment.
  • Adverse effects of screening procedure (e.g. stress and anxiety, discomfort, radiation exposure)
  • Stress and anxiety caused by a false positive screening result.
  • Unnecessary investigation and treatment of false positive results

Simply put. There are benign causes and worrisome ones. If the frequency is unusual and lasting longer than a minute or two, I would advise you to get it checked. At the A&E, our practice would be to first examine where the bleeding occurs, if it’s at the front and ea...

Light headed sensation when standing up from sitting or lying position may be quite normal for a lot of people, especially young female. This is called postural hypotension. Management usually consists of being aware of the issue and more cautious when standing up. Some people may feel light heade...

Very interesting question and symptoms that you are experiencing. I can sense your frustration in trying to resolve this problem from the numerous consultations and treatments you have sought. From clinical practice, I have found that trigger points (TP) can be a challenge to t...

Just to add to Dr Quan's answer, an enlarged spleen is a definite "No" to playing contact sports. You see, if the spleen is enlarged and struck during contact sports, it can cause significant bleeding and pain. In fact, it could lead to shock. This is a concern in younger pa...

Thank you for the question. The risk of acquiring an STI from unprotected hand job is extremely low. There is not contact with blood and body fluids so there is no risk of infections like HIV, chlamydia or gonorrhoea. If the person has viral warts or herpes viral infection of h...
