Take the analogy of a car. The car need to be checked regularly for the proper and optimal functioning and good life-span of its engine. Similarly, the human body runs as much as the engine. In order to prevent costly repair to the engine or avoid expensive medical bill, the best is to have a regular body check-up and screening to detect early diseases. If found early, it is easy to treat and take remedial action.
The generally employed methods include the blood and urine screening, radio-logical and other imaging screening such as the CT scan, MRI scan, bone scan, body fat scan. Biopsy scan can be slightly more invasive if a particular lesion is suspected of new growth or predisposed to malignancy. PAP smear is done for lady from the start of sexual activity until the age of menopause. PSA is done exclusively for male.
