Many people receive health check-up notifications but then get confused, thinking, "Is it my turn this year?" and end up postponing it. National health check-ups have set eligibility criteria and cycles, so if you organize this information once, you won't miss out. Sihung Geomo-dong Internal Medicine, which provides medical care in Geomo-dong, Sihung, will guide you through the national health check-up process, from eligibility criteria to the 5 major cancer screenings and pre-check-up preparations.
National Health Check-ups: Who Can Receive Them and When?
- Adults aged 20 or older are eligible for national health check-ups every two years.
- Individuals born in an even-numbered year receive check-ups in even-numbered years, and those born in an odd-numbered year receive them in odd-numbered years, alternating.
- Non-office workers can receive check-ups annually.
Basic items include blood tests, urine tests, vision and hearing tests, chest X-rays, and blood pressure measurements. Additionally, age-specific supplementary tests can check for dyslipidemia, osteoporosis, and mental health evaluations. If abnormal findings are observed in the check-up results, further detailed examinations are directly linked, allowing for one-stop management at a single location without the need to visit multiple hospitals. Early detection and consistent management of increasing cases of obesity, abnormal liver function, and early-stage hypertension are also possible through these regular check-ups.

National 5 Major Cancer Screenings: What Tests Are Included?
The 5 major cancer screenings supported by the government include gastric cancer, colorectal cancer, liver cancer, breast cancer, and cervical cancer. If you meet the age and condition requirements, you can receive these screenings for free or with only a partial co-payment, and Sihung Geomo-dong Internal Medicine can perform these tests in one place.
| Cancer Type | Test Method |
|---|---|
| Gastric Cancer | Gastroscopy |
| Colorectal Cancer | Fecal occult blood test or colonoscopy |
| Liver Cancer | Combined liver ultrasound and blood test |
| Breast Cancer · Cervical Cancer | Performed according to age-specific screening cycles |
While breast cancer and cervical cancer have different screening cycles depending on age, regular check-ups are paramount as early detection leads to better treatment outcomes. It is advisable for individuals with a family history or women over 40 not to skip periodic cancer screenings.


Digestive Health Check with Gastroscopy and Colonoscopy
Gastroscopy is a useful test for checking for early signs of gastric cancer, as well as gastritis, gastric ulcers, and Helicobacter pylori infection. Colonoscopy can prevent the progression to colorectal cancer by early detection and removal of colorectal polyps. If you are curious about the examination procedure, checking the Examination Guide in advance can reduce your burden on the day of the examination.
Why Get an Ultrasound Exam Not Included in National Check-ups?
Ultrasound examinations are not included in the national check-up items, but they are useful tests that can directly confirm the condition of organs.
- Abdominal Ultrasound: Checks for abnormalities in the liver, gallbladder, pancreas, and kidneys.
- Thyroid · Carotid Artery Ultrasound: Detailed check of blood vessel health and circulatory status.
These additional examinations can enhance the completeness of your check-up if performed selectively based on your individual lifestyle or family history.

Before Your Check-up, Just Follow These Instructions
- Be sure to adhere to the advised fasting time and medication instructions.
- Avoid overeating and alcohol the day before.
- Visit in comfortable clothing on the day of the examination.
