You can use health screening to determine whether you have a certain illness or medical condition. This is significant since not all diseases have symptoms, and problems found during a health screening may be addressed sooner. In most cases, this increases the likelihood of success and decreases the likelihood of complications, suffering, or even death. How do you choose which disorders to check for among the numerous diseases that exist? Most, if not all, health screening packs will include tests for illnesses that are simple to detect and that are significant health issues.
For instance, you can check if you’re obese, a serious health problem that affects the world’s population today, by taking your weight and height. Additionally, screening tests must be non-invasive and sensitive (correct). For instance, health screenings frequently entail simple radiological tests like x-rays and ultrasounds as well as blood, urine, and stool analysis. Biopsies and other invasive diagnostics are not frequently provided.
What Are The Purposes Of Health Screening Exams?
There isn’t a screening test available for every illness. Based on the following factors, healthcare professionals offer health screening tests for health conditions:
- It’s a significant public health issue that affects a large enough population to warrant the expense of screening.
- It has a substantial impact on a person’s life expectancy and quality of life.
- There is a suitable course of treatment.
- It has an early stage throughout which no symptoms would be present, but early discovery and treatment would greatly enhance long-term results.
- There is a quick and inexpensive screening test available.
Basic Health Screening
A basic health screening often entails a physical exam by your specialist, bio-physical measures (weight, height, body mass, visual acuity, and colour vision), as well as tests of the blood and urine. Blood tests typically check for:
- Blood count
- Blood sugar
- Blood cholesterol
- Kidney function
- Liver function
Blood tests typically screen for cholesterol levels, renal function, liver function, blood counts (to check for anaemia, aberrant immune cells, and irregular clotting factors), glucose level (a diabetes screening test), and cholesterol levels. The typical purpose of a urine test is to look for infections, sugar in the urine (which may indicate diabetes), proteinuria (which may indicate early kidney problems), or blood in the urine (which may indicate infections, tumours, kidney stones, and other renal conditions).
Screening centre may offer the option of a chest x-ray, which can pick up abnormalities of the lung, or an electrocardiogram (ECG) which is a screening test for heart diseases. Usually, it takes between 30 minutes to three hours to finish these simple items. These packages, which can be used once every three years to once a year, are available to younger individuals, particularly those with no significant family background of hereditary disorders and no significant past medical history.
Comprehensive Health Screening
The blood sample may be used in more comprehensive health screening packages, in addition to the tests described above, to screen for additional requirements like:
- Cancer biomarkers
- Thyroid hormone levels
- Sexually transmitted illnesses
- Testing for hepatitis A and B
- ABO blood type
In addition, a stool test that looks for blood in the stools can be used as a colon cancer screening test. However, keep in mind that other illnesses, such as piles or haemorrhoids, can also cause blood in the stool. All women who had sexual contact between the ages of 25 and 65 are often offered a Pap smear. Unless your doctor advises differently, this is typically done every three years to check for cervical cancer.
X-rays are used in the bone minerals density (BMD) test to check for osteoporosis, a disease where the bones are brittle and increase the risk of fracture. All women 65 years of age and older should get it, as well as anyone else with risk factors. To determine your risk of osteoporosis, you can talk to your doctor or take the Osteoporosis Self-Assessment Tool for Asians (OSTA). Visit your doctor to be evaluated for osteoporosis if your risk is moderate or high.
All women over the age of 40 should get a mammogram or a breast ultrasound to check for melanoma and other problems. It should be done every year for women between the ages of 40 and 49. Every two years of screening is advised for women 50 years of age and older. There may also be other radiological examinations available, such as:
- Abdominal ultrasounds to check for diseases affecting the kidneys, gallbladder, and liver
- Ultrasonography of the pelvic (for females) to check on uterine and ovarian health
- Ultrasonography of the neck to check for thyroid gland issues
Different centres could offer a wide variety of additional testing. Depending on the number of tests performed, the comprehensive health exam might last anywhere from an hour to a whole day.
Why You Need to Get Screened for Colorectal Cancer
For instance, colorectal cancer is a disease that fits the description above. The majority of colorectal malignancies take years to develop slowly. However, a growth of tissue or tumour typically starts as a non-cancerous polyp on the inside of the colon or rectum before turning into cancer. Although these polyps typically don’t show any symptoms, they can occasionally develop into a malignancy. Thus, when a pre-cancerous polyp is discovered during colon cancer screening and eliminated, cancer is thereby prevented without having an adverse impact on a person’s health or life expectancy.
However, based on the stage of the tumour when it was discovered, the five-year survival rate for colorectal cancer varies from 6% to 74% when it develops.
Other Screening Tests
In addition to getting screened for colon cancer, you should discuss the following with your healthcare provider:
- Typically, screening for breast cancer should start around age 40. (Except for those who are at high risk). However, all women should discuss their risk factors with their doctor before deciding when to begin screening and how frequently.
- Beginning at age 21, women should undergo Pap tests every three years as a cervical cancer screening. Between the ages of 30 and 65, Pap tests alone every three years can be replaced by a combination of Pap tests and human papillomavirus (HPV) tests every five years.
- A dermatologist frequently performs skin cancer screenings. If you have a history of skin cancer or have fair skin that is vulnerable to sun damage, your doctor will advise you to use this product. During a skin examination, the doctor will look for pigmented areas on your skin that seem odd in size, shape, colour, or texture. They will also examine your moles and scars to determine which ones require additional testing.
- You should also routinely undergo a blood test as an adult (often once a year) to evaluate your lipid panel, which is a full cholesterol test used to determine the ratio of “good” and “bad” triglycerides and cholesterol. (a form of fat) in your blood. Your chance of developing heart disease can rise if you have excessive triglycerides.
