Study Notes

Screening Tests

Screening tests are used to check for the presence of disease in individuals who are not showing symptoms.
Diagnostic tests are confirmatory tests done after the individual is exhibiting symptoms.

Reasons for Screening

Early detection allows for improved prognosis and outcomes for the patient with a disease.
Reduce the risk of progression of disease.
Reduce mortality and morbidity rates by providing early intervention.

Government Funded Screening Tests

Bowel Cancer:
- Fecal Occult Blood Test (FOBT) is used to detect hidden blood in stool samples.
- Self-collected sample can be done at home and sent for analysis.
- Recommended for individuals aged 45 to 74 years old.
- Repeat every 2 years.
Breast Cancer:
- Mammogram is an x-ray that provides an image of the breast tissue.
- Recommended for individuals aged 50 to 74 years old.
- Repeat every 2 years.
Cervical Cancer:
- HPV test screens for the presence of Human Papillomavirus infection.
- HPV is the main risk factor and the cause of cervical cancer.
- High-risk HPV subtypes include 16 and 18.
- Recommended for individuals aged 25 to 74 years old.
- Repeat every 5 years.
- Can be done via self-collection of a vaginal swab or clinician-collected sample using a speculum.

Tests Not Recommended for Screening

Ovarian Cancer:
- CA 125 blood test and transabdominal/transvaginal ultrasound are not recommended for asymptomatic, low-risk women.
Prostate Cancer:
- PSA test is not recommended for screening asymptomatic, low-risk individuals.
Skin Cancer:
- Screening asymptomatic individuals is not recommended.
- Education is recommended to raise awareness of early signs and symptoms.

WHO Criteria for Screening Programs

Important Health Problem: The condition should be a significant health issue with identifiable early stages.
Suitable Test: The test should be simple, safe, precise, validated, and acceptable for the population.
Available Treatment: Effective treatment options and facilities for diagnosis and treatment should be readily available.
Evidence-Based: The screening program should be supported by robust evidence, including randomized controlled trials demonstrating a reduction in mortality or morbidity.
