Cancer Screening Strategy for 2025 (Thai-English Bilingual Response)

พื้นฐานการตรวจสุขภาพเพื่อรักษาผิดปกติในการทำงานของเซลล์ 2025 (Cancer Screening Strategy 2025)

Introduction (): In 2025, cancer screening strategies remain a critical component of preventive healthcare, with advancements in technology and a better understanding of cancer biology. The World Health Organization (WHO) continues to emphasize evidence-based screening programs that balance benefits, risks, and costs.

Key Principles (หลักการสำคัญ):

1. Evidence-Based Criteria (เกณฑ์ที่พบหลักฐาน):
   • The disease should be sufficiently common to warrant screening.
   • The test should be sensitive, specific, acceptable to the population, safe, and inexpensive.
   • The screening program should ensure adequate diagnostic facilities and high-quality treatment for screen-detected diseases.
   • Screening should be repeated at appropriate intervals for diseases with insidious onset (WHO, 2025).

1. Screening for Specific Cancers (การตรวจสุขภาพสำหรับมะเร็งชนิดเฉพาะ):
   • Cervical Cancer ():
     • Pap smears remain the primary screening tool, with follow-up biopsy for abnormal results.
     • HPV testing is increasingly used, especially in older women (RAG, 2025).
   • Colon Cancer (มะเร็งลำไส้ใหญ่):
     • Screening is recommended for individuals aged 45–75, using colonoscopy, sigmoidoscopy, or fecal occult blood tests (FOBT).
     • Intervals of 5–10 years for colonoscopy, depending on risk factors (RAG, 2025).
   • Breast Cancer (มะเร็งเต้านม):
     • Mammography is recommended for women aged 50–74 every 2 years.
     • Some guidelines now suggest starting at 40 for high-risk individuals (WHO, 2025).

1. Limitations and Biases (ข้อจำกัด):
   • Lead Time Bias ():
     • Screen-detected cancers appear to have better outcomes due to earlier detection, not necessarily improved treatment.
   • Overdiagnosis (การวินิจฉัยเกิน):
     • Some cancers detected by screening may never cause symptoms or progress (RAG, 2025).

1. Recent Advances (ล่าสุด):
   • Liquid Biopsies ():
     • Emerging as a potential tool for early detection, particularly for lung and breast cancers (WHO, 2025).
   • AI and Big Data ():
     • AI-assisted image analysis improves accuracy in radiology and pathology (WHO, 2025).

Patient Safety Considerations (ข้อควรระวังสำหรับผู้ป่วย):

• Always discuss screening options with a healthcare provider, considering individual risk factors and medical history.
• Ensure the screening test is appropriate for the patient’s age and condition.
• Be aware of potential risks, such as false positives/negatives, and unnecessary interventions.
