One-liner
This episode is a comprehensive review of risk factors and screening guidelines, covering everything from smoking history (AAA, bladder cancer) and age-related cancers (prostate/breast) to specific protocols for colonoscopy, cervical cytology, and prenatal care.
High-yield summary
- Abdominal Aortic Aneurysm (AAA): While smoking is a major risk factor, the greatest predisposing risk factor for rupture is damage to the aneurysm wall. Screening is recommended in men aged 65–75 with a history of smoking.
- Hepatocellular Carcinoma (HCC): The most important preventive measure is Hepatitis B vaccination, as HBV infection can cause HCC, and vaccinating against HBV also prevents HDV.
- Colon Cancer Screening: Preferred screening method is colonoscopy every 10 years (age 50–75). If FOBT or flexible sigmoidoscopy are positive, the next step is always a full colonoscopy.
- Cervical Cancer: The primary risk factor is exposure to high-risk Human Papillomavirus (HPV), especially types 16 and 18. HPV causes squamous cell cancer, not adenocarcinoma.
- Preeclampsia/Preterm Labor: High-yield risk factors include a prior history of preeclampsia or nulliparity for preeclampsia; bacterial vaginosis for preterm labor.
- Lung Cancer Screening (LDCT): Recommended by USPSTF for men and women aged 55–80 with a >30 pack-year smoking history who currently smoke or quit within the last 15 years.
Learning objectives
- Identify the primary risk factor for AAA rupture, distinguishing it from general risk factors like smoking.
- Differentiate between screening guidelines for various cancers (e.g., colonoscopy interval vs. flexible sigmoidoscopy).
- Recall the specific high-yield risk factors for obstetric complications (e.g., preeclampsia, placental abruption).
- Understand the role of HPV in cervical cancer pathogenesis and the difference between squamous cell and adenocarcinoma types.
- Apply knowledge of screening guidelines based on age, smoking history, and duration since quitting.
