Knowing your family's medical history tells you which risks to watch most closely. Answer a few short questions to map your inherited risk across the main categories that run in families — then share the answers with your doctor to guide earlier, smarter screening.
Wherever Singapore-specific guidance exists (MOH Clinical Practice Guidelines), we use it — it's often stricter or differently calibrated than US guidelines. Where it doesn't, we fall back to international standards, and say so.
A few questions
Has this run in your family?
For each category, tell us if a first-degree relative (parent, sibling, or child) has been diagnosed — and at what age, if you know it. The age they were diagnosed matters: the exact threshold that counts as "early" differs by condition, so give your best estimate if you're not sure of the exact age.

📖 Where this comes from
Wherever Singapore has its own clinical practice guideline (MOH CPG), we use it — it's sometimes stricter, and sometimes calibrated differently, than international guidance:
🇸🇬 Cardiovascular: MOH CPG on Lipids defines premature family heart disease as a male relative before 50, or a female relative before 60 — earlier than the commonly-cited US AHA/ACC thresholds of 55 / 65.
🇸🇬 Cancer (colorectal): MOH CPG on Colorectal Cancer Screening — a relative diagnosed at 60 or younger means starting colonoscopy 10 years before their diagnosis age (or 40, whichever is earlier), every 5 years; over 60 means starting at 50, every 10 years.
🌐 Cancer (breast, ovarian & other): no Singapore-specific starting-age formula found, so this uses international guidance (NCCN Genetic/Familial High-Risk Assessment). For breast specifically, recent research (Breast Cancer Surveillance Consortium, 2022) questions whether the commonly-cited "10 years earlier" rule should apply uniformly — treat any computed age as a starting point for discussion, not a fixed number.
🌐 Cancer (same-side clustering): two or more relatives with the same cancer on one side of the family is treated as elevated risk regardless of age at diagnosis — CDC, NCCN, and Singapore's National Cancer Centre (NCCS) all define familial risk this way, because these cancers are common enough that one case on each side is usually unrelated chance.
🌐 Alzheimer's / neurological: early-onset is defined internationally as before 65 (rather than 60) — this is when rare inherited forms (genes such as PSEN1, APP) become relevant. No Singapore-specific family-history threshold was found, though the genetics have been confirmed in Asian cohorts.
🇸🇬 Metabolic: MOH CPG on Diabetes Mellitus treats a first-degree relative with diabetes as a screening risk factor at any age — the more useful Singapore-specific adjustment is the Asian BMI threshold (≥23, vs ≥25 in Western guidelines) for when you yourself should be screened.
This is an informational screening tool, not a diagnosis. Only a doctor can properly assess your personal and family risk — please share these answers with them, especially for any category flagged above.
