「爸爸 45 歲確診大腸癌，我幾歲該開始檢查？」
答案可能是：35 歲！
有大腸癌家族病史，篩檢時間不能只看自己的年齡，也要看「誰罹癌、幾歲確診」。
📌 哪些人需要提早做大腸鏡？
如果有：
🔹 一位一等親在 60 歲前確診大腸癌；或
🔹 至少兩位一等親罹患大腸癌，不論確診年齡。
通常建議從以下兩個時間，選「比較早的」開始：
✅ 40 歲
✅ 比家人最早確診的年齡提前 10 年
例如：
👉 媽媽 55 歲確診 → 你從 40 歲開始
👉 爸爸 45 歲確診 → 你從 35 歲開始
📅 多久檢查一次？
上述較高風險族群，通常建議每 5 年做一次大腸鏡，再依檢查結果調整。
如果只有一位一等親在 60 歲或之後確診，通常仍建議從 40 歲開始篩檢，但不一定需要每 5 年做大腸鏡，應與醫師討論。
💡 一等親包括：父母、兄弟姊妹、子女。
大腸鏡除了能發現癌症，也能切除癌前息肉，降低未來罹癌的風險。
❤️ 今天就問家人兩個問題：
「誰得過大腸癌？當時幾歲？」
把答案帶給腸胃科醫師，就是保護自己的第一步。
若家人很年輕就罹癌，或多人罹癌，也可能需要遺傳風險評估。
📌 有血便、不明原因貧血或持續排便習慣改變，請及早就醫，別等到篩檢年齡。

If your parent had colon cancer, do you still have to wait until age 45 to get screened?
🩺 You may need to start colonoscopies at age 40—or even earlier!
The key question is: How old was your family member when they were diagnosed?
👇 Let’s look at some examples!
“My dad was diagnosed with colon cancer at 45. At what age should I start screening?”
The answer may be: Age 35!
If you have a family history of colon cancer, screening recommendations depend not only on your age, but also on which family member had cancer and how old they were at diagnosis.
📌 Who may need an earlier colonoscopy?
If you have either of the following:
🔹 One first-degree relative diagnosed with colon cancer before age 60, or
🔹 At least two first-degree relatives diagnosed with colon cancer, regardless of their age at diagnosis.
Screening is generally recommended to begin at whichever comes first:
✅ Age 40
✅ 10 years before the youngest age at diagnosis in your family
For example:
👉 Mom diagnosed at 55 → Start at age 40
👉 Dad diagnosed at 45 → Start at age 35
📅 How often should you get screened?
For these higher-risk groups, a colonoscopy is generally recommended every 5 years, with adjustments based on the results.
If only one first-degree relative was diagnosed at age 60 or older, screening is still generally recommended to begin at age 40, but a colonoscopy every 5 years may not be necessary. Discuss the appropriate screening plan with your doctor.
💡 First-degree relatives include parents, siblings, and children.
A colonoscopy can detect cancer and remove precancerous polyps, helping reduce your future risk of developing colon cancer.
❤️ Ask your family these two questions today:
“Who had colon cancer, and how old were they when diagnosed?”
Sharing this information with your gastroenterologist is an important first step in protecting your health.
If a family member developed cancer at a young age, or multiple family members have been affected, genetic risk evaluation may also be appropriate.
📌 If you have blood in your stool, unexplained anemia, or persistent changes in bowel habits, seek medical evaluation promptly. Don't wait until your routine screening age.
