Can a blood test screen for cancer?
Many people ask whether there is a simple blood test that can detect cancer early. The answer is: sometimes, but not always.
Blood tests can help identify signs that may suggest cancer, such as:
✔️ Abnormal blood cell counts
✔️ Elevated tumour markers in certain cancers
✔️ Signs of inflammation or organ dysfunction
However, no single blood test can reliably screen for all cancers. Depending on your age, s*x, family history, and risk factors, recommended screening tests may include:
🔹 Cervical screening (Pap smear)
🔹 Mammograms
🔹 Colon cancer screening
🔹 Prostate cancer testing
🔹 Skin examinations
📞 Speak to your GP about which screening tests are appropriate for you and whether any blood tests may be helpful as part of your assessment.
