What a Positive Cancer Blood Test Result Means
What a “Positive” Result Actually Means
Getting a “positive” result on a cancer-related blood test can sound alarming. Yet in this context, it simply means that something abnormal was detected. That could be an elevated tumor marker, an unusual blood cell count, or an irregular protein level. None of them confirms blood cancer on their own.
These results often act as early signals, prompting further investigation. Sometimes, false positives can happen, especially with tumor markers like CA-125 or PSA. Which can rise for reasons unrelated to cancer.
Next Steps After a Positive Blood Test
If you’ve received a positive or abnormal result from a cancer-related blood test, the next steps are important. While it’s completely natural to feel anxious, keep in mind that this result is often just the beginning of a larger diagnostic process, not a conclusion.
1. Schedule a Follow-Up Appointment
Your first move should be to talk with your healthcare provider. They will explain the results, place them in the context of your medical history, consider possible non-cancer causes, and recommend any necessary next steps.
2. Repeat the Blood Test (If Advised)
Sometimes, abnormalities appear due to lab errors, temporary illnesses, or other non-serious factors. Your healthcare provider might suggest repeating the test after a short interval to confirm whether the results are consistent.
3. Undergo Imaging Tests
If the concern persists, imaging studies like CT scans, MRIs, ultrasounds, or PET scans may be ordered to check for tumors or other internal abnormalities. These tests help assess the size, shape, and location of anything unusual.
4. Receive a Biopsy
A biopsy, where a small tissue sample is taken and examined under a microscope, is often used to confirm or rule out cancer. The type of biopsy depends on the suspected area, such as needle, surgical, or endoscopic.
5. Referral to a Specialist
Depending on the findings, your healthcare providers may refer you to a specialist such as an oncologist, hematologist, or radiologist for further evaluation and care planning.
