The Claim
Unexplained, sustained elevated vitamin B12 levels exceeding 1000 pg/L warrant a comprehensive clinical assessment to evaluate for underlying neoplastic disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If your vitamin B12 levels are way higher than normal for no clear reason, doctors should check for possible cancer, because it might be a sign something serious is going on inside your body.

What the research says
1 studyStudy: Elevated Vitamin B12, Risk of Cancer, and Mortality: A Systematic Review
This study found that when people have very high B12 levels for no clear reason, they’re more likely to have certain types of cancer — so doctors should check for cancer in those cases, just like the claim says.
