Elevated Plasma Vitamin B12 Levels as a Marker for Cancer: A Population-based Cohort Study. Numerous other cancers have been associated with an increase in B12 levels, including types of breast, colon, and stomach ( Andres, 2013 ). INTRODUCTION: Both venous thromboembolism (VTE) and high plasma vitamin B12 levels (cobalamin, Cbl) are markers of occult cancer and aggressive cancer with a poor prognosis. This article attempts to draw mortality conclusions from 10-year old single B12 level determinations without corrections for the often fatal diseases associated with high levels; high levels demand a careful work up, and should not be attributed to OTC supplementation. J Natl Cancer Inst 2013;105:(23):1799-805. read high levels can be cancer!!!

Arendt JF, Farkas DK, Pedersen L, Nexo E, Sorensen HT. Vitamin B12 levels of at least 550 but less than 650 pg/mL are associated with a 26% increased mortality risk vs. levels below 400 pg/mL. A large Danish population study identified a correlation between high plasma B12 levels and elevated risk of hematological, smoking-related, and alcohol-related cancers ; and cancer patients with elevated B12 levels had higher mortality than those with normal values . In this population-based cohort study, we assessed VTE risk among cancer patients with high plasma Cbl levels. So, instead of high B12 blood levels leading to cancer, maybe cancer leads to high blood levels. Read on to learn more about testing B-12 levels and what the test results mean. HCbl in solid tumors is related to an excess synthesis of transcobalamins by the tumor or an increase in haptocorrin secondary to hyperleukocytosis [ 6 - 8 ]. Background A substantial proportion of patients referred for plasma vitamin B12 (cobalamin [Cbl]) measurement present with high Cbl levels, which have been reported in patients with different cancer types. To assess high Cbl levels and risk of cancer, Arendt and his colleagues used Danish Medical registries to review the records of 333,667 patients without cancer who had been referred for Cbl testing. Hematologic disorders like chronic myelogeneous leukemia, promyelocytic leukemia, polycythemia vera and also the hypereosinophilic syndrome can result in elevated levels of cobalamin. But did do vitamin IV's For years. However, the cancer risk among patients with newly diagnosed high Cbl levels has not been adequately examined. Folic Acid, B12, and Lung Cancer Ebbing and colleagues analyzed data from two studies that included almost 7,000 heart patients treated with B vitamin … A high level indicates a true B12 deficiency.

We aimed to elucidate the role of vitamin B12 in lung cancer etiology via direct measurements of pre-diagnostic circulating vitamin B12 concentrations in a nested case–control study, complemented with a Mendelian randomization (MR) approach in an independent case–control sample. However, the cancer risk among patients with newly diagnosed high Cbl levels has not been adequately examined. HCbl in solid tumors is related to an excess synthesis of transcobalamins by the tumor or an increase in haptocorrin secondary to hyperleukocytosis [6–8]. "Vitamin B12 status was also positively associated with BC risk in women with plasma folate levels below the median value (ORQ4‐Q1 = 1.29; 95% CI 1.02–1.62; Ptrend = 0.03).).
