Now, here’s where things get really interesting. Some studies suggest a link between low B12 and an increased risk of specific cancers. Research has found that those with low B12 were more likely to develop cancer a decade later.
For instance, one study revealed that people who didn’t consume enough vitamin B12 over a year had an increased risk of developing a vitamin B12 deficiency. 1Additionally, researchers have discovered that an increase in B12 levels may be a warning sign for other types of cancers, especially those impacting the blood. 6

FAQs
Does high B12 mean cancer?
High levels of vitamin B12 in the blood do not necessarily mean that someone has cancer. However, elevated B12 levels can be a sign of certain types of cancer, such as:
- Leukemia: A type of cancer that affects the blood and bone marrow.
- Lymphoma: A type of cancer that affects the immune system.
- Multiple myeloma: A type of cancer that affects the bone marrow.
In some cases, high B12 levels can also be a sign of other conditions, such as:
- Liver disease: The liver plays a role in storing and releasing B12, so liver disease can lead to elevated B12 levels.
- Kidney disease: Kidney disease can also lead to elevated B12 levels.
It’s essential to consult with a healthcare professional to determine the underlying cause of high B12 levels.
Are B12 injections for cancer patients?
Vitamin B12 injections may be recommended for cancer patients who have a deficiency or are at risk of deficiency due to their cancer treatment. B12 injections can help to:
- Boost energy levels: Cancer treatment can lead to fatigue, and B12 injections can help to increase energy levels.
- Support nerve function: B12 is essential for nerve function, and injections can help to support nerve health.
- Prevent deficiency: Cancer treatment can lead to B12 deficiency, and injections can help to prevent this.
However, B12 injections are not a treatment for cancer itself, and they should only be used under the guidance of a healthcare professional.
Can chemo cause B12 deficiency?
Yes, chemotherapy can cause vitamin B12 deficiency in some cases. Chemotherapy can damage the cells in the gut that produce intrinsic factor, a protein that helps the body absorb B12 from food. This can lead to B12 deficiency over time.
Additionally, some chemotherapy drugs can interfere with the body’s ability to absorb B12 from food, leading to deficiency.
Which cancer depletes B12?
Some types of cancer that can deplete vitamin B12 levels include:
- Colon cancer: Colon cancer can lead to B12 deficiency due to the cancer’s location in the gut, where B12 is absorbed.
- Stomach cancer: Stomach cancer can also lead to B12 deficiency due to the cancer’s location in the gut.
- Pancreatic cancer: Pancreatic cancer can lead to B12 deficiency due to the cancer’s impact on the pancreas, which produces digestive enzymes that help absorb B12.
Can B12 cause colon cancer?
There is no evidence to suggest that vitamin B12 causes colon cancer. However, some studies have suggested that high levels of B12 may be associated with an increased risk of colon cancer.
This association may be due to the fact that B12 can stimulate the growth of cancer cells, including colon cancer cells. However, more research is needed to fully understand the relationship between B12 and colon cancer.
It’s essential to note that B12 is an essential nutrient, and deficiencies can have serious health consequences. If you have concerns about B12 and colon cancer, it’s best to consult with a healthcare professional.
Can Vitamin B12 Deficiency Be a Sign of Cancer: Conclusion
While “can vitamin B12 deficiency be a sign of cancer?” is a question without a simple yes-or-no answer, we know it’s a potential warning sign worthy of attention. While there’s more to be uncovered in the relationship between this vitamin deficiency and certain types of cancer, understanding the role B12 plays in your body and responding proactively is important for good health overall.
