Can Vitamin B12 Deficiency Be a Sign of Cancer?

Introduction
Vitamin B12 helps your body make red blood cells and keeps nerves healthy. It also supports your brain, heart, DNA, and overall growth. When vitamin B12 levels drop, symptoms such as tiredness, numbness, and memory issues become too familiar and easy to overlook. However, the question is, can vitamin B12 deficiency be a sign of cancer? Many don’t realize that Vitamin B12 deficiency can sometimes indicate a bigger problem.
What’s worrying is that these symptoms often look like early signs of cancer. If you ignore them, you might delay getting the proper diagnosis and treatment.
Does Vitamin B12 Deficiency Indicate Cancer?
Vitamin B12 deficiency doesn’t directly cause cancer, but it can sometimes indicate other health problems that increase cancer risk. For example:
Pernicious Anemia: It prevents your body from absorbing Vitamin B12 and can raise the risk of stomach cancer.
Cancer Treatments: Chemotherapy or radiation can make it harder for your body to absorb nutrients, leading to Vitamin B12 deficiency.
Researchers are still looking for the links between B12 deficiency and cancer, but some studies show a link between low B12 levels and a higher risk of certain cancers.
Cancers Linked With Vitamin B12 Deficiency
Stomach or Gastric Cancers
B12 deficiency can be a sign of health problems, like atrophic gastritis, pernicious anemia, or an infection with Helicobacter pylori, which can damage the stomach lining.
This damage can make it harder to absorb B12 and may increase the risk of stomach cancer over time. So, while B12 deficiency can point to underlying stomach problems that raise cancer risk, it’s not the direct cause of this cancer.
Blood Cancers
Lower Vitamin B12 levels can also indicate blood cancers, such as leukemia. Blood cancers harm the bone marrow, making producing healthy red blood cells challenging, thus lowering vitamin B12 levels in the body.
Studies also suggest that chemotherapy drugs like imatinib, often used to treat blood cancers, can lower Vitamin B12 levels by reducing nutrient absorption.
Cervical Cancer
Low vitamin B12 can indicate cervical cancer as B12 is linked to a grown risk of HPV (Human Papillomavirus) infections, which are responsible for such cancer cases. Thus, ensuring your body has enough B12 may help lower this risk and strengthen your immune system.
Other Causes for Vitamin B12 Deficiency
Vitamin B12 deficiency happens when digestive problems, surgeries, or too much alcohol stop the body from absorbing it. Pregnant women, older adults, and people with poor diets are more likely to have low B12 levels.
- Issues like Crohn’s disease, celiac disease, or gastritis damage the stomach or intestines, making it hard to absorb B12.
- Surgeries like gastric bypass or removing part of the intestine reduce B12 absorption.
- Drinking too much alcohol damages the stomach lining and stops the body from absorbing enough B12.
- Old age can also be a factor, as people with this condition produce less stomach acid, which is essential for absorbing Vitamin B12.
- Pregnant or breastfeeding women may not get enough B12 because their bodies need more to support the baby.
- Eating an unhealthy diet for a long time can cause low B12 levels, especially for vegans and vegetarians, as it’s primarily found in meat, fish, eggs, and dairy.

Conclusion
Vitamin B12 deficiency doesn’t always mean cancer, but it can signal health problems that might increase cancer risks. You can reduce such risks and improve your overall health by staying alert to symptoms, testing your B12 levels, and maintaining a healthy diet.
The two leading causes of B12 deficiency are a poor diet and problems absorbing B12. People who don’t eat animal products, like vegans, often lack B12. Conditions like pernicious anemia or Crohn’s disease can also block absorption and cause deficiency.
B12 deficiency starts with low levels in the blood and then affects the cells. The third stage shows symptoms like anemia and tiredness. The fourth stage causes severe problems like nerve damage and memory loss.
Signs of B12 deficiency include feeling very tired, numbness or tingling in your hands and feet, and pale or yellow skin. You might also have a swollen tongue, mouth sores, dizziness, or a fast or irregular heartbeat.
B12 deficiency mainly affects your brain and nerves, causing nerve damage and memory problems. It also impacts your bone marrow and heart, leading to anemia and poor oxygen supply. Early treatment can prevent permanent damage.
