First off, let’s talk about nighttime light exposure. Studies have shown that women who work the night shift have a higher risk of breast cancer compared to those who don’t.

Other research has shown that high levels of external lights, such as street lights, influence a higher risk of breast cancer. Some experts believe this could be partly due to the suppression of melatonin, a hormone with powerful antioxidant activity. Even the slightest bit of light at nighttime, which can come from inside lights, as well as the light emitting from TVs and other screens such as tablets and cell phones.

Vitamin D has been shown to play a profound role as well. Women with low vitamin D levels have a higher risk of breast cancer. The belief is that vitamin D may play a role in controlling normal cell growth, while slowing, or stopping breast cancer cells from growing.

“Normal” vitamin D levels are between 30 ng/ml and 100 ng/ml. One study has shown that women with blood levels above 60 ng/ml had 20% the risk of breast cancer compared to those with levels at 20 ng/ml or less. This falls in line with an abundance of research showing the sweet spot for vitamin D levels to be between 60 ng/ml and 80 ng/ml.

Being overweight and/or the presence of the “muffin top” effect, can increase one’s chance for breast cancer quite dramatically. This should come as no surprise as estrogen is a hormone responsible for tissue growth.

Lastly, let’s talk about the B vitamins and methylation. A study from 2017, revealed a link between a higher intake of vitamin B6 and vitamin B1 and a lower risk of breast cancer. The same study also found a reduced risk of breast cancer in association with supplementation of vitamins B1, B2, B3, B5, B6, Folate and B12 among women with low or no alcohol intake.

Methylation plays a role in numerous areas of our body. Methylation, when done properly, assures the proper regulation of gene expression. If methylation is not given the opportunity to occur as it should, there can be a modification in gene expression which can promote the development of several cancers, including breast cancer.

B vitamins play a critical role in the proper expression of methylation, especially folate, B2, B6 and B 12.

When considering a B Complex, I recommend using the active, highly absorbable B vitamins such as folate, instead of folic acid, and methylcobalamin, over cyanocobalamin.

Therefore, we recommend B Complex Plus from Pure Encapsulations, which Martin’s Pharmacies carry behind the counter.
