Scientists have studied Bovine Leukemia Virus, informally known as BLV for quite a while. Investigators have studied the cellular structure of the virus, the hypothetical vaccine and the correlation with cow’s milk. However, recently a study done by researchers at the University of California Berkeley concludes that there is a link between the infection (BLV) and human breast cancer.
In a study published in PLOS ONE,the investigators take note of all of the potential causes of breast cancer. They extrapolate that the key reasons behind breast cancer are age, reproductive history, hormones and genetics. The researchers additionally detected that the Bovine Leukemia Virus was in the breast epithelium of humans. The objective of this experiment was to determine whether the presence of BLV DNA in human mammary epithelium is associated with breast cancer.
The researchers conducted a case study in which archival formalin-fixed paraffin embedded breast tissue was injected in the control group (women without history of breast cancer) and the experimental group (women with a history of breast cancer.) The rate of occurrence of BLV DNA from women with breast cancer was 59%, while the rate in the control group was a diminutive 29%.
This experiment has helped researchers conclude that the presence of amplified BLV DNA is significantly correlated with female breast cancer. The findings in this experiment and ones similar to it assist in conceptualizing a potential primary and secondary breast cancer prevention tactic.
