Bovine leukosis B-cell leukemialymphoma first described in 1871 in Lithuania was believed to be an infectious disease because it spread through herds of cattle.

Women who are infected with a virus called the bovine leukemia virus BLV may face an increased risk of breast cancer according to a recent study. New data on the link between a viral agent and breast cancer in women was recently published and indicated that an animal virus the bovine leukemia virus BLV might be possibly associated with. One other study found evidence of BLV in samples from a specific type of lung cancer.

Bovine Leukemia Virus as a Cause of Breast Cancer Michael Greger MD. UC Berkeley researchers have linked bovine leukemia virus a cancer-causing virus prevalent in cattle with human breast cancer. As many as 37 of breast cancer cases may be attributable to BLV exposure. BLV belongs to the Retroviridae family.

We previously detected bovine leukemia virus BLV a common oncogenic virus of cattle in the breast epithelium of humans. It has prompted much interest as an anticancer agent because it can replicate up to 10000 times better in human cancer cells than in most normal cells. Researchers found that 80 percent of cases of squamous cell carcinoma of the lungs were infected with BLV. Bovine Leukimia Virus has probable risk to animals and human health.

New data on the link between a viral agent and breast cancer in women was recently published and indicated that an animal virus the bovine leukemia virus BLV might be possibly associated with the etiopathogenesis of breast cancer9. The presence of bovine leukemia virus DNA in breast tissues was strongly associated with diagnosed and confirmed breast cancer. Despite numerous publications23 to the best of our knowledge there is as yet no consensus regarding a viral role in either the.

Introduction Bovine leukemia virus BLV is a delta retrovirus most similar to human T-cell lymphotropic virus 1 HTLV-1.

Evidence of the presence of bovine leukemia virus BLV in human beings and its association with breast cancer has been published in the literature proposing it as a zoonotic infection. The virus is further classified in Orthoretrovirinae subfamily and deltaretrovirus genus which is considered as a possible zoonotic infection 9. Bovine leukemia virus BLV and human papillomavirus HPV were previously identified in human breast tissue and have been associated with breast cancer in independent studies. Bovine leukemia virus BLV and human papillomavirus HPV were previously identified in human breast tissue and have been associated.

Recently BLV has been identified in human breast cancers giving rise to the hypothesis that it could be one of the causative agents of this condition. As many as 37 of human breast cancer cases may be attributable to exposure to bovine leukemia virus. The link between bovine leukemia virus infection and breast cancer remains somewhat murky. Bovine leukemia virus BLV a common virus of cattle globally was believed for decades not to infect humans.

The objective of this study was to determine whether the presence of BLV DNA in human mammary epithelium is associated with breast cancer. In the study researchers tested the breast.
