Breast milk may spread viruses that cause breast cancer

Breast milk and HPV

We all know that faulty genetics is partly responsible for breast cancer in a family members. But faulty genetics is not the sole danger element for breast cancer that spreads from a mother to her daughter(s).

Reports advise that viruses that lead to or improve threat of breast most cancers can unfold from 1 generation to yet another through breast milk.

Dr. W.K. Glenn and colleagues printed a research in BMC Investigation Notes that had located high danger human papillomavirus and Epstein Barr virus in human breast milk and babies drinking the virus-loaded milk may deal the cancer-leading to viruses.

The authors noted that numerous viruses such as human immunodeficiency virus (HIV), Epstein Barr virus (EBV) and mouse mammary tumour virus have presently been identified in human milk and substantial chance human papillomavirus (HPV) sequences have already been discovered in breast cancer tissue.

Seemingly, infant girls who drink milk from their infected moms may possibly get infected with the viruses. But the existing examine has located these viruses might also be existing in human milk from regular lactating girls who experienced no heritage of breast most cancers.

The researchers located high risk HPV in fifteen% of milk samples from standard lactating Australian women. 4 samples had been sequenced and HPV 16 was identified in three samples and HPV 18 was identified in one sample. Epstein Barr virus was detected in 33% of breast milk samples.

The researchers concluded "The existence of large chance HPV and EBV in human milk implies the possibility of milk transmission of these viruses. Nonetheless, provided the rarity of viral related malignancies in younger men and women, it is feasible but not likely, that this kind of transmission is associated with breast or other cancers."

Though HPV was located in non-cancerous tissue, HPV was also discovered in breast cancer tissue, suggesting that these viruses might engage in a role in the improvement of specified instances of breast most cancers.
