Recent researches targeting prostate cancer have associated the prostate cancer development with the presence of a newly identified virus called XMRAV. According to study conclusion the XMRV was identified as an infectious agent in humans and closely related to a virus that causes leukemia in mice.
The findings are based of screening prostate tumor samples from 85 men with prostatectomy with a DNA ViroChip containing the genetic sequences of about 5,000 human viruses. The researches confirmed the possibility that a viral infection might lead to prostate cancer developing in men.
XMRV could be transmitted trough sexual activity. Then it is possible that XMRV to cause an infection able to lead to chronic inflammation of the prostate. In a way similar human papillomavirus (HPV) can trigger cervical cancer, this chronic inflammation caused by XMRV could result in prostate cancer.
This could be the first time an evidence is produced that a virus is related to prostate cancer development.
The research team conclusion suggests that more research is needed to confirm their findings. The good news seems to be the fact that if prostate cancer is caused by a virus such as XMRV, then its action can be cancelled using special targeted drugs or vaccine. The use of condom could be also a way to prevent XMRV sexual transmission. |
