A group of researchers from the University of NSW has become concerned as it has discovered that prostate tumours may sometime down the road be seen to be expanding, according to a report.

Two viruses found linked to the cancer have worried them as it is appearing that they may collaborate at any time, thereby worsening the present scenario. Not only will they give a boost to the survival of cancerous cells, the report says, but would also help them produce more and easily.

Human papilloma virus (HPV) has been seen to be present in almost 70% of the total number of prostate cancer samples. The statement is based on evidence found in a survey of both HPV and EBV (Epstein Barr virus). It has also been told that 55% of samples contained the EBV.

Since the strain of the HPV i. e. HPV 18 has been found to be highly risky as well as largely spread, health experts are urging everyone, particularly young girls at schools, to get a free vaccine against the same. Also, the vaccine is being extended to boys of the same age.

However, the university's School of Biotechnology and Biomolecular Sciences' Professor Whitaker says that the findings have a positive aspect too as the cancer would now be properly understood, thus leading to prevention techniques.
