Four hundred scientists from around the world are in Lausanne to discuss the latest developments in cancer research. They are attending a symposium of the Swiss Institute for Experimental Cancer Research, or ISREC.
The symposium, entitled "Cancer and the Cell Cycle", is one of the most important in that field of research this year. The discussions will focus on defects in regulation of cell division.
The meeting also offers a platform for young Swiss researchers to establish contacts with the world's leading specialists.
Richard Iggo, a senior scientist at ISREC, told Swissinfo that new treatments are being developed. "There are some viruses that have been developed which will target cells with defects in regulation of the cell cycle."
Iggo also describes another potential treatment, using replicating viruses. "These viruses replicate only in tumour cells, so the idea is to inject small amounts of virus into the tumour, and then the cancerous cells do the work."
Some of these viruses have already been successfully tested on patients.
The conference is due to end on Monday.
