translated from Spanish: Scientists develop viruses to cure cancer

Usa.- Various cancers have been successfully attacked and fought with a new treatment created from a virus derived from bovine smallpox. The studies were conducted by American scientists and successfully tested in mice, by next year it is expected to start testing the treatment in humans, however, its mass use as treatments in humans could be delayed a few years. 

The virus called CF33 was used in cell therapy with cancer by a group of scientists led by Yuman Fong, the virus attacks cancer cells and causes them to explode, and would cause humans’ immune system to identify tumors carcinogenic and attack them on its own. 
Human testing with this virus would begin in 2020 and be injected directly into the tumor of patients with breast cancer, melanoma, liver, bladder, gastric and intestinal cancer. 

If successful, the treatment would begin to be developed by an Australian biotechnology company, however, specialists indicate that successful results in mice may not replicate in humans because the immune system could detect remove it from the system before it destroys the carcinogenic tumor. The specialist noted that similar tests have already been done with other viruses to treat brain cancer with the cold virus, and for melanoma by modifying the herpes virus. The professor explained that the virus to create CF33 was not chosen at random but is an investigation carried out since 1992 when doctors noticed a strange feature: people who received the rabies vaccine, made on the basis of the causative agent of the vaccine, the growth of the tumors decreased.
