Scientists are claiming the world’s second-leading cause of death may soon be history. Cancer researchers in Israel have announced they expect to cure cancer within the year. Dr. Ilan Morad tells the Jerusalem Post a new treatment called MuTaTo uses “cancer-targeting peptides for each cancer cell at the same time combined with a strong peptide toxin that would kill cancer cells specifically.” He says the treatment will require just one dose to completely rid a patient of cancer.

Critics aren’t so sure. The Daily Mail points out that the researchers’ study was only performed in mice and human trials would take years to initiate and complete. Beyond that, with all the different types of cancers, critics say it’s unlikely that one cure will be able to wipe them all out.
