CAIRO (AFP) - There is no "scientific" proof to back claims by Hosni Mubarak's lawyer that the ousted president has cancer, an Egyptian health ministry official said in statements published on Sunday. Mubarak has "a stomach cancer and the tumours are growing," his lawyer Farid al-Dib told AFP on Monday. "The health ministry does not have a single scientific document saying that Mubarak has cancer," Abdelhamid Abaza, an assistant to the health minister, was quoted as saying by Al-Ahram and Al-Masry Al-Youm newspapers.
