SAO PAULO (AFP) - It may be one of nature's repulsive little blood-sucking parasites, but the humble tick could yield a future cure for cancers of the skin, liver and pancreas, Brazilian researchers have discovered. Producing a medicine from the find, though, will require years of clinical tests and a significant financial investment. "This is a radical innovation," said Ana Marisa Chudzinski-Tavassi, the molecular biologist at the Instituto Butantan in Sao Paulo who is leading the research. "To discover this is one thing. To turn it into a medicine is a whole other thing entirely," she said.
