Some more positive health news; this research sounds very hopeful for limiting the spread of cancer in the future.
The deadly spread of cancer around the body has been cut by three-quarters in animal experiments, say scientists. Tumours can "seed" themselves elsewhere in the body and this process is behind 90% of cancer deaths. The mouse study, published in Nature, showed altering the immune system slowed the spread of skin cancers to the lungs. Cancer Research UK said the early work gave new insight into how tumours spread and may lead to new treatments. The spread of cancer - known as metastasis - is a fight between a rapidly mutating cancer and the rest of the body.
