A new panel of genes could pick out men at highest risk of developing prostate cancer and pick out those already diagnosed who are likely to have particularly aggressive forms of the disease, a large-scale genetic analysis has found.

A ring of proteins that holds our chromosomes together as they replicate also plays a vital role in stopping DNA damage from leading to cancer, according to new research.

Testicular cancer in families is usually caused by the accumulation of minor genetic changes that have only a small effect on their own, but together can add up to a significant risk.
