Despite their large bodies and long lifespans (寿命), elephants are much less likely to die from cancer than humans, with death rates of less than 5 per cent. The paradox has puzzled scientists because more cells leads to greater replications, which increases the possibility of the body failing to detect damaged DNA or a faulty cell that can result in tumours (肿瘤). Elephants live for almost as long as humans, and can weigh up to five tons. However, a group of British and European scientists say they have taken a big step towards solving Peto’s paradox, named after the British epidemiologist Sir Richard Peto. Elephants, they say, carry a much larger, more diverse group of tumour-fighting proteins. The findings, published last week in the journal Molecular Biology and Evolution, raise hopes that the cancer-fighting genes in elephants could be the key to tackling cancer, which kills about 167,000 Britons each year. Cells keep dividing throughout an organism’s life, each carrying the risk of producing a tumour. One of the body’s weapons is a gene called p53, known as the “guardian of the genome”, which hunts cells with faulty DNA．It encourages the cell to repair itself or self-destruct, keeping the cell from binding with others and producing tumours. Humans have tw
