Women Are Less Likely to Develop Cancer Due to Protective Genes
A new research, published in Nature Genetics, finds that women are less likely to develop cancer than men because they may be programmed to resist the disease. Scientists say they carry an extra copy of certain protective genes in their cells.
For their study, the researchers scanned the genomes of more than 4,000 tumour samples of 21 different types of cancer. Then they examined whether any of the irregularities were more common in male cells or female cells. The result is that of 800 genes found solely on the X chromosome, 6 were more frequently mutated and incapacitated in males than in women.
Dr Andrew Lane from the Dana-Farber Cancer Institute, Boston, USA, says: “Across virtually every type of cancer, occurrence rates are higher in males than in females.”
