Vaccination key to combat cervical cancer

Vaccination key to combat cervical cancerNew York, Dec 26 - Cervical cancer is the second most common cancer in women and is responsible for nearly 10 percent of cancer deaths in women - particularly in developing countries. In India, it kills over 74,000 women every year.

Now, researchers have completed a systematic and comprehensive genomic analysis of cervical cancer in two different populations - identifying recurrent genetic mutations that were not previously found in cervical cancer.

The findings also capture the role that human papillomavirus (HPV), a common viral infection of the reproductive tract, plays in the development of cervical cancer.
