Lower the cervical cancer smear test age to 18

So many young women and girls have unfortunately lost their lives to this silent killer all because cases of cervical cancer are considered less likely in women under 25 and are more likely to test and that only 65 out 3000 cases diagnosed are under 25 but they are still cases none the less. Surely the unfortunate deaths of previous young women considered 'underage' have not died in vain. Women's rights have come along way but why isn't this a given right for young women everywhere?
