All Autonomous Communities (AC) have well established population screening programmes for early detection of breast cancer, which include carrying out a mammography, and some have already covered all the women in the target population. The early detection programmes for cervix cancer are established to a larger or lesser extent in certain AC and perform Papanicolaous test. Most are opportunistic screening and usually include primary care equipment for their development. More than half of Spanish women aged 40 to 70 had had at least one mammography in the last two years, and in most cases they had done it for preventive reasons. Women aged 51 to 60 are the women who, with more frequency, had received the mammogram. Likewise, just over half the women had had a Papanicolaou cytology in the last three years, and in most cases it was also for preventive reasons. More young women then older women have the cytology done. We believe it would be interesting to learn about the factors related to the use of mammography and Papanicolaous test in Spain.
