In Mexico only 10 percent of the cases of cancer in stage one, this is a tumor of less than two times. 75 percent of cases are discovered until the third stage, and the chances of total recovery from 85% in the first stage down to 35%.

Breast cancer is the most common cancer in women, both in countries and in developing countries. The incidence has been improving in the developing world due to longer life expectancy, increased urbanization, and the adoption of Western lifestyles.

Although there are several campaigns to prevent the disease, October 19 is about awareness of the importance of early detection. According to the World Health Organization (WHO), every 30 seconds somewhere in the world a breast cancer is diagnosed. In Mexico it is the second cause of mortality in women between 20 and 59 years. The state of Jalisco occupies the fourth national place in mortality from this condition.

The early detection strategies recommended by the World Health Organization for low-income and media countries are awareness of the first signs and symptoms plus clinical breast examination.

Although the campaigns emphasize self-exploration, this is not enough. It is essential for women aged 40 or over for one woman a year and for those under 40 years of age.
