Although the reason is not known exactly, certain prevalences have been detected in Mexico and Latin America that may influence:
1. The population pyramid is different. In other words, there are more young women in Mexico than in other parts of the world.
2. Lifestyles Not 100% tested, but there are certain factors to consider:
• Obesity, is not just a predisposition for mom’s cancer but for many others. About 70% of women in Mexico are overweight and obese, which increases the chances of starting an accelerated growth of breast tissue and that allows certain mutations to occur that lead to cancer. They are also prone to generate more estrogens and this conditions the aforementioned breast growth.
• Reproductive patterns, patterns from developed countries are being adopted, such as having the first child at an older age, having few children and even not having them. Dr. Cynthia Villarreal, director of Clinical Oncology at the TecSalud Breast Cancer Center, explains that the earlier menstruation occurs, the later menopause or the longer the period is, the more likely it is that the breast cells they are exposed to more estrogens and therefore to a greater proliferation of the breast tissue that leads to a greater mutation.
• Hormones, especially if they are used for more than five years. Hormones promote the development of estrogen and, as we said previously, there is a greater proliferation of breast tissue.
• Tobacco, according to studies done in the United States, women smokers tend to consume alcohol and have fewer mammograms, making it more difficult to campaign preventively with them.
3. Low rate of timely detection: In Mexico few women do preventive mammograms, in other countries 70 or 80% of women do them, that allows greater control and that any suspicious tumor can be detected in time, before make it carcinogenic. In our country, normally when the tumor is detected it is already carcinogenic and unfortunately most of the time in a very advanced state.
4. Genetic component is still being studied, but it is believed that we have a genetic component that predisposes more to breast cancer at younger ages. The younger a woman gets cancer, the more likely it is due to a genetic factor. In those under 40 there is a 15% probability that it is due to a secondary genetic factor.
If in your family there is a history of breast cancer or in your lifestyle there are risk factors that we mention we recommend:
• Self-Exam The American Cancer Society recommends a monthly breast self-exam for all women age 20 and older.
• Clinical examination from the age of 25 with a doctor who has knowledge in the exploration of mothers and should be done annually.
• See an oncologist if you have any suspicion due to a change in the breast or a clinical examination.
