Abstract
Cancer has increased in all the countries of the world and Mexico is no exception. The recognised risk factors for the main types of cancer are reviewed and searched through the Mexican government web pages and cancer prevention programmes to tackle the risk factors in the population. The Mexican government, a member of the World Health Organization, shows that the main approach is an early diagnosis rather than prevention, forgetting that an ounce of prevention is better than a pound of cure. Effective public programmes should be promoted to reduce preventable risk factors in the population (smoking, nutrition, obesity, diet, environmental toxicity, sedentary lifestyle) and control the non-preventable factors (genetics) if we really want to control the incidence of different types of cancer.
Highlights
Cancer is a generic term that covers a group of illnesses characterised by the increase of abnormal cells that can invade adjacent body parts and spread to other organs [1]
In the scientific literature and in the political discourses on health much is spoken of prevention, the reality is that the evidence shows weakness in Mexico and in many countries about the programmes designed for the prevention of cancer
Decision-makers should focus on more successful cancer prevention programmes in the areas outlined by the World Health Organization (WHO): smoking, obesity, nutrition, food, environmental toxins, genetic detection of cancer-promoting genes, increasing physical activity; if the population acquired a healthy lifestyle in these areas, the frequency of cancer would fall
Summary
It is important to note that, it has been shown in studies with cell cultures and in laboratory animals that some food additives and preservatives can be mutagenic and carcinogenic at certain concentrations and at different exposure times, there is no conclusive scientific evidence showing that this effect is seen in human beings exposed daily or occasionally to the concentrations that are present in this type of food [94, 95, 2, 3] This is probably why they continue to be significantly produced, distributed and consumed in developed and developing countries. There are only official Mexican standards to minimise the emission of pollutants and exposure to the environmental toxins mentioned [105, 131,132,133,134, 13, 39,40,41,42]
