Mexico City; February 4, 2026.— Every February 4, we observe World Cancer Day, a day that invites us to reflect on one of the leading causes of illness and death worldwide, but also to discuss prevention, early detection, and hope. In Mexico, cancer is a serious public health problem.
Cancer in Mexico: A Public Health Challenge
It is currently the third leading cause of death in the country, with more than 90,000 deaths each year and an estimated 200,000 new cases annually. Among the most common types are breast, prostate, and colorectal cancers, all of which have a significant impact on the quality of life of patients and their families.
But what is cancer?
Cancer is not a single disease, but rather a group of conditions characterized by the uncontrolled growth of abnormal cells that can form malignant tumors and invade other tissues in the body. Although it may sometimes seem that little can be done in the face of this diagnosis, the evidence is clear: a significant proportion of cases can be prevented, and many others can be detected early, which radically changes the prognosis.
Cancer Prevention: The Role of Lifestyle
Today we know that lifestyle plays a key role. There are at least 13 types of cancer associated with obesity, 9 related to alcohol consumption, and 12 linked to tobacco use. Maintaining a healthy weight, avoiding cigarettes, and moderating alcohol consumption are not just general recommendations—they are concrete preventive measures.
Early detection is another fundamental pillar. Undergoing screenings in a timely manner can make the difference between simpler treatment and better long-term outcomes. Some general recommendations include Pap tests for women, mammograms starting at age 40, prostate-specific antigen (PSA) testing for men starting at age 50, and colonoscopies starting at age 45, according to the most recent guidelines. If you have a family history of cancer, it’s important to consult directly with your doctor to tailor your screening plan to your individual needs.
Research and Scientific Advances: Reasons for Hope
Despite the impact of cancer, there are also reasons for hope. Medical research is advancing every day. Recently, scientists in Spain achieved promising results in pancreatic cancer by developing a combination therapy that completely and permanently eliminated tumors in experimental models, without any significant side effects. Advances like these reinforce the message that science continues to open up new possibilities.
Taking care of your health doesn’t have to be extreme or prohibitive. An anti-inflammatory diet can be based on an 80–20 balance, prioritizing natural foods such as vegetables, fruits, lean proteins, whole grains, and healthy fats, and cutting back on ultra-processed foods, added sugars, and alcohol. This is complemented by regular physical activity, weight management, and medical checkups.
A Key Message on World Cancer Day
On this World Cancer Day, the message is clear: prevention starts today. Small, sustained changes over time can lead to big results. Making informed decisions is a powerful way to take care of our health and our future.
