What is cancer?
Cancer refers to a group of diseases characterized by uncontrolled growth of abnormal cells that can invade tissues and spread to other parts of the body. There are more than 200 types of cancer, each with specific causes, biological mechanisms, and treatments. A better understanding of these mechanisms is essential to improve prevention, diagnosis, and care.
Cancer research: where do we stand?
Recent scientific advances have profoundly changed our understanding of cancer.
How does cancer develop?
- Step 1: Cellular alterations
Genetic mutations or epigenetic modifications disrupt the normal functioning of cells.
- Step 2: Uncontrolled proliferation
Abnormal cells multiply without control and escape the body’s natural regulatory mechanisms.
- Step 3: Invasion and metastasis
Some cancer cells can invade nearby tissues or spread to distant sites via the blood or lymphatic system.
Cancer risk factors
What are the main risk factors?
Genetic and hereditary factors
Tobacco use and exposure to tobacco smoke
Unbalanced diet and physical inactivity
Exposure to chemical agents or radiation
Viral infections (HPV, hepatitis viruses, EBV)
Aging and weakened immune system
The presence of one or more risk factors does not necessarily mean cancer will develop, but it increases the likelihood.
The importance of early detection
Why detect cancer as early as possible?
Early detection allows identification of certain cancers at a stage when treatments are more effective and less burdensome. Many screening programs have shown a positive impact on reducing mortality, notably for breast, cervical, and colorectal cancers.
Human impact and support
Cancer: a fundamentally human reality
Beyond scientific data, cancer profoundly affects patients, their families, and caregivers. Information, psychological support, and social assistance play an essential role throughout the care pathway.
Cancer and genetics
Genes play a central role in normal cell function. When certain mutations occur, they can disrupt cellular control mechanisms and promote cancer development. In some cases, these mutations are hereditary, but more often they appear during life as a result of environmental factors or aging.
Epigenetics and cancer
Epigenetics studies reversible modifications of gene expression that do not change the DNA sequence. These modifications can be influenced by diet, stress, exposure to toxins, or lifestyle. In oncology, epigenetics helps explain why some cells become cancerous and opens new paths for prevention and early detection.
Breast Cancer: Strength, Hope, and Shared Journeys
Women and Breast Cancer: Stories of Courage
-
Breast cancer affects millions of women worldwide, yet behind every diagnosis is a story of courage, resilience, and determination. Women facing breast cancer often endure physically and emotionally demanding treatments, including surgery, chemotherapy, radiation, and long periods of uncertainty. Despite these challenges, many continue to show extraordinary strength not because they chose the fight, but because they refuse to give up.
- Breast cancer survivors and patients are not defined by their illness. They are mothers, daughters, professionals, creators, and leaders who demonstrate daily what it means to persevere in the face of adversity.

- “Women who fight cancer show a strength that goes far beyond the disease itself.”
Living Through Treatment: More Than a Medical Journey
- Breast cancer treatment is not only a medical process it is a deeply human experience. Hospital stays, treatment side effects, and moments of physical weakness are often accompanied by fear, hope, exhaustion, and determination. Many patients describe their journey as both painful and transformative, filled with setbacks but also moments of clarity, gratitude, and personal growth.

- Understanding this reality is essential to supporting patients with empathy, accurate information, and respect for their individual experiences.
Breast Cancer as a Shared Human Experience
Breast cancer is not only a medical condition; it is a shared human experience shaped by personal stories, family bonds, and community support. Every voice that speaks openly about breast cancer contributes to greater awareness, understanding, and hope.
Education, compassion, and connection remain among the most powerful tools in the fight against breast cancer.
Frequently Asked Questions
No. The majority of cancers are not hereditary but result from a combination of environmental and biological factors.
No. Many cancers can be cured or controlled over the long term, especially when they are detected early.
Stress alone is not a direct cause, but it can influence risky behaviors and overall health.
