Reducing Your Cancer Risk: Insights from Oncologist Dr. Ivan Pourmir

In 2023, cancer surpassed cardiovascular diseases as the leading cause of death in France. With over 400,000 latest cases diagnosed annually and nearly 4 million people currently living with the disease, understanding preventative measures is crucial. Dr. Ivan Pourmir, a medical oncologist and researcher at Georges-Pompidou Hospital in Paris, shares his insights on minimizing cancer risk.

The Role of Genetics in Cancer Development

Dr. Pourmir emphasizes that some cancers have a genetic basis. “Some cancers are explained by hereditary factors, and unfortunately, it is impossible to act on them,” he explains. Individuals with such genetic predispositions have an increased risk, but early detection through appropriate monitoring can significantly improve outcomes. In specific cases, like those carrying the BRCA 1 or 2 gene mutations, preventative surgery, such as prophylactic mastectomy – as seen with Angelina Jolie and Alice Detollenaere – can substantially reduce risk.

Environmental Factors and Cancer Risk

Beyond genetics, environmental factors play a significant role. Dr. Pourmir notes that these factors can vary depending on occupation and exposure to carcinogens. “There are many of them, and you can be exposed to them depending on your job,” he states, referencing his own research involving carcinogenic chemicals and the necessity of adequate protection when handling them.

Dr. Pourmir’s Daily Habits for Cancer Prevention

What steps does Dr. Pourmir take in his own life to mitigate cancer risk? He highlights several key habits:

• Limit Alcohol Consumption: Following recommendations, he suggests limiting intake to one drink per day for women and two for men, and not daily.
• Regular Exercise: Dr. Pourmir prioritizes regular physical activity, emphasizing its benefits for overall health, though acknowledging the current level of evidence is lower than for factors like smoking.
• Organic Diet: He favors organic produce, particularly fruits and wheat products, to minimize exposure to pesticides like glyphosate. He stresses the importance of balance and affordability, suggesting prioritizing organic options where feasible.
• Sun Protection: Dr. Pourmir avoids excessive sun exposure, preferring to forgo sunscreen. He recommends avoiding the hottest hours of the day and using SPF 50 sunscreen when sun exposure is unavoidable.
• Healthy Lifestyle: Recognizing the complex interplay between the nervous system, psyche, and immune system, Dr. Pourmir acknowledges the potential impact of these factors on cancer development. However, he cautions against simply telling people to “not stress,” as this can be counterproductive.

The Importance of a Holistic Approach

Dr. Pourmir’s advice underscores the importance of a multifaceted approach to cancer prevention, encompassing genetic awareness, environmental awareness, and lifestyle choices. While some risks are unavoidable, proactive steps can significantly reduce the likelihood of developing this complex disease.
