The bariatric surgery is a medical intervention designed to help people with severe obesity lose weight and improve their overall health. In recent years, studies have shown that this surgery not only helps reduce body weight, but can also have a significant impact on the risk of developing certain types of cancer.
What is Bariatric Surgery?
The bariatric surgeryalso known as weight loss surgery, includes a variety of procedures that alter the digestive system to help people lose weight. Among the most common techniques are gastric bypass, sleeve gastrectomy and adjustable gastric banding. These procedures have proven effective in the treatment of obesity and related diseases.
Cancer Risk Reduction
The relationship between the bariatric surgery and cancer risk reduction has been the subject of numerous studies over the past decade. Results indicate that people who undergo weight loss procedures experience a significant decrease in the incidence of several types of cancer.
One of the proposed mechanisms for this reduction is the reduction of adipose tissue. Obesity is associated with elevated levels of chronic inflammation, which is a known risk factor for the development of cancer. By reducing the amount of adipose tissue, the bariatric surgery decreases systemic inflammation, which in turn reduces the risk of malignant cell transformation.
In addition, post-surgical weight loss improves the patient's hormonal profile. For example, a decrease in insulin and insulin-like growth factor (IGF) levels, both of which are linked to cell proliferation and cancer, has been observed. Decreased estrogen levels, especially in postmenopausal women, also contribute to a reduced risk of breast and other hormone-dependent cancers.
Another important aspect is the improvement in mobility and overall quality of life. Reduced body weight allows patients to adopt more active and healthy lifestyles, which is associated with a lower incidence of cancer. The ability to participate in regular physical activity and adopt a balanced and nutritious diet after the bariatric surgery plays a crucial role in long-term cancer prevention.
Scientific Evidence
The evidence base that supports the relationship between the bariatric surgery and cancer risk reduction is robust and growing. Numerous epidemiological and clinical studies have shown that patients who undergo weight loss procedures have a significantly lower risk of developing several types of cancer compared to those who do not undergo surgery.
A study published in The Lancet Oncology found that bariatric patients had a 33% reduction in overall cancer risk. This study, which included more than 10,000 patients, showed that long-term weight reduction was directly related to a lower incidence of breast, colon, endometrial, and pancreatic cancers.
Another important study published in JAMA Surgery analyzed data from more than 22,000 patients and discovered that the bariatric surgery was associated with a 40% decrease in cancer risk compared to non-surgical controls. This study also indicated that the greatest reduction in risk was seen in the first five years after surgery, highlighting the importance of sustained weight loss.
In addition, research conducted by the American Society for Metabolic and Bariatric Surgery (ASMBS) have shown that the bariatric surgery not only reduces the risk of cancer, but also improves survival rates in patients who have already been diagnosed with cancer. Weight loss and improved metabolic health contribute to a better response to cancer treatments and improved long-term survival.
The evidence also suggests that the benefits of bariatric surgery extend beyond weight reduction. Surgery-induced metabolic changes, such as improved insulin sensitivity and reduced chronic inflammation, play a crucial role in decreasing cancer risk. These findings underscore the importance of considering the bariatric surgery not only as an obesity intervention, but also as a comprehensive cancer preventive strategy.
The Role of Dr. Luis Cano in Bariatric Surgery
The Dr. Luis Canoa renowned specialist in bariatric surgeryhas been a pioneer in this field, standing out not only for his surgical skills but also for his comprehensive approach to the treatment of obesity. His practice, Obesity Outlocated in Tijuana, Mexicohas helped countless patients improve their health and reduce their risk of chronic diseases, including cancer.
Patient Testimonials
Many patients who have undergone bariatric procedures have reported not only a significant improvement in their weight and overall health, but also a decrease in their concerns about cancer. These testimonials underscore the importance of considering the bariatric surgery not only as a solution for obesity, but also as a preventive measure against cancer.
Considerations and Risks
Although the bariatric surgery offers multiple benefits, it is not without risks. It is crucial that patients are thoroughly evaluated and provided with complete information about potential risks and complications. Proper patient selection and postoperative follow-up are essential to maximize benefits and minimize risks.
Conclusions
The bariatric surgery represents a powerful tool in the fight against obesity and its related complications, including cancer. With professionals such as Dr. Luis Cano and specialized centers such as Obesity Out in Tijuana, Mexicopatients have access to high-quality treatments that can significantly improve their quality of life and reduce their long-term health risks.
