WEIGHT LOSS AND CANCER
Many people do not know that weight gain and obesity are associated with many types of cancer. Among the most common types of cancer that are markedly increased in their incidence in overweight and obese people are breast cancer, colorectal cancer uterine cancer and ovarian cancer. Usually the risks for each of these types of malignancy more than doubles when a person’s body mass index exceeds 40. Numerous studies have confirmed these worrisome findings.
Less well proven is that weight loss can reduce the risk of cancer, but there are many studies that give us some encouraging evidence that this phenomenon does indeed occur. Among the studies are those by Flynn and many others that have demonstrated a reduction in cancer risks after successful weight loss surgery. In a large population based study, these researchers have demonstrated a reduced risk of these same cancers in the years following weight loss surgery.
We know that weight gain and obesity markedly increase the cancer risk for human beings. We know that in weight loss surgery studies this cancer risk subsequently declines. We hope that research will also demonstrate that successful weight loss with medically based programs, such as the iMetabolic program, also result in a drop in cancer risk, but those long term studies are not yet available. What is know is that cancer is yet another very compelling consideration and a powerful, motivating tool we should all take advantage of to help encourage long term weight reduction and maintenance of a healthy weight.
