For the past 30 years, the relationship between obesity and certain cancers has been growing. At least 13 types of cancer are linked to obesity in humans, including colorectal and stomach cancer, uterine, breast, ovarian and endometrial cancer in postmenopausal women, kidney, esophageal, pancreatic, thyroid and multiple myeloma. The National Cancer Institute estimates that obesity and physical inactivity may account for 25 to 30 percent of major cancers. Animal models used in cancer research and current evidence suggest dogs and cats with obesity may also be at greater risk for developing cancer.
The debate on the fat-cancer link centers on whether excess fat cells primarily promote cancer or if the obesity-related insulin- resistance is to blame. Estrogens and estrogenlike compounds, insulin and growth factors, and chronic inflammation caused by excess fat all are proven ways obesity leads to cancer. The bottom line is that obesity causes increased cancer rates, certainly in mice and men; we just don’t understand exactly how.
This is a major reason to get you and your pet moving on a daily basis! We must change our lifestyles to include daily exercise! Not every other day, but daily! There are so many tasks that our grandparents did that we no longer have to do that gave them that daily activity. Our ancestors died of infections and diseases like measles, mumps and polio; we will die of inactivity!
