15 things cancer doctors do to avoid cancer

“Eating too much sugar and junk food can cause fat to build up in your liver, which can cause liver damage and increase the risk of liver cancer. It has been predicted that this non-alcoholic fatty liver disease will be the leading cause of liver cancer and the rate of liver cancer will increase significantly in a few years.” —Dr Homayoon Sanati, breast cancer specialist

“Your immune system needs to be in optimal condition to seek out and destroy cancer cells. Having a calm lifestyle will promote a stronger immune system. If your body is not preoccupied with the physical and emotional effects of life’s little battles, your immune system can better focus on healing and protecting you. One thing I practise and highly recommend is controlling your stress level, especially about things that are out of your control. There will always be legitimate reasons to be worrisome or angry. But if your anxiety will not fix the situation, then accept, adapt and resolve things the best way you can.” —Amy Lee, PhD, associate director for research and chair in basic science in cancer research at USC’s Norris Comprehensive Cancer Center

“It’s important to be proactive regarding surveillance for cancer. Many are curable or have a better outcome when caught early. In addition, do regular examinations on yourself at home and get to know your own body well. Any concerns? Bring them up with your doctor at your next check-up.” —Dr Justin Piasecki, skin cancer surgeon

“Obesity and overweight have been linked with many types of cancers. To make sure my weight stays under control, I prioritise exercise, get enough sleep, choose foods low in carcinogens, and balance family and work. I also get early detection screenings. These are things everyone can do because, at the end of the day, even though we are experts we are no different from you!” —Dr Peter Shields, cancer prevention researcher and lung oncologist 

“Reconnecting with nature is an effective way of maintaining a calm lifestyle and strengthening the immune system so it can better fight off cancer cells. I garden frequently – it’s an enjoyable, serene way to diffuse stress. Plus, regular exercise outdoors can also do wonders for reducing one’s cancer risk and improving overall well-being. Not to mention all those cancer-fighting antioxidants found in fresh fruit and vegetables!” —Dr Amy Lee

“Sunscreen is a great first defence but it’s not the only way to protect yourself from harmful UV rays. I always wear a broad-rim hat and sunglasses with UV protection when I’m outdoors. In addition, I schedule my favourite sport, golf, to avoid playing during the sun’s peak hours.” —Dr Hubert Greenway, skin cancer specialist

“People who are physically active live longer and have lower risks for heart disease, stroke, type 2 diabetes, depression and some cancers. Obesity and a sedentary lifestyle have been implicated in cancer-causing deaths,” including common cancers like breast and colon cancer. —Dr Delphine J. Lee, PhD, dermatologist and cancer research laboratory director

“Tobacco products are very strongly linked to the development of a number of cancers, including those of the lung, head and neck, oesophagus, pancreas, kidney, bladder, colon and rectum, among others. In fact, tobacco products account for at least 30% of all deaths from cancer and lung cancer is the number one cause of cancer deaths in both men and women. So, the practice of avoiding or quitting tobacco can dramatically reduce one’s risk of developing a cancer in their lifetime.” —Dr Jeffrey Vainshtein, radiation oncologist 

“As a neuro-oncologist, I’m well aware of how important it is to keep our brains active and alert at all ages. I do this with simple changes in day-to-day activities. Brushing my teeth with my non-dominant hand, for example, is an easy way to change my routine. Even a small change like this causes an increase in the level of connectivity between the neurons in the brain. Teaching yourself new things and challenging yourself on a daily basis will keep your brain healthy and resilient.” —Dr David Poulad, neurosurgeon specialising in neuro-oncology 

“I make sure to eat a wide variety of produce. According to the CDC, diets rich in fruit and vegetables may reduce the risk of some types of cancer and other chronic diseases.” —Dr Delphine Lee
