There’s no better time to barbecue with family and friends than the summer, but grilling meat creates chemicals that may be linked to cancer. Research has shown that high-heat grilling can convert proteins in red meat, pork, poultry, and fish into heterocyclic amines (HCAs), chemicals that have been connected to a number of cancers. Another cancer-causing agent, called polycyclic aromatic hydrocarbons (PAHs), is found in the smoke. PAHs form when fat and juices from meat products drip on the heat source, causing smoke to form and stick to the surface of the meat as it rises.
Processed foods have become a staple in the U.S., making up as much as 90 percent of American diets. Pre-prepared meals are often less expensive, and save working, busy people time at the end of a long day. However, research from the Organic Trade Association shows that trends are beginning to change. Sales of organic products grew by about 5 percent in 2009, reaching a total of $26.6 billion. And fruits and vegetables, the most popular corner of the organic market, increased sales by 11 percent, or $9.5 billion.
Genes don’t cause cancer, but genetic mutations can. Our cells have about 22,000 genes, which consist of DNA packed into chromosomes inside the cell nucleus. These genes control a wide range of functions, including cell growth and division. When the genes misbehave or mutate, cancer can develop.
If you think a cancer diagnosis automatically means you’ll need to get plenty of bed rest and avoid activity, think again. A host of medical studies show that exercise can not only reduce the chances of developing cancer, it’s also safe during and after cancer treatment, helping improve quality of life, increase energy levels, and decrease the fatigue that many patients report. Here are some tips for starting your own fitness routine, even if you’re facing the challenge of cancer.
In celebration of Living Proof week, Insight honors cancer survivors with daily posts about survivorship. When I was discharged from the hospital in 1996 after undergoing a stem cell transplant to treat leukemia, I was terrified. Yes, I’d survived cancer treatment, but now I had to deal with something even scarier: the unknown. If you’ve recently ended active treatment and are entering the world of survivorship, here are some tips to keep in mind. It’s OK to feel isolated at first. The end of cancer treatment can bring negative emotions, particularly when those around you think you should be “getting back to normal.” Leaving the safety …
In low-income, minority communities, tight-knit social connections can lead people to eat right and be physically active — but they can also sometimes be an obstacle to a healthy lifestyle, according to new research by investigators at Dana-Farber and the Harvard School of Public Health. The findings present a mixed picture of the benefits and potential downsides of social ties as they relate to a healthy lifestyle.
Bryan Reilly has a full-time job and a passion for exercise. He skis, climbs mountains, works out regularly, and runs a mile in under 8 minutes. Any 56-year-old could be proud of being so fit. But for Reilly, it’s a special triumph: Less than two years ago he was diagnosed with an often-lethal and aggressive brain tumor.
Cancer cells have a voracious appetite for glucose, a form of sugar, and consume it in much greater amounts than normal cells do. The knowledge of cancer cells’ zest for sugar has led some people to wonder if eating less sugar would restrain tumors’ growth. While cancer cells do rely on a large intake of glucose to fuel their growth and proliferation, reducing sugar in your diet won’t curb tumors.
There are a lot of good reasons not to gain too much weight, but you might not be aware of this one: Growing evidence links obesity to a higher risk of developing cancer, and being overweight may worsen a cancer patient’s outlook. Although more and more studies are finding this connection, scientists haven’t uncovered the biological mechanisms by which excess pounds make normal cells more likely to turn cancerous. But they are pursuing a large number of leads, some of which may uncover new ways of fighting cancer – including losing weight.
Activated by sunlight and present in some foods and supplements, vitamin D has been associated with healthy bones and reducing the risk of diabetes and cancer. But a new study says that the recommended dose of vitamin D needed to reap these health benefits remains unclear. To help shed some light on the topic, we talked to Dana-Farber’s Kimmie Ng, MD, MPH, who has been studying the connection between cancer and vitamin D use, as well as other lifestyle factors. What is the connection between cancer and vitamin D? There is a large amount of scientific and observational data that …
