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.
For most people, a cancer diagnosis brings the daily routine of life to a grinding halt, at least temporarily. But after the initial shock wears off, many patients strive to resume their everyday activities, including vacation or travel plans. Being treated for cancer doesn’t necessarily mean cancelling your summer vacation. Many people travel during and after cancer treatment. But it can require a little planning.
Watch and wait. That’s often one of the new terms added to your vocabulary when you’re diagnosed with cancer. Or maybe it’s wait and watch. Or active monitoring. Whatever it’s called, sometimes it’s the term used when there’s nothing to do to treat your particular cancer but wait. That’s a hard thing to do, most doctors will tell you. The natural reaction to a cancer diagnosis is a desire to do something, anything. Melt it. Burn it. Radiate it. Drug it. Remove it. Attack it. Just get the cancer out of you.
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.
May is Melanoma Awareness Month. Often caused by excessive exposure to ultraviolet (UV) rays in sunlight, melanoma accounts for only 4 to 5 percent of skin cancer cases, but is responsible for most skin cancer-related deaths. When detected and treated in its earliest stages, however, melanoma is often curable. The key is to avoid overexposure to UV rays – by limiting time outdoors during the peak hours of sunlight and wearing sun-protective clothing and sunscreen – and to be on the lookout for changes in moles and other blemishes that can be an early sign of the disease. As with …
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.
For many women who enjoy a glass of wine, research showing that relatively small amounts of alcohol can raise their risk of breast cancer are disconcerting, to say the least. And confusing, too. How much drinking is OK? Isn’t a glass of red wine a day good for your heart — and couldn’t that be more important? In the past five or 10 years, knowledge about alcohol and breast cancer has been changing as studies produce new results and are publicized, sometimes over-dramatically, in the media. At the same time, there’s growing evidence that moderate drinking can be healthy for …
If you’re over 50, have you been screened for colorectal cancer? If not, the month of March would be a great time to talk about screening with your doctor. Colorectal cancer is the third leading cause of cancer in men and women in theUnited States. In 2012, an estimated 141,210 people will be diagnosed with colorectal cancer and 49,380 will die of the disease. But it’s also a very curable cancer when it’s caught early. A new study published in the New England Journal of Medicine in February that tracked patients as long as 20 years shows that colonoscopy screening …
