Obesity and cancer: What’s the link?

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.

Adult stem cells may hold key to better health

Sarah Knauss, famous for being among the oldest people in the world until her death at the age of 119, might have had more than just “good genes.” Dana-Farber’s Wayne Marasco, MD, PhD, says that adult stem cells – known for their healing and regenerative properties – might hold the key to a long and healthy life. Marasco shared his expertise on the subject at the recent International Vatican Conference on Adult Stem Cells in Vatican City, Italy, an event attended by a select group of cardinals, clergy, and leading researchers and physicians from around the world. “We have learned …

HPV linked to head and neck cancer

Traditionally, patients with oral cancers tended to be older individuals with a long history of smoking and heavy alcohol use. In the past decade, however, that picture has changed dramatically. Today, infection with the human papillomavirus (HPV) is the leading cause of oropharyngeal cancer in the U.S. and Western Europe. Oropharyngeal cancers affect the back of the throat (i.e. the tonsils and base of the tongue). HPV is the same virus that causes most cases of cervical cancer in women. Patients with HPV-related head and neck cancers are often relatively young, not heavy drinkers or smokers, and come from all …

The benefits of vitamin D

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.

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 …

Coping with the holidays when you have cancer

The holidays can be a festive time, but for people dealing with cancer, they can also be stressful and full of anxiety. For many patients and their families, the thought of preparing for the season may be met with mixed emotions. And while parties and gift-giving often go hand-in-hand with the holiday season, you might not have energy for either if you’re going through cancer treatment. Nausea might make the thought of cookies and chocolate cream pie much less appealing, and just running a quick errand can leave you exhausted, never mind a marathon shopping trip. To help you prepare, …
