Study: Obesity Increases Breast Cancer Risk, Preventing Weight Gain Key

Postmenopausal women who are overweight — and especially obese — have a greater risk of developing breast cancers, finds a new study that highlights the importance of preventing weight gain, as it also raises questions about whether losing weight necessarily reduces that risk.

The study adds to a consistent body of research showing that overweight and obesity increases women’s risk of postmenopausal breast cancers. It was published yesterday in JAMA Oncology.

AICR estimates that a third of US breast cancers could be prevented if women were at a healthy weight throughout life, were active and did not drink alcohol.

In this study, as other research has seen, the heavier the women, the greater the risk. Women categorized as the most obese were at almost double the risk of the most common type of breast cancer, ER-positive, along with PR-positive tumors. These cancers are fueled by the hormones estrogen and progesterone, respectively.

The study used data from approximately 67,000 women who were all part of the Women’s Health Initiative trials. That study focused on preventing certain cancers, heart disease and osteoporosis. When the women entered the study in the mid 1990s they were 50 to 79 years old, and they were weighed. They also answered questions about their lifestyle habits, medical history and other health risk factors. After that, they were weighed annually and had regular mammograms. Continue reading


Cancer Prevention Begins at Your Kitchen Table: Transforming the Cancer Agenda

Half of cancers – one of every two cases – can be prevented and so often it’s about applying what we already know. That was the simple but powerful message at the first Cancer Prevention Summit held by the New York State Department I attended last week. The overarching message of the Summit was simple: 50% of cancers can be prevented and in New York State, where approximately 35,000 people die from cancer each year, primary cancer prevention is an urgent public health priority.

50-infographic-bigExperts spoke about vaccinating against HPV and preventing tobacco use, two major causes of cancers. What fewer people may know is there are concrete things that we can do to reduce our risk. Maintaining a healthy weight, engaging in regular physical activity, and eating well can prevent approximately one of three of the most common cancers.

Summit highlights included:

Shift the discussion to the notion that “cancer is preventable.” Begin to focus effort and awareness on risk reduction through modifiable lifestyle habits. This includes eating a predominantly plant-based diet, achieving and maintaining a healthy weight, exercising regularly, using sunscreen, participating in cancer screening, and avoiding tobacco use and heavy alcohol.

Want to Sip on Something Sweet -and Healthy? Try this.

Although most people recognize that soda may pose health risks, many are unaware of the damaging effects of other ‘sugary’ beverages, such as fruit and sports drinks. (It was the topic of a Cancer Research Update last month.)canstockphoto14236519

It’s easy to gain weight from drinking sweetened beverages, and since obesity is linked to increased cancer risk, decreasing consumption of these drinks can help you both lose weight and decrease your cancer risk.

However, if you’re like me, you might not enjoy drinking plain water. This can make it challenging to cut back on sweetened beverages.

If you regularly drink juice, soda or sports drinks, start by using smaller sized cups and set goals to wean yourself off rather than going cold-turkey. For example, instead of 3 cups per day, reduce the amount to 1 cup per day, then after a week or two, reduce the amount further to 1 cup every other day. Write out a plan that will allow you to wean off of the beverage completely (or to only 1 time per week) over the next few months. I have seen this strategy work very well for patients of mine – it’s easier to adapt if you change your behaviors slowly.

In addition to cutting back, find low-sugar beverage alternatives you enjoy to have instead. Here are some of my favorite alternatives to sugary drinks that are still full of flavor, and just a tad sweet:

Iced teas – Try out different types of tea until you find one you like (or continually change it up so you don’t get bored). Some great options are mint, passion tea, hibiscus, chai or black raspberry. Make a big batch on the weekend and keep it in a large pitcher in your fridge. If you still need a little sweetness, add just a teaspoon of honey or agave to your tea (or one tablespoon for the pitcher). Some of these teas, like chai, taste great with a little skim or almond milk.

Flavor your water with fruit – You can simply add fresh lemon or lime, but if you’re looking for sweeter flavors, try combinations like fresh pineapple and mint, pear with fresh ginger and a cinnamon stick, or a handful or any frozen berries (which helps cut the cost of using lots of fresh fruit). Most fruit will stay fine for a week when kept in the fridge, so you can keep adding water to the pitcher as it empties (and change out for new fruit once a week). For more ideas, read this  blog I wrote on flavoring your own water.

Sparkling water and juice – Instead of a full glass of fruit juice, fill your cup with sparkling water and add just a splash of your favorite juice (orange, grapefruit, pineapple or cranberry are all good options).
