Exercising After Breast Cancer: Myths vs. Facts

The benefits of physical activity for people who have undergone treatment for breast cancer are numerous, from reducing fatigue to helping regain a sense of well-being. However, as with diet recommendations, it can be confusing when it comes to how much exercise to take and the type of exercise that is safe during and after treatment.

Recently, I spoke with Cathy Leman, a registered dietitian, nutrition therapist, personal trainer, and survivor of hormone-positive breast cancer. Cathy shared many helpful tips and strategies for those who may be unsure where to start with an exercise routine after a diagnosis of breast cancer.


What are some of the myths associated with exercise and breast cancer? When I had my surgery, I thought I shouldn’t lift anything heavy, such as weights.  And that rest is the best way to heal. Are these beliefs true?


The two thoughts you had are very common! Immediately post-surgery, there definitely are weight limitations in place, yet once your doctor removes exercise restrictions, and gives clearance, there are no limits (other than an individual’s physical ability) on how heavy one can lift. Exercise also helps restore mobility and range of motion after surgery, and there is research identifying exercise as a way to support healing. By the way, it’s important to ALWAYS get your doctor’s approval to add or increase exercise post-surgery.


That’s wonderful to hear, Cathy.  Let’s talk about the benefits of exercising now that we have been cleared to start.


There are so many! Increased range of motion and improved mobility, reduction in fatigue, improvement in strength and stamina, and stress and anxiety management.


What would you suggest to someone who feels intimidated by the current exercise guidelines, which recommend 150 minutes of exercise per week? You may feel exhausted from cancer treatment and this can seem like an overwhelming task.


150 minutes per week translates to ~ 21 minutes per day. I recommend breaking that down even further, for example, 10 minutes of activity in the a.m. and 10 minutes of activity in the evening. Start small, with easy stretches and a walk around the block.


I really like the idea of breaking exercise down into manageable chunks this way.  Okay, let’s move on to where and how to exercise. Gym visits may not be an option for everyone, especially because many of us are still cautious about being in public spaces due to Covid. How can we replicate some of the traditional gym exercises at home?


Body weight exercises like squats, lunges, modified push-ups and planks are great for building overall body strength. Walking or running outdoors offers great cardiovascular benefits. During inclement weather, dancing, walking up and down stairs, and using online in-home workouts are ways to keep moving, even without visiting the gym.


Thanks Cathy for taking the time to talk to us about exercising in ways that are achievable and beneficial, and dispelling some of the common myths around exercise and breast cancer.

A Word From the Registered Dietician & Nutritionist

How Much Protein Do I Need?

Each person’s nutrient needs are a little different, and you actually have some leeway with how much of each to have. However, when it comes to macronutrients (protein, carbs and fat), it’s not the same rule. We want to get enough, without too much. There are varying suggestions on what the correct ratio is for macronutrient intake, but they typically fall within the following range:

  • 45-65% of calories from carbs
  • 20-35% of calories from fat (I’ve seen some studies show Mediterranean diets that have up to 40%)
  • 10-35% of calories from protein

NOTE that these are not percentages of food on the plate, they are percentages of CALORIES from each food group. What makes this extra confusing is that carbs and protein are 4 calories per gram where fat is 9 calories per gram. Fat is very calorie dense, which is why you aim to eat less of it by volume, than the other sources of calories. Less is more!

Also, FYI – alcohol is 7 calories per gram. That’s still more calories per gram than carbs and protein. It can add up fast, hence the ‘beer belly’ that some people can accumulate even when it seems that they don’t “eat” that much.

Given this information, what is the optimal amount of protein that you should aim for? Consuming more protein than your body needs is not helpful. The average American eats twice as much protein as they need (they fill 1/2 their plate with meat!)
