Supporting Your Mind and Body

Physical Activity and Exercise

Moving Throughout Breast Cancer

When you receive a breast cancer diagnosis, it’s common to feel a loss of control over your body. Treatments like surgery, chemotherapy, radiation, and hormone therapy can bring major changes. Many young adults—both in and beyond treatment—find that adding movement to their routine helps restore a sense of self.

Exercise offers meaningful benefits and can help reduce some of the most common side effects from treatment.  It can support heart and bone strength, reduce stress, improve sleep, and increase energy for daily life, from meeting work demands to caring for children. Some research also suggests regular physical activity may reduce the risk of recurrence.

Shift Your Mindset for Success

Whether you’re in treatment or beyond it, getting started with exercise can be a challenge. These step-by-step approaches from Exercise Physiologist Nancy Campbell, MS, of Dana-Farber’s Zakim Center for Integrative Therapies and Healthy Living can make it easier.

What the Research Shows

Young adults with breast cancer are more likely than older adults to gain weight during treatment. That may be due to fatigue, early menopause, emotional challenges, or the side effects of chemotherapy. Still, studies show that staying active—even a little—can make a real difference.

Recommendations from Cancer Experts

To get the most benefit from physical activity:

After Surgery

Return to your normal activities as soon as your care team says it’s safe.

During and After Other Treatments

Stay active however you can—small amounts still count.

If You’re Just Getting Started

Talk to your doctor or care team about safe ways to begin. Working with a physical therapist or certified cancer exercise specialist may be effective in helping you develop an individualized plan.

How Much Exercise Should I Get?

Your ideal exercise plan depends on your age, activity level before treatment, current energy levels, and any side effects or other medical concerns. Some people may need a personalized approach, especially if experiencing:

  • Extreme fatigue
  • Osteoporosis
  • Peripheral neuropathy
  • Other potentially limiting health conditions (ie: arthritis, cardiovascular disease)

Before starting any new activity, talk with your doctor or care team. They can help you choose safe options based on your unique needs and health status.

Getting Started

Suggestions:

  • Begin slowly and increase your activity level gradually, ideally never more than 10% from week to week, to reduce the risk of over-use injuries
  • Break up exercise into shorter sessions—like 10-minute increments throughout the day
  • Build toward 30 minutes of movement daily
