In a recent discussion, a cancer expert highlighted the importance of exercise for breast cancer survivors, particularly in managing bone health and reducing the risk of recurrence. Here’s an in-depth look at their advice on physical activity, osteoporosis prevention, and weight-bearing exercises.

How Exercise Reduces Breast Cancer Recurrence

Exercise is one of the most effective ways to reduce cancer recurrence risk. Regular physical activity has been shown to positively impact both general well-being and specific cancer-related outcomes, including reducing the likelihood of disease progression. Exercise also helps alleviate common treatment side effects like fatigue, neuropathy, and joint pain, improving the overall quality of life.

Starting Small with Physical Activity

For those who may be dealing with side effects from cancer treatment, starting small with physical activity is key. Rather than aiming immediately for 150 minutes of exercise per week, which is the recommended guideline, survivors are encouraged to build up gradually. Simple movements, such as walking for five minutes or trying chair yoga, can be excellent starting points. Gentle activities like stretching, light weight-lifting with one-pound weights, or water exercises are also recommended, particularly for those with limited mobility due to treatment side effects.

Weight-Bearing Exercises for Bone Health

For breast cancer survivors, maintaining bone density is crucial, especially for those on endocrine therapies that can affect bone health. Weight-bearing activities, such as walking, squats, and lunges, are essential for maintaining or even improving bone density. Simple modifications, like walking with ankle weights or wearing a weighted vest, can make these activities more effective without requiring intensive gym workouts.

The expert emphasized that survivors can maintain and even improve their bone health without heavy weightlifting or extensive gym sessions. Walking with added resistance, body-weight exercises, and light resistance training can all make a significant difference.

Debunking Myths About Osteoporosis and Endocrine Therapy

Endocrine therapy, often prescribed for breast cancer survivors, has been linked to an increased risk of osteoporosis. However, this does not mean that osteoporosis is inevitable for all individuals on such treatments. Many survivors manage to stabilize or even improve their bone density through regular weight-bearing exercise. Additionally, calcium and vitamin D intake are crucial for supporting bone health.

For those who need additional support, bone-modifying medications like Prolia or Zometa may be considered, especially for those at higher risk.

Key Takeaway

Exercise is a powerful tool for breast cancer survivors to reduce recurrence risk and protect their bone health. By starting with small, manageable activities and incorporating weight-bearing exercises, survivors can experience physical and mental benefits that improve quality of life.
