Can I exercise during Colorectal Cancer treatment

Exercise During Colorectal Cancer Treatment

Yes, you can and should exercise during colorectal cancer treatment—but the approach needs to be tailored to your specific situation and what you're currently undergoing.

What the Evidence Shows

According to NCCN Guidelines for Colorectal Cancer, physical activity is strongly supported during and after treatment. Research has consistently shown that exercise improves outcomes:

• In studies of patients with stage III colon cancer undergoing chemotherapy, those who engaged in regular physical activity had better disease-free survival (DFS) compared to those who were sedentary
• Physical activity has been shown to improve quality of life and reduce depression in colorectal cancer survivors
• Both pre- and post-diagnosis exercise decreases colorectal cancer-specific mortality

General Recommendations During Treatment

The NCCN Guidelines recommend:

At least 30 minutes of moderate-intensity activity on most days of the week (when tolerable during treatment)

This might include:

• Walking
• Swimming
• Cycling
• Light strength training
• Gentle yoga

Important Modifications Based on Your Treatment

Your exercise plan may need adjustment depending on what you're experiencing:

If you have an ostomy (surgical opening for bowel function):

• Activity recommendations may require modification
• Consider participation in an ostomy support group for practical guidance
• A healthcare provider specializing in ostomy care can help you exercise safely

If you're experiencing chemotherapy side effects like neuropathy (nerve damage/numbness):

• Modify activities based on your symptoms
• Avoid high-impact exercises if balance is affected
• Work with your care team on safe alternatives

If you have chronic diarrhea or bowel changes:

• Diet recommendations may be modified based on bowel dysfunction severity
• Time exercise around bathroom needs
• Stay well-hydrated

How to Approach This Safely

STEP 1 - Talk to Your Oncology Team First: Before starting or continuing any exercise program, discuss with your cancer care team:

• What type of treatment you're currently receiving
• Any side effects you're experiencing
• Physical limitations from surgery or other treatments
• Whether you have any restrictions

STEP 2 - Start Gradually:

• If you weren't active before treatment, start with gentle walking
• Gradually increase duration and intensity as tolerated
• Listen to your body—some days you'll have more energy than others

STEP 3 - Consider Professional Guidance:

• Ask your oncology team for a referral to an exercise physiologist or physical therapist
• They can design a program specific to your treatment phase and side effects

Specific Questions to Ask Your Care Team

1. "Given my current treatment plan, what type and amount of exercise is safe for me?"
2. "Are there any activities I should avoid right now?"
3. "What side effects should make me stop exercising and contact you?"
4. "Would a referral to an exercise specialist or physical therapist be helpful?"
5. "How might my exercise plan need to change as my treatment progresses?"

Why This Matters

Exercise during treatment isn't just about fitness—it helps with:

• Managing fatigue (a common side effect)
• Maintaining muscle strength
• Improving mood and mental health
• Supporting better treatment tolerance
• Reducing risk of recurrence long-term

According to NCCN Guidelines, the evidence is strong enough that survivors of colorectal cancer should be encouraged to maintain a physically active lifestyle throughout their lives, with modifications based on treatment side effects.
