I've received an interesting question from a patient about the potential negative effects of flying ✈️ for women with Breast cancer.
👍 The short answer:
Flying itself does not cause Breast cancer and does not worsen the condition.
However, there are some important nuances to keep in mind.
❓Can flying trigger the development of Breast cancer?
No. Currently, there is no evidence that air travel increases the risk of developing Breast cancer.
While the effects of cosmic radiation✨ at high altitudes are sometimes discussed, radiation levels during normal commercial flights are too low to have a significant impact.
This is more of a concern for professional pilots 🧑🏻✈️ and flight attendants with many years of experience than for occasional passengers.
❓What about flying for women already diagnosed with Breast cancer?
👍 In most cases, it is perfectly safe.
However, the decision depends on the stage of treatment and your overall health.
ℹ️ Key points to consider:
✔️ After surgery:
Flying is possible once your general condition has stabilized, but always check with your surgeon regarding the specific timing.
✔️ During chemotherapy ☣️:
It is crucial to monitor your immune system. During periods when white blood cell counts are significantly low, flying and visiting crowded places is not recommended.
✔️Risk of thrombosis:
Long flights can increase the risk of blood clots, especially during treatment.
I recommend moving around the cabin, staying hydrated, and potentially wearing compression stockings (if approved by your doctor).
✔️ Lymphedema (Lymphostasis):
After axillary (armpit) lymph node removal, there is a risk of arm swelling due to pressure changes.
A compression sleeve is often recommended during the flight.
✔️General well-being:
Fatigue and nausea are common side effects of treatment.
Plan your travel to allow for extra rest.
🚫When to postpone a flight:
- Early postoperative period.
- Severe side effects from treatment.
- Unstable general condition.
ℹ️ Conclusion:
Flying is not dangerous in terms of cancer progression.
However, if you are currently undergoing treatment, please discuss your travel plans with your Medical oncologist 👩🏻⚕️ to ensure your trip is as safe and comfortable as possible.
