Te rongoa rama whero (RLT) has become a popular tool for reducing inflammation, supporting healing, me te whakapai ake i te hauora kiri. But for those who are currently dealing with breast cancer — or have a history of it — the question arises: Is it safe?
He aha te Maama Whero?
Red light therapy uses specific wavelengths of red (te tikanga 630–660nm) me te rama tata-infrared (800–850nm) ki te whakaongaonga hanga pūngao pūtau (ATP), whakaiti ahotea hāora, a te whakatairanga i te whakatikatika kiko. It’s widely used in skincare, whakahaere mamae, and post-surgery recovery.
Concerns with Cancer and Light Stimulation
The core concern is that red light therapy stimulates cellular activity — and in the context of cancer, especially hormone-sensitive types like some forms of breast cancer, this raises caution. While RLT doesn’t use harmful UV rays and is non-ionizing, its ability to boost cell function makes many oncologists recommend avoiding direct application over known or suspected tumors.
He aha ta te rangahau?
- There is no strong evidence that red light therapy causes cancer.
- Ko etahi animal and lab studies show red light may support immune function or reduce treatment side effects.
- Heoi ano, human clinical research on RLT in active cancer patients is limited.
Mo breast cancer survivors, red light therapy may help with:
- Scar healing after surgery
- Lymphedema management (swelling due to lymph node removal)
- Fatigue and muscle pain caused by chemotherapy or radiation
But always under medical supervision.
Safety Guidelines
- Do not apply red light directly over a tumor or affected breast without doctor approval
- Avoid RLT if you are undergoing active cancer treatment, unless supervised
- Breast cancer survivors can consider RLT for non-cancerous areas (e.g., kanohi, hononga, nga whiu), but still should consult their oncologist
Nga Whakaaro Whakamutunga
Red light therapy is generally safe for healthy individuals, but for those with current or past breast cancer, caution is essential. Always consult your oncologist or medical team before using red light therapy — especially over the chest area.
