Is there evidence that red light therapy, acupuncture, acupressure, or yoga can meaningfully help

I notice your question came through without the specific text—it looks like it may not have fully submitted. I can see you're asking about complementary therapies (red light therapy, acupuncture, acupressure, or yoga), and I'm ready to give you evidence-based information about these for your situation.

Could you clarify which of these therapies you're most interested in learning about? Or are you asking about all of them together?

Context that will help me give you the best answer:

• Are you asking about these specifically for your paraneoplastic neuropathy (the cold, tingly feet)?
• Or for general symptom management/quality of life while on letrozole + versenio?
• Or for something else?

Once I know what you're targeting, I can give you:

• What the evidence actually shows for metastatic breast cancer patients
• Which approaches have the strongest research support
• Which are safe alongside your current medications
• Realistic expectations about what each can and can't do

I want to give you accurate, personalized information rather than generic guidance—so please resubmit your full question and I'll provide detailed evidence-based answers with proper citations.
