I apologize. When I posted the link to PUBMED, it cleared my search results on the site so it didn't show anything that I found in my search.
Using "Photo Therapy", I found the following study near the top of the list. I discounted laser surgeries.

Photodynamic therapy is a new modality of therapy being used for the diagnosis and treatment of many tumors. It is now being increasingly used for
skin tumors and other dermatological disorders. With its range of application it is certainly the therapy of the future. Its mechanism of action is by
the Type II photo-oxidative reaction. The variables are the photosensitizer, the tissue oxygenation and the light source. It has been used to treat
various disorders including Bowen's disease, actinic keratoses, squamous cell carcinomas, basal cell carcinomas, and mycosis fungoides. The
side-effects are fortunately mild and transient. Newer photosensitizers like methyl aminolevulinate hold a lot of promise for better therapy.

As I said in my above post, it is not a cure-all, but they are finding more uses for light therapy. I found a bunch of abstracts for light killing
bacteria in the lab, but it wasn't what I was really looking for.
I also did not link to "sound therapy" that listed using sound waves to destroy kidney stones and such.
I found some other studies about "sound therapy" on there, but I'm too tired to bring up all the abstracts and read them to see if they showed
positive or negative results.
Best,
