thread_title:  A rewrite 

message: "When the photosensitizer and an oxygen molecule are in proximity, an energy transfer can take place that allows the photosensitizer to relax to its ground singlet state, and create an excited singlet state oxygen molecule"
This is only true with some PDT drugs.  Newer drugs are composed of dinuclear or trinuclear complexes containing a light absorbing unit, a bridging ligand, and a biologically active site that undergoes metal to metal charge transfer.  So when targeted with photons of a certain wavelength the light absorbing unit loses an electron (photoelectric effect?) which travels across the ligand and reduces the metal at the biologically active site and causes the cleavage of DNA.  This method of action is completely independant of molecular oxygen and does not produce singlet oxygen in the body.
"...involving three key components: a photosensitizer, light, and tissue oxygen"
"and tissue oxygen" should be removed.
: Can anyone provide sources for that please ? Rod57 (talk) 15:29, 2 March 2011 (UTC)

message: Inventor Terry Wright is currently working on new light arrays for use in PDT.  Please see his website at Cytoluminator.com.

TERRY WRIGHT has now been proven to be a fraud, and charges 45k.  Convinces people through his "tough demeanor and talk over Skype acting like a smart scientist."  When in fact he is the most evil man in the alternative field.  Many patients of his have died(all of them), he is a master manipulator.

In EPP the last step of heme biosynthesis is affected (fixing of iron inside the protoporphyrin IX- ring) which causes PPIX accumulation and reactions to visible light similar seen in PDT. In PCT other heme precursers accumalate (Uroporphyrins, Heptacarboxylporphyrin and Isocoporphyrin), but not PPIX.  —Preceding unsigned comment added by 195.176.146.92 (talk) 14:30, 31 March 2008 (UTC)
thread_title:  PTD with PPIX mimics Erythropoietic Protoporphyria, not Porphyria cutanea tarda! 

message: Perhaps some sections could be added describing the current range of photosensitizers and specific conditions for which PDT has been approved.  I'll try to incorporate this and other general info the next chance I get. Afireinside13t (talk) 03:22, 30 June 2008 (UTC)

thread_title:  Hollow needles for deeper cancers 

message: The huge photo and overall feel of the document give the general feeling that this technique is useful as a surgical one, "during surgery", but the little section on light needles strongly implies that actual surgery might be very nearly completely unnecessary, especially if used in conjunction with ultrasound imaging to visualize the areas inside and around the tumor.
Can the technique also be used with endoscopy instruments carrying an additional fiber optic cable for the purpose of adding the sensitizing wavelength? Seems an obvious enough application that it must have been tried by now, is it ineffective or does the article just lack text about such possibilities?Zaphraud (talk) 18:46, 8 January 2009 (UTC)

message: New agents are being sought that do not depend on oxygen (since tumours can be low in oxygen) Activated Molecules Kill Tumor Cells Only Where Light Shines - probably need to mention here somehow. - Rod57 (talk) 13:41, 27 April 2016 (UTC)

message: A recently published review (https://www.mdpi.com/1420-3049/27/20/6967) describes the metal coordination effect on the photophysics of dipyrrinato complexes for photodynamic therapy.
