Regor and others,
A couple of experiences about cancer detection.
Blue-light is not a magic diagnostic tool. Neither is a CT Scan.
If you are a veteran, you may be able to have blue-light done at a VA facility. If you are treating outside the VA, you may have a bunch of hoops to jump through to get just blue-light, and you may need to travel to a VA facility that has it.
Blue light has failed, so far, to identify my CIS that is not seen under white light. It has also failed, along with white light, to show cis even when CIS has been found by random biopsies. The standard of care, as has been explained to me repeatedly, is the random biopsy. I'm not happy about that either. Fact is, CIS can be hard to identify, particularly of is starts to burrow in or for nests. Various institutions are currently conducting Blue light studies - I have been in a study for over a year - the goal is to determinw WHEN blue light will be effective.
Life would be sweet if the popular press' articles on 'cancer advances' stuck to the facts instead of touting the advance as the next sliced bread.
CT rarely shows CIS except sometimes as a 'wall thickening', which is not diagnostic by itself. CT is rather insensitive to small growths in the bladder, and many but not all are missed. The best CTs I have had are with up-to-date software, a 3 Tesla magnet, and very small "slice" distance.
There is a reason for all the tests - CT shows more than the bladder - cytology, is a screening test that is best at suggesting high grade, but with false positives and negatives.
The "Gold Standard" and I hate that term, remains the cystoscopy and TURBT. At least for me.
I understand the desire for blue magic, I had to battle for it, but I gained nothing, sadly. Hopefully others can offer positive results from Bluelight.
Best
Jack
