Bromide Drag or X-ray damage?

Here is a copy of the negative digitized using a DSLR. Poor quality but all I can grock right now.

Sometimes I think I can see it, sometimes not.

I did have light leaks from the back but very seldomly and they always looked like a small jet of light starting from a corner and going up to the center. Never seen this pattern before.

I was suggesting a light leak (likely very low level) after the film is in the developing tank, not one in camera. However, I see only the faintest hint of the bands in this version, and I can't be sure it wasn't in the scene (it doesn't run through the sky at the top). On that basis, I'm going to drop my suggestion of a developing tank leak, and gang up with the others to suggest it may be unevenness in you scanner's light source. Can you make an optical print of the negative? That'll tell you everything.

I think someone might have mentioned in camera.

I'll make an optical print soon and update with the situation.

The vertical bands - they look like waves - are so subtle, regularly spaced and long...this looks machine made....which does not rule out the negative scanner (the Epson V800 mentioned by the OP).

The DSLR copy of the negative doesn't show any vertical banding (it shows other artefacts, but those probably related to the copy process). While it's not an ultimate proof that there isn't something in the negative itself, I would still see this as a strong indication that the banding problem was introduced through the scanning process.

I don't; I ran the image through GIMP really quickly and boosted the contrast so that any banding would become painfully visible, but there really is none that resembles the banding issue in the first post. So probably it was just a scanning artefact.

What I saw in the DSLR "scan" was a single vertical that might well have been just a coincidence of exposure in the original scene.

FWIW the roll in question was shot with a hasselblad so the lines run parallel to the length of the film.

With that in mind I'd assume I would see the lines clearest of all in between frames but can't see anything of the sort.

If the OP's film was 120, what I'm about to say isn't related, but it might be interesting. The marks he showed reminded me of when I first tried out Mr Qualls' excellent monobath - just dropping the film into the tank resulted in rather dramatic surge marks from each sprocket hole on the side of the film lowered in first, that I had to swap to using the monobath in a Rondinax. That didn't get rid of the surge marks, but it did at least make them align along the length of the film and confine them to the border. I took a photo of two films hanging up to dry, one from the Rondinax and one from a Paterson tank. It's digital, so I won't embed it here. It's on Flickr here.
