I remember watching this movie on TV when I was a kid. It must be around 1997-98, but I'm not sure. Of course, the movie itself must be older.
It was about a strange, otherworldly tower-like structure suddenly appearing on a desert-like place (probably somewhere around Middle-East, again not sure). It had healing powers around its surrounding area. One of the main characters had a cancer (lung cancer maybe) and when he came around this structure he was gradually healed.
I remember a specific line in the movie that goes: (Wording might not be the same.) "This thing might be what we call The God for thousands of years."
Once it was discovered, there was a military occupation around and they were arguing about whether or not to destroy while main characters were trying to save it. At some point, they were going inside the structure.
I could not find the movie. Maybe I misremember some things. Anyone have an idea?
