Cancer metaphor

No but I saw ur mom dressed up as a fly.

Not really. I felt the movie was more of a cautionary tale regarding hubris. Like a twisted version of Icarus. Though your idea is interesting, because people can give themselves cancer through their actions/lifestyle choices, just as he contaminated his body with his experiment. But cancer is also caused through inadvertent actions, and Goldblum was anything but inadvertent in his actions so I don’t think this movie’s narrative can truly fall into the ‘Cancer Metaphor’ category. But the physiology of cancer might have had an influence in production design.
Maybe it’s more of a ‘terminal disease’ metaphor, but not cancer-specific.

Neurofibromatosis to be exact.

Not at all. Flies and other insects don't get cancer

wow, there sure are a lot of dumbfucks in this thread.

the film is certainly metaphorical for cancer, or at least a general disease. Cronenberg admitted this himself, saying he wanted the film to represent a character who finally finds success receiving a terminal illness.
