Pardon my ignorance, but how does lox relate to Pisces? I don't get the connection with cancer either, but the first thing that comes to mind on hearing Lox is liquid oxygen as it is used in rockets. So it's a connection between Rust language and astrodynamics. Is there something that makes Pisces more appropriate for this?
I assume they’re making a reference to Lox the food (brined Salmon), so a fish is appropriate.
Sibling comment mentioned the connection between lox and Pisces, but the connection to Cancer is that the mascot for Rust is a crab.
