A Cell in Psychosis
Late drive. Empty road. One thought landed and would not leave.
Cancer is a cell in psychosis.
Not clinically. Metaphorically. Structurally. The same failure at two different scales.
A healthy cell stays in touch with the tissue around it. It reads signals from its neighbours — where to grow, when to stop, when to die, what to be. Its identity is not just in its DNA. It is in that constant negotiation with the collective. Its self is defined by embedding.
A cancer cell loses that. Contact inhibition fails — it stops knowing where it ends. Apoptosis signals arrive and get ignored — it stops recognising when it should stop. Differentiation slips — it stops being what it was. Internal signalling drowns out the external correction loop. It becomes pathologically autonomous. It acts on its own logic, and its own logic has drifted from anything the body around it recognises.
Now describe psychosis with the same words.
A person in psychosis loses contact with shared reality. Stops knowing where self ends and world begins. Consensus feedback arrives and gets ignored. The internal narrative drowns out external correction. Identity fragments. The system becomes pathologically autonomous. Acts on its own logic. That logic has drifted from anything the people around them recognise.
Both are a unit losing its embedding in the larger regulatory context that gave it meaning. Both are the collapse of the feedback loop that used to tell it what it was for. Both are, in that specific sense, the same shape of illness.
The immune system's job is partly to recognise self-vs-non-self and eliminate misfiring self. That is roughly what a healthy social fabric does for a person breaking down. Sometimes it works. Sometimes it doesn't.
The metaphor strains where the substrates strain. Cancer replicates the pattern outward through tissue in a way psychosis does not through neurons. But the shape holds. And the shape is the interesting bit.
Anyway. That was the drive.
Not a diagnosis. Just a thought that would not sit down.
