I am not too clear about the connection between cancer cells and immune system response. It is clear the primary correlation between stress and immune deficiency is improper regulation of neurotransmitter GABA. Since that connection is firmly known it could be that improper immune system regulation either spreads the conditions that allow cancer formation or reduces the immune response to fighting cancer.
The primary cause of anxiety is chronic stress. Chronic stress most typically occurs when a fear or aggression memory is stamped in the amygdala in the brain. The left and right amygdalas are asymmetrical and process different tasks in humans, by the way. In a healthy person a fear memory is generated in the amygdala which loops through other areas of the limbic system before coming back to the amygdala with additional emotional processing, but before looping more the fear process is halted by flooding the amygdala with a suppressor, GABA. In unhealthy people GABA is not released into the process at appropriate moments resulting in a run away loop of building negative emotions. GABA is also produced, as a regulator, by the immune system.
As an aside the immune system also produces another neurotransmitter responsible for both immune system excitement that plays an unrelated role of emotional motivation in the brain. That is why antihistamines medications make people drowsy, because suppressing that neurotransmitter via medication occurs in utero.

You mean histamine? I think antihistamines make people drowsy, because histamine signaling at the H1-Receptor is involved with regulation of the circadian rhythm [1][2]. As far as I know, histamine is released, as part of the immune system, by mast cells, which have to be triggered by IgE (parasite / "macro stuff" / "allergy") antibodies.
Neither the "H1 receptor", "H1 antagonist", "Histamine", "Tuberomammillary nucleus" nor "Mast cell" Wikipedia article match "GABA".
