Question: Academic question.
I had flu-like symptoms, especially fever, cold limbs, spontaneous sweating, headache, sore throat, vomiting and nausea when I had oesophageal cancer (2004). I realize now that the conditions were consistent with an aggressive cancer. I was wondering how does the medical community explain the flu-like symptoms?

So what I understand from what you are saying is that the medical view is that the flu-like symptoms are considered to be the flu and attributed to a weak immune system. I have a different explanation. I'd like to know what you think.

Three emotional conditions can create flu-like symptoms.
The presence of fear and anger if present (used to make a person fight more aggressively and hence faster growing cancer) raise the metabolism. Worry, which is circular thinking lowers the metabolism.

Fear and anger give rise to high energy states hence fever.

The three together cause spontaneous sweating and cold limbs.
Spontaneous sweating because each time the metabolism goes cyclically from low to high repeatedly, so it triggers the sweating mechanism.

Fear and anger through SNS give signals to the heart to go fast and worry through actions of PNS give signals to go slow. The heart muscles become adversely affected and the heart becomes ineffective as a pump. So the blood circulation is not good enough to bring enough fuel materials to the extremities.

nausea because the stomach is conflicted. Fear deactivates digestion while PNS, which facilitates thinking and resting metabolism, activates digestion.

vomiting due to fear and deactivated digestion so if severe enough will expel the stomach contents.

headache because the person is involved in thinking excessively in a state of fear usually and it can be subconsciously expressed so high activity may affect brain supporting structures as they have pain receptors.

That leaves the sore throat, which is due to inflammation. This means that ideas/ beliefs relating to some problem in the throat, eg a person hassled in the office by toxic co-workers may be given the suggestion of "ramming it down my thoat". That idea can be conveyed with mental images of something being pushed into the person's throat. Hence an unnecessary immune response. Commonly seen in cancer.

None of these can be treated with antibiotics because none is due to any microorganism.

Also consider a tumor expresses receptors on the surface and the creation of a micro environment including deactivation of T cells, not unlike that of a placenta attachment between mother and child (which is non-self with respect to the mother). Why? In my observations it is because there is a perception, in most people subliminal but if you have meditational experience can be brought to consciousness, of a theatre of war in the body fighting some alien force. This is because cancer is an attempt to build a protective barrier. A bad solution and one attempted only because the person is blindsighted.

Your view is of course the official medical view but I found this is not true. When I resolved some issues with trespassers onto my property, who I realized were involved in the foul game play, I was shocked at how quickly the flu-like symptoms disappeared.. from arguing on the street with them outside my house till I walked back inside my house about 4mins the flu-like symptoms that had plagued me for three weeks were gone. And I was able to effect cancer remission.
Anyway thanks for your reply.
