– whether from a carefully created
and controlled fever or from hyperthermia
delivered by microwaves, radio frequency
or ultrasound – is increasingly
being used as a cancer treatment.
two theories as to why this might work.
First, a fever within the body produces
a state in which the immune system becomes
hypersensitive, detects that the cancer
cells are not normal and attacks them. It
may be that, if we have a strong immune
system, it is destroying cancer cells every
day but, on occasion, some cells are missed
and cancer develops. In the USA scientists
are experimenting with giving cervical cancer
patients a bio-engineered form of listeria
(not the actual disease) - both it and salmonella
are instantly recognisable by the body as
enemy bacteria – thus hoping to spark
the immune system into rising up to fight
it and the cancer.
