In some oils there are PAHs polyaromatic hydrocarbons and these have
been linked to some forms of cancer
https://en.wikipedia.org/wiki/Polycyclic_aromatic_hydrocarbon Then
reading about Creosot https://en.wikipedia.org/wiki/Creosote I found
there is difference in chemical properties between coal-tar and wood-tar
Creosot and I also expect difference in chemical properties between
mineral oil and vegetable oil.
Expect food oil to be relatively harmless also then used as a cutting
fluid, no rust and does not freeze during winter. Maybe bacterial growth
might be a problem but in such case I could kill them by heating
regularly. Do not freeze during winter is an important future for me as
is now.

I understand the problem has been that soluble cutting oil tends to
drench the operator at waist level (on older machines which do not
have total enclosures). That led to a noted connection between cancer
and soluble oil.
I don't know of any link between neat cutting oil and medical
conditions, but it is an oil, so the usual hazards apply.
I have serious reservations about the current fashion for atomised
mist spray coolant, which I believe to be a real danger to the lungs
and possibly the eyes, nose and mouth. I have not seen any medical
studies on this, but atomised fluids of all sorts are generally a bad
idea.
Just my opinion.
