Seperate the MANUFACTURE of it from the USE of it.
I use it, not manufacture it.
each link provided clearly states that use of IPA is not
carcenogneic, but that the strong acids used in manufacturing it are.
I've quoted the section from each link you provided.

Cancer Hazard
∗ There is an increased incidence of nasal sinus cancer in
workers involved in the manufacture of Isopropyl Alcohol by
the strong acid process. There is no evidence that Isopropyl
Alcohol is a carcinogen.

Epidemiological studies suggested an association between isopropyl
alcohol and paranasal sinus cancer; however, subsequent analysis
suggests that the "strong-acid" process used to manufacture isopropyl
alcohol may be responsible for these cancers [ACGIH 1991].

What we have found is that, according to the best scientific data
available at this time, isopropyl alcohol is not a carcinogen when
used externally. Nasal cancers found in workers in factories where
this type of alcohol is produced are due not to the isopropyl alcohol
itself but to the strong acid used in its manufacture. The "Material
Safety Data Sheet" on Hibiclens® (which contains isopropyl alcohol as
a main ingredient) published by ICI Americas, Inc. states:
The manufacture of isopropyl alcohol by the strong acid process is
associated with paranasal sinus and laryngeal cancer in man. No other
information or data have linked isopropyl alcohol with cancer.1
