Probably not. Fiberglass has been studied for carcinogenicity specifically based on the experience with asbestos: https://connect.mayoclinic.org/discussion/fiberglass-insulat... ("Fibers deposited in the deepest parts of the lungs where gas exchange occurs are removed more slowly by special cells called macrophages. Macrophages can engulf the fibers and move them to the mucous layer and the larynx where they can be swallowed. Swallowed fibers and macrophages are excreted in the feces within a few days.
Synthetic vitreous fibers deposited in the gas exchange area of the lungs also slowly dissolve in lung fluid. Fibers that are partially dissolved in lung fluid are more easily broken into shorter fibers. Shorter fibers are more easily engulfed by macrophages and removed from the lung than long fibers.").
We also have been unable to find clear evidence of health harms in longitudinal studies of fiberglass manufacturing workers: https://www.atsdr.cdc.gov/ToxProfiles/tp161-c2.pdf ("Studies of workers predominantly involved in the
manufacture of fibrous glass, rock wools, or slag wools have focused on the prevalence of respiratory
symptoms through the administration of questionnaires, pulmonary function testing, and chest x-ray
examinations. In general, these studies reported no consistent evidence for increased prevalence of
adverse respiratory symptoms, abnormal pulmonary functions, or chest x-ray abnormalities; however, one
study reported altered pulmonary function (decreased forced expiratory volume in 1 second) in a group of
Danish insulation workers compared with a group of bus drivers.").
