Why Mesothelioma Cases Occur in Palo Alto
Palo Alto's asbestos legacy is tied to its world-renowned institutions. Stanford University, founded in 1891, has hundreds of buildings constructed between the 1900s and 1980s that used asbestos in insulation, fireproofing, pipe lagging, floor tiles, and laboratory construction. Maintenance workers, custodians, tradespeople, and construction crews who worked on campus buildings faced sustained asbestos exposure.
The VA Palo Alto Health Care System is one of the largest VA medical centers in the nation. Its buildings, constructed primarily in the mid-20th century, used asbestos extensively in pipe insulation, boiler rooms, floor tiles, ceiling materials, and HVAC systems. Hospital maintenance workers, engineers, and renovation crews were exposed to asbestos throughout the facility's history.
The 20-to-50-Year Latency Period
Mesothelioma has a latency period of 20 to 50 years. A worker exposed to asbestos at Palo Alto facilities in the 1970s may only receive a mesothelioma diagnosis in 2025 or later. This is why Palo Alto continues to produce new mesothelioma cases decades after asbestos use was restricted.
Varian Associates (now Varian Medical Systems), founded in Palo Alto in 1948, manufactured medical and industrial equipment using asbestos-containing components. Workers assembling linear accelerators, klystrons, and other radiation equipment handled asbestos insulation, gaskets, and thermal materials. Hewlett-Packard, also founded in Palo Alto, operated early manufacturing facilities where asbestos was present in building materials.
Palo Alto's older commercial district, residential neighborhoods, and school buildings all incorporated asbestos-containing materials during their original construction. The Stanford Research Park, one of the nation's first technology parks, houses buildings from the 1950s and 1960s that contained asbestos in their original construction.
Palo Alto's Asbestos Legacy by the Numbers
Stanford University has over 700 buildings, many constructed before asbestos regulations. The VA Palo Alto Health Care System serves over 85,000 veterans annually. Varian Associates has operated in Palo Alto since 1948. California allows only 2 years from diagnosis to file a mesothelioma claim. Documenting your asbestos exposure history is a critical first step.
