The term latency period is used to describe the period of time between exposure to a potential disease-causing agent and the time the disease becomes apparent. According to most experts, in the case of mesothelioma the latency period ranges from 20 to 50 years after initial exposure to asbestos occurred, though there have been instances when the time period was shorter or longer.
Due to the long latency period associated with the cancer, those exposed to asbestos during the 1950s, '60s and '70s are beginning to demonstrate mesothelioma symptoms today, decades after they were exposed to asbestos.
Living During the Latency Period
While no one should spend their days dwelling on the fact that they could someday develop an asbestos-related disease, there are some things that can be done to aid in early diagnosis if mesothelioma is indeed present.
The most notable development in the last few years is the mesothelioma blood test known as Mesomark. Approved by the FDA in 2007, this simple test measures a particular cancer biomarker and can catch mesothelioma in the early stages of development. The blood test is not available everywhere but if you wish to undergo testing, asking your doctor where you may take advantage of the test may aid in early detection.
Those exposed to asbestos run the risk of developing asbestosis or mesothelioma and may wish to schedule yearly chest X-rays to check for any suspicious signs of disease. If a doctor determines there may be a concern after the X-ray, further imaging tests such as CT scans or MRIs may be recommended. A biopsy may also be requested to test for the presence of cancerous cells.
