Do not panic if you are exposed to asbestos. The illnesses associated with asbestos exposure are rare. If you are concerned about exposure, talk to your doctor, especially if you are having any respiratory symptoms, such as coughing or difficulty breathing. They may recommend imaging to get a view of the insides of your organs and determine if scarring or growths are present.

According to the National Cancer Institute, asbestos-related diseases can take anywhere from 10 to 40 years for symptoms to appear. The health risks increase with prolonged and heavier exposure. Risk factors also include:

Amount of exposure
Chemical makeup, size, and shape of the asbestos fibers
Length of time a person is exposed to asbestos
Genetic factors
Source of exposure (direct exposure or secondhand exposure from someone directly exposed)
