Mesothelioma is a type of cancer that is 99% attributable to a person's having been exposed to asbestos. It could be that you had a job years ago in which you were exposed but won't begin to show symptoms until 20 to 50 years later. Occasionally a case will be diagnosed in less than 20 years, but that isn't the norm. You may not even realize you were exposed to asbestos, and the initial symptoms can be as general as chest or back pain. Anyone who was working prior to the mid 1970s needs to explore the possibility that he or she could have been exposed to asbestos. If this is the case for you, then you'll need to watch out for the development of lung cancer for the rest of your life.

Mesothelioma patients have been diagnosed as having cancer cells surrounding their lungs or abdominal organs or inside their ribcages. While even a little exposure to asbestos could cause the disease, it's far more likely to occur in people who were exposed over longer periods of time. It's real possible that you aren't even aware that you were ever working around asbestos, because it was common for employers back then to withhold from their employees the information that was coming out regarding asbestos exposure. Some examples of people who may have been innocently exposed prior to the 1970s include construction workers or those who were in the Navy.

Prior to the 1970s asbestos was widely-used in many different applications. Once the reports of the health risks involved in its use started to be made public, this use of asbestos was curtailed. Before that time, however, almost every type of insulation contained asbestos, such as that used to insulate pipes, do fire-proofing, and in boilers. Types of plasters, cements, and joint compounds that came in powdered form and were intended to insulate were also full of asbestos. Since the powders caused a lot of dust, employees who breathed the air while using them were particularly vulnerable to asbestos exposure.

People who worked in the following occupations prior to the mid 1970s need to be alert for the symptoms of Mesothelioma: * Paper mills * Brake and clutch shoe manufacture * Boilermakers * Electrical and carpentry workers or bricklayers * Insulation - manufacture or installation * Steel refineries and other steel industries * Shipyard workers * Maintenance workers

Even if you did work in any of these occupations, that's not a sure sign you're going to come down with Mesothelioma. However, it does put you at a higher risk, and you should let your physician know that you were exposed. He may recommend that you take some tests in order to determine if the asbestos is having any effect on you. He may want to do a complete physical, have x-rays taken of your chest and abdomen, and ask you to take pulmonary function tests. In some cases CT scans or MRIs are advisable. All of this testing may well find no evidence of Mesothelioma, but at least you'll know for sure which can be a relief.

If the time comes when you're diagnosed with Mesothelioma, one of the first things you'll want to do is to hire a lawyer who specializes in cases involving the disease. He will be able to evaluate your claim and file a suit against your employer seeking damages if it can be proven that there was any negligence on the part of your employer in withholding information or not providing the safety equipment you needed.
