What is the Difference Between Lung Cancer and Mesothelioma?

Thursday, September 22nd, 2011

A person who has been diagnosed with mesothelioma, or know someone who is, may have trouble understanding the cancerous condition and how it is distinct from other forms of cancer—in particular, lung cancer. The two forms of cancer are actually quite different. So what, exactly are the differences and what impact do those differences have?

One important difference between lung cancer and mesothelioma is how the two forms of cancer develop. Mesothelioma develops as an interconnected network of many tumors over a large area of tissue. Over time, the boundaries between healthy and cancerous tissue become indistinguishable. The structure and growth pattern of this form of cancer may dramatically limit options for patients receiving mesothelioma treatment. In many cases, removing malignant tissue becomes very difficult, if not impossible, because of the number of masses and the size of the affected area. Radiation works best on smaller areas of tissue, limiting its effectiveness with mesothelioma. Unfortunately, in many cases chemotherapy may not be sufficient to treat the large number of tumors. Eventually, these networks of masses overtake the tissue, limiting the movement of that tissue. Unfortunately, they tend to develop long before they become noticeable to the victim. By the time symptoms from the tumors are noticed, it is often too late for effective treatment.

The structure and growth of lung cancer is very different from that of mesothelioma. With lung cancer, tumors grow as distinct, individual masses, and boundaries of these masses are very clear. This is true even when there are several masses. While these isolated tumors can become very large and just as life threatening as mesothelioma, treatment may be more effective. Because the masses are so distinct, when caught early enough, they can sometimes be surgically removed. Radiation and chemotherapy tend to work better in these cases as well.

Other differences between these two forms of cancer include their rarity and their causes. In general, the incidence of mesothelioma is much smaller than that of lung cancer. Likewise, the causes of lung cancer can vary and overlap (including exposure to pesticides, heavy metals, pollutants, radon, and/or smoking), while mesothelioma causes are generally linked to asbestos exposure.

While there are many differences between these two forms of cancer, the early warning signs (when detected) of lung cancer and mesothelioma may be very similar. If you or someone you know is experiencing unusual and persistent respiratory symptoms, contact a doctor, as early detection may have a very real impact on the effectiveness of treatment.

Asbestos Facts

Wednesday, July 14th, 2010

Chances are, if you’ve found this blog, you already know some asbestos facts.  Chief among them is that exposure to it can cause mesothelioma.  That’s why you’ll often see the two linked when you read articles about mesothelioma settlements and the like.  But do you know how the two are linked?  Below are some facts about this mineral, and what it can mean for those who are (unfortunately) exposed to it.

Asbestos is a mineral that is found naturally in a fiber-like form.  Due to this form, it’s very lightweight and is a very good insulator and a poor conductor.  These properties have caused it to be historically prized as a construction or industrial material, and it’s been used as insulation for pipes, boilers, buildings, and ships.  Furthermore, when asbestos is mixed with concrete, it increases that concrete’s tensile strength, which means less concrete needs to be used and transported.

Asbestos can be categorized by the two forms (sepentine and amphibole) that it comes in.  Amphibole asbestos can be further broken down into different types, which include crocidolite and amosite.

While asbestos can be found all over the world, the historical leader of mining production for the mineral has been Canada.  Today, other nations, including Russia, Australia, China, and South Africa all produce large quantities of asbestos and compete with Canada.

Back to the previously mentioned fiber-like form of asbestos: when the mineral is disturbed, the fibers very easily break down into dust clouds of miniscule particles which can become airborne.  From there, they’re very easily inhaled or swallowed.  The body, unfortunately, cannot break down the inhaled fibers.  After many years of dormancy, these fibers can start to eat away at the lining of the lungs, a devastating process which can cause many diseases.  Chief among these are lung cancer, asbestosis, and mesothelioma.

That, right there, is the sad connection between the two.
