Difference Between Lung Cancer and Mesothelioma

Many people ask this question, to which the answer is both simple and complex. Mesothelioma is often talked about as though it is a form of lung cancer. It is not. Mesothelioma is a cancer of the mesothelium, the lining or membrane, around an organ, such as a lung, abdomen, or the heart. Mesothelioma is a diffuse malignancy. It invades a tissue area as a large number of interlocked tumors and the boundaries between malignant tissue and healthy tissue are blurred and, eventually, dissolved. This is the primary reason that mesothelioma remains so difficult to treat. The large extent of malignant tissue makes complete surgical resection very difficult.

While lung cancer works differently. It arises within the lungs themselves and is characterized by individualized tumor masses. Even for people with multiple masses, the tumors generally possess clear boundaries. The tumors can grow quite large and in its late stages and most aggressive forms,  Lung cancer involves the lung tissue and airways, which is contained entirely within the pleural lining and does not involve the pleura. Where other organs are involved the mesothelial lining has other names, such as peritoneum for the mesothelial lining of the peritoneum (abdominal cavity), and pericardium for the lining around the heart. Lung cancer is just as deadly as mesothelioma. However, it is much more amenable to treatment than mesothelioma is.

There are other differences between lung cancer and mesothelioma as well. While asbestos exposure is a causative factor for both disorders, it is the only known cause of mesothelioma while lung cancer can be caused by other agents—including cigarette smoking.

So the differences is clear now. Mesothelioma is a cancer that occurs in this lining. It is caused by asbestos being inhaled into the lungs. From their, the asbestos fibers are absorbed into the body. How exactly they get into the mesothelium is unknown, but they clearly due. Mesothelioma can spread throughout the entire body core or remain in a particular area. If caught very early, treatment options exist. If caught late, it is rarely survived.

So, how do Mesothelioma and lung cancer get confused when it comes to asbestos exposure? Well, Mesothelioma often occurs in the mesothelium lining around the lungs. Although not technically lung cancer, once can see how the two would get confused. Still, it is important to remember that each is unique and calls for different treatments.

The Relationship Between Lung Cancer and Mesothelioma

Lung cancer is the most common cause of death due to cancer in both men and women throughout the world. Lung cancer is a result from an abnormality of cells in the body. Lung cancer is sometimes called "bronchogenic cancer," or it may be described by its particular histologic type, that is the type of tissue that is diseased.

Lung cancer is predominantly a disease of the elderly; almost 70% of people diagnosed with lung cancer are over 65 years of age, while less than 3% of lung cancers occur in people under 45 years of age.

Everybody knows that cigarette smoking is the most closely related link to developing lung cancer. As a matter of fact, the earlier one begins smoking and the higher the number of cigarettes one smokes, the higher the chances of getting lung cancer. Exposure to asbestos, radiation, and pollution are also some of the other causes of lung cancer.

Asbestos exposure is one of the cause of lung cancer and mesothelioma.  Asbestos is a bunch of naturally occurring minerals that are resistant to fire and chemical substances. They are fibrous mineral forms of impure magnesium silicate and located in fire-proofing materials, electrical insulation, cement, shingles, acoustic and decorative ceiling plaster, and additional construction materials. When repairing, removing, or disturbing asbestos-containing supplies, tiny asbestos dust will be dispersed into the open air. Asbestos separates into fine silica fibers that become trapped in the tissues of the lungs. 

Mesothelioma is inextricably linked to asbestos exposure. There are no reported cases of mesothelioma in people who were not exposed to asbestos either in the workplace or through their environment. 

Mesothelioma Peritoneal Treatment

Peritoneal mesothelioma is a rare form of asbestos cancer that is extremely difficult to diagnose and treat, and which in most cases, leads to death. 

People diagnosed with peritoneal mesothelioma usually first see their doctor with a symptom for abdominal swelling. There are another possibility caused of abdominal swelling besides peritoneal mesothelioma, such as cirrhosis of the liver. It can take some time and a battery of medical tests to correctly identify peritoneal mesothelioma. 

Once the peritoneal mesothelioma is correctly diagnosed, it is difficult to predict how aggressive it will be in an individual patient, because this variant of mesothelioma has shown a wide spectrum of behavior. A patient may have recurring and severe bouts of lower abdominal pain, or not. The cancer could also metastasize from the peritoneum to lymph nodes. 

A peritoneal mesothelioma diagnosis is difficult at best. After confirming a history of asbestos exposure the doctor will run numerous tests to confirm or deny the suspicion of peritoneal mesothelioma. The first of these tests usually involve imaging of the suspected site. Traditional x-rays can be used to check the abdominal cavity for suspicious growths but MRIs and CT scans will offer a more detailed view.

Localized treatments treat only the original cancer site by either surgery or radiotherapy. When peritoneal mesothelioma is detected early on,  a peritonectomy surgery would help. However, the symptoms are usually detected only in the most advanced stages because of the gradual development of symptoms. Complete removal of the caner through surgery is doubtful even in the earliest stages of the disease. The first 30 days following surgery are crucial. Unfortunately, the post surgery death rate for this operation is very high. Many patients do not make it through the procedure. With this in mind, many medical centers do not choose surgery as a viable treatment option plan at this time.

When the cancer is still localized at its point of origin, doctor may will undergo regional chemotherapy . This option treatment is employed in both early and late stages of the disease using anti-cancer drugs. The drugs are injected directly into the abdomen. Patients undergo weekly or biweekly treatments depending upon the specific drugs used.

A second type of treatment known as systemic treatments are used when the cancer has metastasized. Systematic treatments are implemented in either earlier stages or late stages of peritoneal mesothelioma.

Since peritoneal mesothelioma often remains dormant for years, the cancer is usually detected in its end stages. At this point patients are too ill to handle intensive chemotherapy. Doctors choose non-aggressive palliative care treatments at this time. Treatment goals are concentrated on remedying pain, discomfort and weight loss rather than attacking the disease head on. One type of pain common in the late states of this disease is caused by fluid buildup inside the abdomen. Doctors will attempt to reduce the pain and discomfort by draining the excess fluid through a procedure called abdominal paracentesis.

3 Types of Asbestos Lung Disease

The chances of asbestos lung disease were raised by 700% compared to people who are not exposed theasbestos. An increasing number of people are found to be afflicted with lung cancer in the recent years. A careful look shows that many of these lung diseases that people have are directly related to asbestos.

There are 3 main types of asbestos-related lung illness. The first is Asbestosis, second is disease in the lung lining (pleura) and the third one is the lung cancer. We will differentiate these three types of lung diseases. Asbestosis is a chronic inflammatory condition that affects the tissue of the lungs caused by inhalation and severe exposure of asbestos. In short, is a widespread scarring in the lungs.

The second type of lung disorder caused by asbestos is the disease on the lung lining or in medical terms, it is called pleura. This disease shows signs and symptoms resulting in the hardening or thickening of the tissue lining.

The last is the lung cancer which is either located in the internal portion of the lungs or the outer lining (pleura).

Asbestosis Treatment : How to Treat The Disease

Asbestosis is a disease caused by Asbestos exposure. This is a respiratory illness that affects the lungs. It's not always detected, as the symptoms are similar to those of generally getting older, and being slightly overweight.


If any of the symptoms of asbestos exposure were found, then you clearly need
treatments. The treatments for asbestos vary depending on the type of disease the person contracts. There are many options and some are disease-specific, which means that the treatment option is only applicable to a certain disease.


At present, there is no cure for asbestosis. The lung tissue that has been scarred cannot be repaired but further damage can be prevented by ending asbestos exposure. Treatments are available to manage the symptoms but not the disease. It is important, though, to stop exposure to asbestos fibers as well as to dust, smoke and other irritants.


If you are diagnosed with asbestosis, doctor will likely instruct you on how to an asbestos bronchial drainage which leads to excessive coughing to remove unwanted materials in the bronchi. He generally will recommend the use of pain killers, bronchodilators and antibiotics for relieving the symptoms. If lung function has been greatly affected, oxygen therapy might be required as well. Bronchodilators may help the shortness of breath. It relax the airways so that more air can be inhaled into the lungs. The asbestosis patients may suffer excessive lung scarring, hence a postural drainage procedure might be employed to remove these secretions in order to improve lung capacity. Oxygen supplementation could be administered for more sever cases of asbestosis.


People diagnosed with asbestosis, have to limit the exposure to asbestos and smoking. The latter contributes a lot to contracting inflammatory diseases. The first line of defense is to give you antibiotics to resolve other respiratory diseases. Those who continue to smoke even after being diagnosed with asbestosis are more likely to develop lung cancer.


The symptoms of asbestos exposure can also be relieved to some extent by following alternative healing therapies such as acupuncture, meditation, deep breathing exercises, herbal remedies and homeopathy. If you have been exposed to asbestos in the past, it is advisable to have yourself diagnosed by a surgeon who specializes in asbestos exposure cases. Early detection is your best protection against diseases caused by asbestos exposure. With an early diagnosis and asbestos exposure treatment, you can increase your chances of containing the disease.

Symptoms Asbestos Exposure : Know The Signs

The symptoms of Asbestos exposure is a "red flag" that should be immediately sent an individual straight to a physician if any symptoms are diagnosed. It is better if the physician is familiar with Asbestos disease, because the sooner that an asbestos disease is identified, the sooner the treatment will begin. This is particularly important for cancers caused by asbestos exposure.

Many studies reported that the combination of smoking and asbestos exposure is particularly hazardous. Smoking seems to increase the frequency and/or the rate of progression of asbestosis, possibly by preventing the efficient elimination of inhaled fibers from the airways. Smokers who are exposed to asbestos have a risk of developing lung cancer that is greater than the individual risks from asbestos and smoking added together.

Most asbestos exposure symptoms don't begin to manifest until 15-30 years after initial inhalation. With the lack of early warning signs, it makes that wait all the more dangerous. Normally, you won't even notice anything until the cancer has actually gotten to a life-threatening stage.

Short term exposure to asbestos may show up symptoms like, shortness of breath. In such cases, one can experience the short term asbestos exposure symptoms like, abdominal pain, chest pain and irritation of the skin and the mucus membrane, along with shortness of breath. Another symptoms can be spotted are :

• Shortness of breath, hoarseness or wheezing
• A persistent cough that gets worse over time, or a change in cough pattern
• Blood in the sputum (fluid) coughed up from the lungs
• Difficulty in breathing
  
• Pain in the abdomen
• Difficulty swallowing
• Unexplained weight loss
  
• Fatigue or anemia
• Crackling sound in the lungs during inhalation
• Swelling of the neck and/or face
• Loss of appetite
• Coughing up blood
• Wheezing
• Nausea

Having one or more of these symptoms does not mean that you have an asbestos related health problem, but it could be some other problem not related to Asbestos at all, but it is advisable to get it checked by your physician immediately.

You may be asked to get X-rays of the chest removed, or a CT scan done, or if the case is found to be of severe nature, a lung biopsy to detect the asbestos fibers could be performed.

Visiting the physician once you are aware of any symptoms of asbestos exposure could not just prolong, but possibly even save your life.

Asbestos Exposure : The working's man killer

As what have been written about Mesothelioma on the previous post, the most harmful cause is Asbestos. Asbestos is a natural fiber that has been used extensively in myriad industries for the last century.

Asbestos can be found in various sizes and shapes around the world.

It has three most common types : white asbestos (chrysotile), brown asbestos (armosite) and blue asbestos (corcidolite). All three of these silica have been associated with lung diseases - both non-cancerous as well as cancerous.

Asbestos is much used in the construction of many buildings and places of business. Asbestos is prized for its heat and flame resistance, soundproofing, and insulating properties, it also poses significant threats to human health. Unknowing workers worked in these structures each day not know that there was danger lurking in the walls and ceiling. The building and construction industry uses Asbestos for strengthening cement and plastics as well as for heat insulation, fireproofing, and sound absorption. The shipbuilding industry has used asbestos to insulate boilers, steam- pipes, hot water pipes, and nuclear reactors in ships.

Those who worked at any one of these jobsites were likely exposed to a number of asbestos-containing products and are now at risk of developing mesothelioma and other asbestos-related illnesses. When people are exposed to asbestos then three different types of lung diseases can develop: 1) asbestosis; 2) lung cancer; and 3) disease of the pleura - the lining of the lung.
