Cancer has a fearsome reputation. Not without reason either. It is a disease that has not yet fully yielded to the skills and intelligence of medical scientists and doctors. And, as if the pain from the disease is not enough, the treatment for cancer, too, inflicts heavy suffering on the body.
Cancer is a disease characterized by uncontrolled and abnormal cell division. Cancer spreads in the body and destroys tissues when the cancer cells travel through the blood stream or the lymphatic system. The runaway growth of cells is caused by mutations to the DNA in the cells that makes the cells unable to control cell division. This mutation can either be inherited or acquired. The mortality rate in cancer depends on the type of cancer and where it develops.
Among cancers, lung cancer is the biggest killer, causing up to 3 million deaths every year worldwide. It affects the above-50 age group population most and is one of the most common types of cancers that occur in the Western countries. The main risk factor for lung cancer is smoking. Cigarette smoke, especially, contains several carcinogens. It is estimated that 80 per cent of all lung cancers are caused by smoking. The role of passive smoking in causing lung cancer is also being recognized by studies.
Another carcinogen that causes lung cancer is asbestos. This substance, which is widely used because of its fire-resistant qualities, causes a rare type of cancer called mesothelioma cancer. In mesothelioma asbestos lung cancer or asbestos cancer, malignant cells develop in the pleura, the outer lining of the lungs and the chest cavity.
The problem with asbestos cancer is that diagnosis is difficult. For one, the symptoms of mesothelioma cancer occur only 30-50 years after the exposure to asbestos. Second, the symptoms of asbestos lung cancer, such as shortness of breath and chest pain, are similar to those of many other medical conditions.
The incidence of mesothelioma asbestos lung cancer has increased in the last two decades. Still it is considered a relatively rare form of lung cancer, because the incidence rate is only 1 per 1,000,000 people. This could be as high as 7-40 per 1,000,000 in the industrialized nations. By contrast, the incidence of lung cancer is 1,000 per 1,000,000.
The common lung cancer treatments include surgery, chemotherapy, and radiation therapy. However, the conventional treatment methods have not been very successful in the case of asbestos cancer, yielding only a median survival rate of 6-12 months after the presentation.
Again, surgery does not have much effect on small-cell lung cancer. A treatment method for lung cancer that has become increasingly popular in recent years is radiofrequency ablation. This technique is especially effective in destroying the cancerous cells inside the tumors. These cells are 'cooked' by inserting a small heat probe into the tumor. This technique is also non-toxic and causes very little pain for the patient.
However, there is hope for the cancer-affected. Scientists are developing new techniques of treatment, such as molecular targeted therapies, for lung cancer. Better and more effective therapies can be expected as scientists and researchers coax out more secrets from the human cells.

Studies show that there is an increase of lung cancer instances among workers exposed to asbestos. In lieu to this, asbestos lung cancer has become one of the most dreaded types of lung cancer. The causes of lung cancer vary. Aside from exposure to asbestos, smoking and air pollution can trigger the onset of the disease. Therefore, avoiding these possible cancer-causing agents is essential for healthy lungs.
If you are in the construction business or employed by an industry that uses products containing asbestos, you may wonder "Are asbestos fibers visible to the eye"? Generally asbestos fibers are too small to be seen by the naked eye. Asbestos becomes dangerous when it has broken down into small fibers and is inhaled. It is nearly impossible to detect the presence of asbestos without taking the material to a lab for testing. A lab technician will put the material under a microscope to search for asbestos fibers. Asbestos does not cause an immediate reaction. It will not cause you to cough, sneeze, or your eyes to water. You cannot see, smell, or taste asbestos.
Cigarette smoking is probably the most closely related link to developing lung cancer. A person who smokes two packs or more of cigarettes per day has a one in seven chance of developing lung cancer. Those that smoke one pack of cigarettes per day have a twenty-five times greater chance of developing lung cancer than a non-smoker. In addition, those people that smoke a pipe or cigar have a five times greater chance of developing lung cancer than a non-smoker.
Asbestos is a problem in homes that a lot of people have heard about, but few understand. It is a mineral fiber capable of standing up to intense temperatures, added to a variety of products before people realized it was dangerous. It is now considered toxic waste, but previously was used in a some building equipment due to its low cost and heat resistance. In the 1970s, the Environmental Protection Agency instituted a decade-long phase out of its use, but many older homes still contain the material. Asbestos is now considered a liability, and is sometimes the determining factor in whether a buyer will purchase a home or whether a mortgage company will provide a loan. If you suspect asbestos
It would almost seem like a given in this day and age that people would know and understand that smoking greatly increases the risk of lung cancer. Secondhand smoke has even been linked with increased lung cancer risks. Even were a person to never smoke a cigarette or be subjected to secondhand smoke, the possibility of lung cancer remains very real. But smoking cigarettes is nothing short of adding more bullets to a gun being used to play Russian Roulette-eventually, the odds of getting lung cancer will become impossible to ignore.
Covering our internal organs, the mesothelium is a protective tissue that lubricates and protects our internal organs thus allowing our lungs to breathe and our heart to contract or expand without any discomfort for us.This fine tissue, the mesothelium enables breathing and heart beating therefore being essential to our survival.
Among the various type of cancer deaths, lung cancer is responsible for 29 percent of that. Hence, you can begin protecting yourself now by arming yourself with the general facts on lung cancer before it's too late.
