The Real Facts about Cancer

There is no doubt that cancer is known for its fearsome reputation. There is reasons for its reputation. This is a disease which has not yet fully yielded to the the abilities and intelligence of doctors and medical scientists. And, as though the torment from the disease is not enough, the treatment for cancer, too, causes heavy suffering to the human body.

Cancer is an illness characterised by uncontrolled and abnormal division of cells. Cancer develops in the body and destroys tissues when the cancer cells travel through the lymphatic system or the bloodstream. The run-away growth of cells is prompted by alteration to the DNA. This mutation can neither be genetic or obtained.

Lung cancer is the biggest killer among the cancers. It causes up to 3 million deaths yearly worldwide. In Australia, lung cancer is the 5th most common type of cancer but it is the most common death cause. It also responsible for nearly one in five deaths by cancer in Australia. Lung cancer impacts mostly the above-50 age group population and is one of the most frequent types of cancers that occur in the nations. Smoking is the primary risk factor for lung cancer. Cigarette smoke, particularly, consists of carcinogens. Approximately 80 percent of all lung cancers are generated by smoking. Studies are also recognising the role of passive smoking in causing lung cancer.

Asbestos is another carcinogenic substance that causes lung cancer. This substance, that is used massively, is preferable because of its quality of being resistance to fire, causes a unfamiliar kind of cancer called mesothelioma cancer. In mesothelioma asbestos lung cancer or also called asbestos cancer, the cancerous cells develop in the pleura, the lungs outer lining along with the chest cavity.

The issue with asbestos cancer is that it is difficult to be diagnosed. For one, the mesothelioma cancer symptoms happen only 30-50 years after the first exposure to asbestos. Second, the asbestos lung cancer symptoms, for example, shortness of breath and chest-pain, are the same like those of numerous other medical conditions.

The incidence of mesothelioma asbestos lung cancer has become greater in the last two decades. Still the cancer is considered a fairly uncommon kind of lung cancer since the incidence rate is only one per 1,000,000 people. This might be as high as 7 until 40 per 1000,000 in the industrialised countries. In contrast, the incidence of lung cancer is approximately 1,000 per 1,000,000.

The common lung cancer remedies involve chemotherapy, surgery, and radiation therapy. However, the methods of the conventional treatments have not been really effective when it comes to asbestos cancer, contributing only a median survival rate of 6 to 12 months after the presentation.

Additionally, surgery does maybe not have much impact on small-cell lung cancer. A radiofrequency ablation is a medical care for lung cancer which has become increasingly well-known in current years. This method is especially successful in destroying the malignant cells inside the tumours. These cells are 'cooked' by putting a small heat probe into the tumour. This method is also non-toxic and gives patient very tiny pain.

However, there is hope for the cancer-afflicted. Scientists are undertaking new techniques of treatment, for example molecular therapies, for lung cancer. Patients now can expect better and more effective therapies as researchers and experts coax out further secrets from the human cells.
