Cancer of the lung is usually due to abnormal growth and development of cells within the tissues of the lungs.

This disorder is responsible for almost 1.3 billion fatalities globally.

The uncontrolled growth of cells accumulates within the lungs and this forms a cancer, which can be completely different from the cells located in the periphery of the lungs.

This growth is regarded as dangerous since it takes the nutrients and oxygen on the healthy cells. In the US, lung cancer overtaken the average amount of deaths due to prostate-related and breast cancer.

The major cause of cancer of the lung includes smoking, too much exposure to radon gas and lengthened exposure to asbestos.

The most prominent symptoms of lung cancer in men and women include: shortness of breath, coughing up blood, ache in the back, arms and chest and repetitive attacks of pneumonia and bronchitis.

Cancer growths are usually located in the right lung more so than in the left lung and there are two basic kinds of the disease:

* Small Cell Lung Cancer or SCLC: This is often considered as the very least common kind of lung carcinoma and the multiplication of this is at an alarming rate. The main reason for this cancer problem is smoking cigarettes.

* Non-small Cell Lung Cancer or NSCLC: This, however, is recognized as the most common type of cancer of the lung and this also includes subtypes of tumors including squamous cell lung cancer, adenocarcinoma, and large cell lung cancer.

To be able to identify cancer stage effectively, the patient will be needed to undergo MRI scans, laboratory testing, bone scans and X-rays.

Positive results from the lab testing are often required to determine if there is metastases in the bone or liver. By using a radiological method, the size of the tumor, as well as spread, can be discovered.

What does lung cancer feel like? This typically is determined by the type of growth and the cancer stage.

The different stages of lung cancer include the following:

Stage I

This is the initial stage of cancer in which the cancer is localized and the lymph nodes are unaffected. During this stage, the patient can easily get treatment method by going through a surgical procedure.

Nevertheless, only 15% of cancer conditions are discovered at its earlier stage. The tumor can get into all the underlying tissues.

Stage II

In the second stage of carcinoma of the lung, the tumor has already spread on the nearby lymph nodes and it has already occupied the chest wall. In some cases, it could already propagate the diaphragm and the external lining surrounding the heart.

Stage III

In this cancer stage, the cancer has now impacted the lymph nodes covering the space in between the heart and lungs. This stage of cancer may also affect the blood vessels.

Stage IV

This stage is regarded when the growth has spread beyond the region of the lungs and to other parts of the body. Surgical treatments may not be considered for the management of this cancer stage, and the patient can only resort to chemotherapy or radiation.

The rate of survival of this cancer stage is less than 10% and apart from the normal symptoms of the disorder, the patient can also experience headaches, difficulty ingesting and vision changes.

It is also possible to search the web for the life expectancy percentage for every stage of lung cancer or talk to your personal doctor.

You can also ask your doctor for additional information with regards to a particular form of cancer, including squamous cell lung cancer symptoms and treatments.
