Common Symptoms of Lung Cancer

Lung cancer is one of the most common cancers in the world. It is the leading cause of cancer death among men and women in the United States. Cigarette smoking causes most lung cancers. A greater number of cigarettes they smoke daily newspapers and the younger you start smoking, the greater the risk of developing lung cancer. Exposure to high levels of pollution, radiation and asbestos can also increase the risk.

Common symptoms of lung cancer include:

  1. A cough that does not go away and worsens over time
  2. Constant chest pain
  3. Cough with bloody sputum
  4. Shortness of breath, wheezing or hoarseness
  5. Repeated problems with pneumonia or bronchitis
  6. (more…)

Lung Cancer: What and how (II)

Lung Cancer

There are two main types of lung cancer: non-small lung cancer cell (or non-small) and small cell (or microcytic). The term “small cell” refers to the size and shape of cancer cells as seen under the microscope. Non-smal lung cancer cell originates in the epithelial cells and is the most common type. Lung cancer begins small cell in the nerve cells or hormone-producing cells.

Each of these types of lung cancer grows and spreads differently, and each requires a different treatment. It is therefore important to find out what type of lung cancer a person has to apply the appropriate treatment.

Once the malignant lung tumor begins to grow, it is possible that cancer cells detach. These detached cells can be transported by the blood or lymph. When a cancer cell is apparent from its place of origin and moves to a lymph node or to a distant part of the body through the bloodstream, and there starts to split and form new tumors, we say that the tumor because distant metastases, has metastasized. We then say that the patient has a cancer then spread, with metastatic cancer.

The lymph flows through tubes called lymphatic vessels that drain into a “collecting stations, lymph nodes, found in the lungs (around bronchi) in the center of the chest (mediastinum) and other body parts. The natural flow of lymph from the lungs is toward the center of the chest, which explains why lung cancer often spreads to there.

Types Of Lung Cancer

Friday, March 5th, 2010

Lung cancer is classified by the type of cell that produces the tumor. 90% are small cell or non-small cell. The remaining 10% is composed of very rare types such as mixed carcinoid or neuroendocrine tumors.

Furthermore, the lung is a very frequent metastasis. But these are not true tumors of the lung, but plantings of cancers of other organs, such as the breast or intestine.

Small Lung Cancer Cell (microcytic)
It is named after the cell size view microscope. It is almost invariably associated with smoking and it is estimated that about 20% of all cancers are small cell. They multiply rapidly and can form large tumors, plus their ability to spread to other organs is increased. The small cell is almost always a very aggressive tumor.

Metastases tend to affect the following organs: lymph nodes, bone, brain, adrenal glands and liver. The primary tumor usually originates near the bronchi and spreads into the center of the lungs.

Non-small Lung Cancer Cell
This cancer accounts for almost 80% of all lung cancers. It spreads more slowly than small cell and occasionally may occur in nonsmokers.

What Is Lung Cancer?

What Is Lung Cancer?

Cells are the smallest living units of the human body. One function is to reproduce and die when no longer useful. This process is very neat, in time and space, so there is always that allows the appropriate number of cells for each stage of life.

When this multiplication of cells occurs in an uncontrolled manner, forming lumps. These masses are called tumors.

There may be benign and malignant tumors. Benign tumors are those that do not spread to other areas and do not compromise a person’s life.

Malignant tumors often spread to other parts of the body and cause damage to body tissues and organs and can even cause death of the person.

Malignant cells can move through the lymph or blood and reach anywhere in the body causing a second tumor, called metastatic, because it is the first originated.

Lung cancer is an abnormal growth of lung cells. The disease usually occurs on the inner walls of the bronchi, and growing up can obstruct the airway and impair breathing. For this reason, generally produces shortness of breath, breathlessness and fatigue.

There are two main types of lung cancer: small cell cancer or small cell and non small cell cancer (non small or bronchogenic).
