Squamous Cell Lung Cancer [An Introduction]

Squamous cell lung cancer is one of the pulmonary neoplasms that are not benign and hence, always-additional clinical emphasis is being given whenever a patient affected with this type of pulmonary neoplasm is presented to the thoracic specialist or the oncologist. It is to be understood that squamous cell lung cancer is epithelial in origin. As for the development is concerned, this type of neoplasm bears no limitations in the growth or spread within the different lobes of lungs.

Metastatic lung cancer

Metastatic lung cancer is the form of cancer that has spread to the lungs from other parts of the body. In a Metastatic lung cancer the cancer in other parts like breast, colon, prostrate, and bladder spread to the lungs through the bloodstream and form cancerous growth in the lungs. This type of cancer in the lungs is called the Metastatic lung cancer. Thus a cancer that has spread to the lungs is said to have metastasized to the lungs.

Staging Non-Small Cell Lung Cancer

This type of tumour may have many stages because it grows more slowly than small cell lung cancer. Occult Stage: Cancer cells are found in sputum at this stage, but no tumour can be detected in the lung. Lung cancer found at this early stage is often cured by surgery. Stage 0: Cancer is found just in a local area of the lung and only in a few of the cells.

Non-small Cell Lung Cancer

Nonsmall cell lung cancer is more widespread than small cell lung cancer, and generally it grows and spreads more gradually. The remaining lung cancers are all non-small cell (NSCLC). There are three sub-types of NSCLC. The cells in these sub-types fluctuate in size, shape, and chemical make-up. Squamous cell carcinoma: About 25% - 30% of all lung cancers are Squamous cell carcinomas. They are linked with a history of smoking and tend to be found centrally, near a bronchus.

Small Cell Lung Cancer

There are three types of small cell lung cancer. These three types include lots of different types of cells. The cancer cells of each of these grow and multiply in different ways. The types of small cell lung cancer are named after the different types of cells found in the tumour and how they look when examined under a microscope: Mixed small cell/large cell carcinoma. Combined small cell carcinoma.

High Blood Pressure - Risk Factors

Risk factors are behaviours or conditions that can increase your chances of developing a disease. For example, high blood pressure is a risk factor for: heart disease, stroke, dementia, congestive heart failure, kidney disease, and, blindness. However, high blood pressure isn’t the only risk factor. For example, there are other risk factors for heart disease and stroke. Most can be modified, though some cannot. The more risk factors you have, the greater your chances of developing disease.

Malignant Hypertension

Malignant hypertension is a medical emergency which is characterised by a severe rise in the blood pressure which cannot then be lowered. It is diagnosed by the presence of advanced retinopathy in the presence of a diastolic blood pressure of over 120 mm Hg. Malignant hypertension is more prevalent in African type people and also more common in smokers. It affects about 1% of those people already suffering with high blood pressure.

Lung cancer

Most lung cancer starts in the cells lining the main air passages, or bronchi. In their cancerous state, these cells lack cilia which are tiny hair like substances which normally catch and remove foreign particles inhaled into the lungs. Mucous in the lungs which is usually cleared by bronchial cilia then becomes trapped, blocking air passages and causing respiratory problems. There are several different types of cancer affecting the lungs; the principal cancers are described below.
