What is Cancer?
Cancer is a type of diseases that characterized by out-of-control cell growth. There are more than 100 different types of cancer, and each is classified by type of cell that is initially affected.
First of all it is significant to recognize that cancer is not a single illness, there are very many diverse types and mesothelioma is just one type.
Our bodies are made of miniature or tiny building blocks that called cells, cancer is a disease or infection of these cells. Cells from special parts of the body look and work in a different way and millions of new cells are made day by day to replace those lost through old age or wear and tear. all through the body new cells are produced when existing cells divide into 2 and there is generally a perfect balance between those that are dividing and those that are dying. This essential balance is controlled by a very complicated procedure, if control of this procedure is lost it can direct to too many cells being produced which results in a tumour. Most tumours are not cancerous (sometimes described as the benign) and they continue in the area where they first developed. For example: A wart .
The improvement of cancer involves a change in the value of the cells as well an enlarge in the quantity. They become more violent, independent and destructive of normal cells. They are capable to invade surrounding tissues, glands and blood vessels and thus broaden away from where they started to divide and grow. When the cancer cells reach a fresh site they may go on dividing and form a new tumour, this is often referred to as a metastasis or secondary.
What is Mesothelioma?
Mesothelioma is a unusual type of cancer that may take up to 20 years to extend. At present there are three(3) recognized forms of mesothelioma wherein doctors can diagnose patients and these are pleural ,peritoneal and pericardial mesothelioma. In the United Kingdom (UK) about 2500 people in a year are diagnosed with mesothelioma. It is also known as‘malignant’ or ‘diffuse’ mesothelioma.
Mesothelioma is a type of cancer that affects the mesothelium, which is a skinny membrane that lines the inner outside of the chest wall where it is known as pleura, and abdomen, where it is known as peritoneum.
It also surrounds the organs that found within these cavities for example the lung ,heart and intestines.It is far more general to have mesothelioma in chest than in the abdomen, there is about one(1) case of peritoneal mesothelioma to every 12 cases of the pleural mesothelioma.
The pleural lining have two layers: (1)the visceral (inner) layer is next to the lung and (2)the parietal (outer) layer lines the chest wall.
The pleura creates fluid that lubricates the space between two layers, this permits two layers to slide at ease over each other like we breathe in and out.
Pleural mesothelioma causes pleura to thicken. This thickening of pleura might start to press onto the lungs or attach itself to inside of the chest wall. In either case the expansion of lung becomes increasingly restricted by the tumour. Fluid, sometimes several litres, can gather between the two layers of the pleura; this affects the lungs ability to expand and causes the person to feel breathless. This is known like a pleural effusion.
The peritoneum also has two layers like (1)the inner (visceral) layer which is next to the abdominal organs and (2) Outer (parietal) layer which lines the abdominal wall.
Peritoneal mesothelioma causes to peritoneum to thicken and fluid to collect in the abdomen. This compilation of fluid is called ascites and causes abdomen to swell. Since pleural mesothelioma is more general and often spreads to peritoneal cavity, it is sometimes essential to find out if pleural mesothelioma is the crucial cancer.
