Mesothelioma Cancer: Causes, Symptoms, Statistics

What is Mesothelioma?

Mesothelioma-cancer

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.

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.

How many people die from mesothelioma?

  • Approximately 2,300 people died from mesothelioma in UK in 2010.
  • Over 8 in 10 mesothelioma deaths in UK occur in men.
  • Mesothelioma death rates in UK have increased by a fifth in women in the last 5 years, but have remained fairly constant in men.
  • Because of changing patterns of asbestos disclosure, the number of mesothelioma deaths is expected to peak in 2016 and decline rapidly thereafter.

How common is mesothelioma?

  • Mesothelioma accounts for below 1% of all cancers diagnosed in UK.Mesothelioma Country
  • In UK in 2010, around 2,500 people were diagnosed with mesothelioma, that is around  7 every day.
  • Mesothelioma is approximately 5 times more common in men than in women. In 2010 there were  about 2,100 cases in men and about 430 in women.
  • About 9 in 10 mesothelioma cases occur in people aged 60 and over.
  • Mesothelioma occurrence rates have increased almost four-fold since the early 1980s.

What are the main causes of mesothelioma?

  • Most cases of the mesothelioma are caused by the past occupational exposure to asbestos.
  • Asbestos is an insulating substance that was extensively used in many industries in the UK from the 1950s up until the mid-1980s, including shipbuilding and construction and where asbestos lagging was fitted or asbestos board was sawn.
  • The use of brown and blue asbestos was banned in UK in 1985. A complete ban on the use of asbestos products was launched when white asbestos was banned in UK in 1999. But workers in several occupations may still come in to contact with asbestos-containing materials that installed before these dates and regulations affect.
  • Mesothelioma symptoms may not come into sight for more than fifty years after exposure to asbestos

Mesothelioma Symptoms
Those afflicted with Mesothelioma may not in attendance symptoms until many years after exposure. General Mesothelioma symptoms such as:

  • Weight loss.
  • Difficulty in swallowing,
  • Pain in abdomen or chest,
  • Flu-like symptoms,
  • Fluid in the lungs, and
  • Respiratory complications

 

Mesothelioma Key Facts and Statistics

  • Mesothelioma is a cancer that arises from abdominal cavities or the cells lining the chest.Cancer
  • Mesothelioma in general results from exposure to asbestos.
  • When mesothelioma have an effect on the chest, the doctor may look inside the chest cavity with a unique instrument called thoracoscope.
  • When mesothelioma have an effect on the abdomen, the doctor may look inside the abdomen with a unique tool called a peritoneoscope.
  • Mesothelioma is diagnosed by the biopsy.
  • The outlook for the patients with mesothelioma depends on how early the disease is detected and how firmly it is treated.
  • Mesothelioma develops in three key HISTOLOGIC types: Epithelial, Sarcomatoid and Biphasic.
  • Over 2,000 new cases of the mesothelioma are diagnosed each year.
  • The first diagnosis or analysis of mesothelioma that was decisively linked to asbestos exposure was made in 1964.
  • The number of mesothelioma cases is supposed to peak worldwide around 2020.
  • More than 50% of patients can guess to be involved with the emerging clinical trials.
  • Since 2011, there have been over 175 clinical trials conducted related to mesothelioma.
  • Additional asbestiform minerals for example erionite have been linked to mesothelioma. In Turkish village of the Tuzkoy, more than half of the villagers have died of respiratory malfunctions together with mesothelioma.
  • Patients in general experience a latency period of 25 to 50 years after primary exposure before symptoms arise. Less than 1 % of patients have a latency period shorter than 15 years.
  • Around 14 to 30 people out of each million will be affected by mesothelioma each year.
  • The National Institute of Health (NIH) guesses that is 11 million people were exposed to asbestos between 1940 and 1978.
  • After treatment, approximately 50 % of patients will experience a life span of 8 to 18 months. About 30 percent or more have a chance of living five years or longer.
  • Males are 4 times more possible to be diagnosed with mesothelioma than females.
  • The disease is commonly diagnosed in people between the ages of 50 and 70 years.
  • Mesothelioma is diagnosed in the stages, ranging from I to IV. The higher point numbers indicate a more advanced case.

About Mesothelioma Cancer

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?

MesotheliomaMesothelioma 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.

Pleural Mesothelioma

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.

Peritoneal Mesothelioma

Mesothelioma (1)

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.
