Mesothelioma: A Brief Overview

by Thomas Berten

Introduction
Mesothelioma is a cancer which affects the tissue which surrounds and protects various organs in the body. This tissue is called the Mesothelium, and Mesothelioma causes it to become abnormal, divide without control, and invade and damage nearby organs. The most common form is pleural mesothelioma which affects the sac that lines the chest cavity and protects the lungs (the pleura). Other forms are peritoneum mesothelioma (which affects the abdominal cavity) and pericardium mesothelioma (affecting the lining around the heart). The tumours can be either benign (non-cancerous) or malignant (cancerous) although they are most often malignant.

Causes
Mesothelioma is caused by the inhalation of asbestos, a fibrous carcinogenic. These fibres lodge themselves in the lining of the lung affecting the mesothelial cells. Sometimes they cause scarring of the lungs (which is called asbestosis) but this is not cancerous. They can, however, trigger tumour growth between 20 to 50 years after they are inhaled (the average is 35 to 40 years). Asbestos fibres which are swallowed can reach the lining of the abdominal cavity where they play a part in causing peritoneal mesothelioma.

It is generally the case that the longer or more intense the exposure to asbestos the more likely Mesothelioma is to occur. However, there are cases of people getting Mesothelioma years after having worked with it for just a few months. The families of asbestos workers are also at risk as they would possibly have been exposed to asbestos fibres on the clothing of their loved ones.

The dangers of asbestos are now well known, but this was not always the case. Before the 1970s asbestos was a primary insulating material with little or no control in its use or handling. The resulting increase in cases of Mesothelioma is a direct cause of these past practices.

Symptoms
Mesothelioma is often advanced before symptoms occur. This means that the prognosis is not usually very good, with the average survival time for all stages of Malignant Mesothelioma being about one year. Symptoms resemble pneumonia, which coughs, breathing difficulties and abdominal pain being common.

Treatments
Mesothelioma can be treated by chemotherapy, radiotherapy or surgery, or a combination of the three.

Surgery
Extra pleural pneumonectomy is where the entire lung and a portion of the lining of the chest, the diaphragm, and some or the entire sac which surrounds the heart is removed.

Wide local excision targets and removes the cancer and a limited amount of the healthy tissue surrounding the cancerous region.

Pleurectomy and decortication removes part of the covering of the lungs, as well as the lining of the chest and portions of the outside covering of the lungs.

Pleurodesis uses a blend of chemicals and/or drugs to create an intentional scar between the layers of the pleura. Post surgery, the space created by the scar must be drained, using either a catheter or chest tube, and is then filled with a chemical which inhibits the accumulation of fluid in the pleura cavity.

Radiation Therapy
Radiation Therapy uses high energy x-rays to kill cancer cells.

In External radiation therapy a machine emits radiation in a targeted stream at a certain portion of the body.

Internal radiation therapy uses needles, seeds and catheters to place radioactive substance directly on or near the cancer.

Chemotherapy
Chemotherapy uses cancer targeting drugs to stop the cells them from dividing and thus prevent their growth.

Mesothelioma - What are the treatments?

by Mesothelioma-Resource-Network Staff Writer

The location, stage of the disease along with the paitent's age and general health all play a role in determining the treatment of mesothelioma. Options for treatement generally include surgery, radiation therapy and chemo therapy.

Surgery is a common treatment for mesothelioma. The doctor may remove part of the lining of the chest or abdomen and some of the tissue around it. For cancer of the pleura (pleural mesothelioma), a lung may be removed in an operation called a pneumonectomy. Sometimes part of the diaphragm, the muscle below the lungs that helps with breathing, is also removed.

Radiation therapy, also called radiotherapy, involves the use of high-energy rays to kill cancer cells and shrink tumors. Radiation therapy affects the cancer cells only in the treated area. The radiation may come from a machine (external radiation) or from putting materials that produce radiation through thin plastic tubes into the area where the cancer cells are found.

Chemotherapy is the use of anticancer drugs to kill cancer cells throughout the body. Most drugs used to treat mesothelioma are given by injection into a vein (intravenous or IV). Doctors are also studying the effectiveness of putting chemotherapy directly into the chest or abdomen (intracavitary chemotherapy).

To relieve symptoms and control pain, the doctor may use a needle or a thin tube to drain fluid that has built up in the chest or abdomen. The procedure for removing fluid from the chest is called thoracentesis. Removal of fluid from the abdomen is called paracentesis. Drugs may be given through a tube in the chest to prevent more fluid from accumulating. Radiation therapy and surgery may also be helpful in relieving symptoms.

Mesothelioma - History, Hazards and Dietary Advice

by Baymaster

History of asbestos.
There are four main types of asbestos; Amosite (brown fibers), Anthophyllite (gray fibers), white Christie, and blue Crocidolite. Chrysotile has curly fibers while the other three have rod like fibers. These fibers fragment into dust quite readily and waft into the air. They can adhere to skin or clothing and are easily swallowed or inhaled.

Half a century ago, asbestos was hailed by many as a miracle product. They said nearly anything could be made from this mineral. It as used as an additive to reinforce mortar and plastics. Asbestos fibers can also be separated into fine threads that do not conduct electricity and are unaffected by heat or chemicals.

Use of asbestos drastically increased during World War II. Shipbuilding incorporated asbestos extensively in freighters and support vessels to insulate boilers, steam pipes and hot water pipes. Asbestos became the miracle construction material as it was readily obtained, processed, and transported. After WWII cars used asbestos in brake shoes and clutch pads. Asbestos found its way into residential and industrial building materials, water supply, sewage materials, ceiling and floor tiles, and vermiculite garden materials to name a few products.

In the 1970's, following the discoveries of the health dangers of asbestos dust inhalation, the U.S Consumer Product Safety Commission prohibited the use of asbestos in several products that could liberate asbestos fibers into the environment during use. Regulations governing the use of asbestos and public concern since 1970 have created a significant drop in the use of asbestos in the United States. The same pattern has been seen in most of the developed world.

In 1989 all new uses of asbestos were banned by the Environmental Protection Agency while any old uses before that year were still allowed. The EPA suggested that schools inspect for damaged asbestos and eliminate any exposure or enclose it in protective barriers. Vermiculite, widely used in horticulture, became a concern of the EPA . They recommended outdoor use, limiting the amount of dust used, and keeping vermiculite damp.

Health hazards
Asbestos may create serious health hazards such as coughing, lung damage, shortness of breath, and lung cancer. Most people do not become sick in the early stages of contact but usually need continued exposure. This often means on jobs such as mining, milling, manufacturing asbestos products, and the building construction industry. Firemen, demolition and destruction workers, drywall removers, and anyone else involved in trades that involve destruction of buildings, ships, and automobiles are also exposed to the hazards of asbestos.

Over a number of years continual exposure to asbestos can cause very serious health problems, such as mesothelioma. Mesothelioma is a rare type of carcinoma of the membrane that lines numerous cavities of the body, including the lungs, abdomen and heart, and has been associated with exposure to asbestos dust. In mesothelioma, the cells of the mesothelioma metastasize and damage adjacent organs and tissues.

Mesothelioma may not develop for a long period of time, often as long as twenty-five or thirty-five years before full blown symptoms appear. Not all workers who have been exposed will develop diseases, but workers who have been exposed to it may bring fibers on their clothing, hair, shoes, and skin home to their families. To circumvent this risk, most industries require workers to bathe and change their clothing before they leave work.

Dietary advice for Mesothelioma patients
Doctors and nutritionists may recommend a special cancer diet because many mesothelioma patients tend to lose their appetites due to worry over their condition. Also, those who are undergoing treatment may choose not to eat because of the unpleasant side effects they may experience. Chemotherapy and some medications may cause an imbalance of nutrients that must be corrected in order to keep the body as strong as possible and to keep the patient from losing an excessive amount of weight. Other side effects of mesothelioma treatment can include nausea, vomiting, constipation,dry mouth and a change in the sense of smell or taste.

In our childhood we were all told to eat our vegetables. Forcing down cabbage and sprouts was supposed to make us bigger and stronger. Well, so it is for mesothelioma patients. Diet is often an overlooked subject for cancer patients, but eating the right nutritional foods for strength and energy is just as important as taking the proper medication.

Mesothelioma patients undergoing treatment must follow a special cancer diet devised by their nutritionists. The details of every patient's mesothelioma diet will vary. Some patients will need to incorporate more fat into their diets, while others may need more protein. Cancer diets involve eating the correct amounts of protein and calories as well as drinking the right amount of water to keep the ailing body replenished and energized. The body needs plenty of nourishment when it is going through chemotherapy or even when the patient is taking certain medications.

It is important that patients devise a cancer diet under the guidance of their doctor and nutritionist to ensure that they obtain the proper amount of nutrients to improve their quality of life.

Protein is important for any cancer patient because it helps repair tissue damaged by surgery, chemotherapy, or radiation. Protein also helps maintain a strong and healthy immune system, lowering a mesothelioma patient's risk of infection after aggressive cancer treatments. The National Cancer Institute recommends increasing protein in a cancer diet with cheese, milk, ice cream, yoghurt, eggs, nuts, peanut butter, meats and fish.

Fats are an essential part of the cancer diet because they supply the body with the necessary energy it needs while undergoing treatment. The amount of fats a cancer diet should consist of is dependent on a mesothelioma patient's age and body size. The National Cancer Institute recommends increasing caloric intake with such foods as butter, milk, cheese, honey, sugar, granola and dried fruits.

Water is another essential component of the cancer diet. Without a significant amount of water, the body will dehydrate. It is important that anyone undergoing cancer treatment drink sufficient water to keep their bodies hydrated and replenished.

Mesothelioma: 5 Top Tips to Help Cope Easier

by George Spence

Living with a diagnosis of Mesothelioma can be very emotionally difficult to deal with. Understandably, you may be feeling upset and confused as it is not uncommon for Mesothelioma to be diagnosed at an advanced stage. Here are five tips to help you or anyone else cope with Mesothelioma:

1: Coping with your feelings.
Everyone has a different reaction when they learn that they have Mesothelioma. A wide range of feelings and emotions such as confusion, upset , worried, depression, shock, fear, denial, anger, negativity, etc. And it is not uncommon for people to feel relieved on learning they have Mesothelioma as they feel it is better to know than not know at all.

Just because you are having different feelings to others (or to the ones listed above) does not mean that you are not coping. There is no text book way to cope with Mesothelioma. The feelings you experience are naturally right for you so do not compare your feelings with anyone else.

2: Finding others to talk to.
Your family and friends may find it hard to talk with each other about Mesothelioma. This is not unusual as they may be scared of frightening you or make it more difficult to talk about in the future. Most Mesothelioma patients feel that a problem shared is a problem halved. In some cases, patients feel it is best just to be listened to and know that someone is there if a ‘good pair of listening ears’ is needed. Get the subject out in the open.

3: How to tell children.
It is never easy to tell children about Mesothelioma, even more difficult if they are small. Most patients will have small children, young relatives or the children of friends in their lives.

If the child you need to speak with is very small, start off by explaining that the person in question is very poorly. If the child is a little older, it is a good idea to explain Mesothelioma cancer as good cells and bad cells in the body. It is also a good idea if you know a little about Mesothelioma or cancer but overall, try to keep it simple.

You will also need to listen to the questions of the child and answer them the best you can without trying to upset them too much. Starting off with small bits of information and building up to the bigger picture as time goes on is a good way to go.

But don’t keep any secrets. Children are good at telling when something is not right and it may be harder for them to cope with uncertainty that it would be coping with the truth.

As adults, it can be natural to try and protect children from the truth but children can pick up on unusual comings and goings and will feel left out. Keep them informed, even if it is with just little snippets of information..

If possible, try to have a word with the childs school teacher to let them know that someone close to them is ill. Hopefully, the teacher will keep an eye on the child in case of any changes in the childs behaviour.

4. What can you do?
A feeling of helplessness is not unusual when someone is first told that they have Mesothelioma. Try and learn to understand Mesothelioma as this will help you and your family to take action and know what to expect. It is best to talk to a professional such as your doctor if you need more information as they will be able to advise you on your specific case which is always better than getting general information about Mesothelioma from a book or the internet. Be sure to take a list of questions to save time for you and your doctor.

It may be a good idea to see if there are any local support groups you can join. Finding people going through a similar experience as yourself can help you cope. Your doctor or hospital will be able to let you know if there are any support groups near to you.

As you are having treatment, you will find that you may not be able to do as much as you would like on a day to day basis. Once you start to feel a little better, try and do some simple tasks and do a little more each day. This will help with confidence but always remember not to over do things.

A lot of patients try to fight Mesothelioma by planning a healthy diet, learning relaxation techniques and taking regular exercise. You don’t have to do this, only if you would like to try it. The last thing you need are more dramatic changes in your life if you’re not ready for them. But if you do decide to give exercise a go, start slowly and set realistic targets. You will have good days and bad days so always plan your activity on how you feel on the day.

5: Who else can help?
More support can come from your GP if needed and hospitals can give advice and support through cancer nurses and specially trained staff will advise you on any worries you may have.

For financial help, check any insurance policies you have to see if you are covered. It is also advisable to seek financial help from your local welfare office if needed.

Sometimes it is nice to talk with someone who has nothing to do with Mesothelioma. You may want to try counselling or if you’re religious, speaking with a local minister or anyone else involved in your faith.
