A common question for those who have been diagnosed with mesothelioma is “How long I can live with this disease?” In fact, many patients turn to their doctor with this question as well as their friends and family members. As with most diseases, however, there is no response in terms of life expectancy of a patient meso, but – in general – the survival rate of mesothelioma is based on a number of different factors. Each case is a bit different and although the survival rate for victims of mesothelioma has traditionally been grim, more and more patients are living longer with the disease, scientists discover more and better ways to detect and treat disease.
The survival rates of patients with mesothelioma depends on many factors which may include any or all of the following:
- latency period of mesothelioma – Mesothelioma is a rare form of cancer which has a long latency period. Essentially, this means that the disease often “hides” in the body for many years, sometimes four or five decades. Therefore, 40-50 years may have passed since the first exposure to asbestos for the first time. This long latency period also means that the disease is not detected until symptoms appear. Often, at that time, cancer has spread from the main area to other parts of the body.
- stage of disease at diagnosis – Those whose mesothelioma is discovered in Stage 1 and 2 have a much better chance of surviving the disease for a prolonged period of time because there are more treatment options available to them. Those with stage 3 or 4 mesothelioma have fewer treatment options. The poor prognosis of mesothelioma is observed in these patients with advanced cancer are symptomatic or with distant metastasis of primary tumor, ie, the cancer has spread from the main area to other parts of the body.
- operability of the tumor – Due to the latency period mentioned above, surgery to remove the primary tumor mesothelioma is often not an option. However, if the disease is discovered at an early stage, a surgical procedure to remove the tumor may be a possibility, especially when the patient is healthy.
- patient’s age – The younger the patient, the greater the chance of survival. Studies have shown that age is indeed a factor in improved survival rate and young patients certainly fair.
- Comorbidity with other diseases – Patients, especially older ones, who have many medical problems are less likely to survive for a long time with mesothelioma. This is especially true in older patients, who represent a large number of victims of mesothelioma. Heart disease, kidney problems, hypertension, diabetes, and a host of other diseases or disorders can seriously affect the treatment options and, therefore, shortens the life expectancy of the patient.
- Mesothelioma treatment plan – The length of time a victim survives mesothelioma may depend on treatment (s) you receive. Most doctors will be as aggressive as possible, understanding that this is a difficult cancer to treat.
- area and type of disease – Mesothelioma occurs in various forms. About 75 percent of cases occur in the pleura, 15 to 20 percent in the peritoneum, and only 5 percent in the pericardium. The pleural mesothelioma is easier to treat and patients usually have a higher survival rate of mesothelioma than those whose disease is focused elsewhere. In addition, people with epithelial mesothelioma (most cases are this type) have a better prognosis than those with other types of mesothelioma.
Mesothelioma is a rare form of cancer, bone tumor involving the mesothelial cells of the protective outer membranes of some internal organs as such, lungs, heart and abdominal organs, diaphragm pleura best known is and its function is to be a lubricating surface that protects the lungs from rubbing against the rib cage.
Currently, all cases of mesothelioma (cancer of the pleura), and lung cancer are related to the inhalation of asbestos fibers. When inhaled, these fibers can cause scarring in the tissues of the lung, which can not expand and contract normally.
A year are diagnosed in about 15,000 cases in the world, how to treat this cancer is by chemotherapy, radiotherapy and alternative medicines eligible for convatir disease. Usually those affected by this disease are over fifty years. The characteristics of asbestos-name of a group of different types of minerals are, long fibers, resistant, can be separated, are flexible, can be intertwined, also resist high temperatures.
Asbestos fibers do not dissolve in water or evaporate into the air, so these pieces of fibers can enter the water and air by the erosion of natural deposits and wear manufactured asbestos products, asbestos minerals always are widely distributed in the environment. Can be found in large natural deposits, or even contaminants in other minerals, eg, vermiculite, talc and chrysotile deposits which are in the tremolite asbestos. The most likely way of exposure to asbestos is through inhalation of asbestos fibers airborne, these fibers can come from natural sources or wear asbestos or disturbance of manufactured products, eg automotive brake and clutch linings, tiles and tiles, dry wall, insulation, cement and roof tiles, however, these products do not always contain asbestos.
In general, almost all air sample can be detected low levels of asbestos, which are little or no risk to our health. The levels found near an asbestos factory or mine can reach 11,000 fibres/m3 (0.01 fibers / ml) or more. In general, levels may be higher than average near buildings containing asbestos products are being demolished or renovated or near a waste site where asbestos is not covered and stored properly in order to protect from wind erosion.
As Asbestos Causes Cancer
The exact method by which asbestos causes cancer in mesothelial cells is currently unknown. However, there are four different theories:
1. Asbestos causes irritation of mesothelial cells, causing cell damage and eventually causing cancer
2. Asbestos fibers enter the mesothelial cells and damage molecules that are crucial for normal cell division
3. Asbestos fibers promote the formation of free radicals, which damage DNA and cause mesothelial cells turn into cancer cells
4. Asbestos fibers cause mesothelial cells produce molecules called oncoproteins that make cancer cells become
As with other malignant cancers, the key element is that the cells begin to divide continuously. Eventually these cells form tumors that inhibit the normal functioning of other cells and organs.
Symptoms
The first symptoms of malignant mesothelioma are not specific and can often resemble viral infections – this means that early diagnosis of this type of cancer is difficult. Symptoms such as shortness of breath, chest pain or a persistent cough are common. Night sweating, fever and weight loss are less common symptoms in people with pleural mesothelioma. Symptoms of peritoneal mesothelioma include pain or swelling in the abdominal area, nausea, weight loss, bowel obstructions, and anemia.
Diagnosis
Malignant mesothelioma diagnosis quickly and accurately is very important for two reasons. First, the correct diagnosis is essential to treat patients as soon as possible. The second reason is that some patients might want to try and obtain financial compensation from the company that was responsible for his exposure to asbestos.
The diagnosis is based on the patient’s symptoms, along with a physical examination. This I can include chest x-rays and other procedures designed to discover what kind of cancer is and what stage you are. The diagnosis is confirmed by biopsy or blood tests that determine whether cancer cells are present or not in the body.
Forecast
In general, the prognosis (life expectancy) for people with malignant mesothelioma is very poor. The first symptoms of the disease are so general that this type of cancer is very difficult to diagnose in the early stages, and when confirming an accurate diagnosis, about 50% of patients will die within a year.
Treatment
The most common treatments for malignant mesothelioma are surgery and chemotherapy, usually used in conjunction with each other. Surgical procedures typically involve the extraction of malignant cells to improve the quality of life for patients and continuing with chemotherapy to remove residual cancer cells.
Other forms of treatment are largely experimental. These types of treatment include immunotherapy and gene therapy. Immunotherapy involves manipulating the body’s own immune system in an effort to induce it to kill cancer cells. Gene therapy involves using a virus that has been genetically modified to infect cancer cells and make them produce molecules that are only capable of killing malignant mesothelioma cells.
Mesothelioma cancer is a rare form of the disease in which cancer cells develop in the pleura, peritoneum, or pericardium – the lining of the chest, abdomen and the area around the heart. This form of cancer is almost always caused by previous exposure to asbestos.
Peritoneal mesothelioma
Cancer is one-fifth to one third of cases are diagnosed. The symptoms of this type of mesothelioma include weight loss, swelling and pain in the abdomen due to fluid accumulation. Victims of other types of mesothelioma can develop pain in the chest wall, the fluid around the lungs, anemia, shortness of breath, or symptoms of anemia, cough, or the tendency to wheeze and cough up blood. In severe cases, can form tumors in the lungs or abdominal cavity, causing the collapse of the lungs.
While only a short period of exposure to asbestos, as little as one or two months, is required for this type of cancer that occurs, you can take a long time before symptoms appear. People who were exposed in the decade of 1940 are only now being diagnosed as mesothelioma cancer has a long latency period. If you are diagnosed with mesothelioma, the prognosis may vary according to how early it was detected. Research in alternative medicine and conventional therapies for the treatment of this disease continues. Conventional drugs used to fight cancer mesothelioma include Alimta and other chemotherapy drugs, surgery to remove tumors, and radiotherapy.
In addition to these treatments, a series of alternative medicine therapies may be able to reduce the symptoms of mesothelioma. Is called complementary and alternative medicine, or CAM, this group of doctors and health care options and practices are not considered part of general medical practice. However, that does not mean they are ineffective. Some health professionals practice both CAM and conventional medicine, and combine the two with good results. This is known as integrative medicine.
What is mesothelioma?
Malignant Mesothelioma is a rare form of cancer that originates in the mesothelium, the membrane that covers and protects most internal organs of the body. The mesothelium has two layers, one surrounding the organ itself, and the other forming a lining bag inside it. Between these two layers are usually produces a small amount of liquid to lubricate the movement of organs protected. When the normal cells of the mesothelium out of control and multiply rapidly, it is called mesothelioma. The most common form of mesothelioma is mesothelioma pleural, which is generated in the lining of the lungs. Other forms are mesothelioma peritoneal, affecting the lining of the abdominal cavity, and mesothelioma pericardial, affecting the lining of the heart.
What causes mesothelioma?
Mesothelioma is almost always prevent exposure to asbestos fiber. Many people have been exposed in the military, others because of their work, others, secondarily, through contact with workers exposed. Because of its latency, the cancer may not occur for 20-50 years and higher after exposure.
What types of products generally contain asbestos?
These products generally contain asbestos in varying concentrations. This list is not exhaustive and is intended only as a general reference.
* Coatings shaped or molded, used for thermal insulation of pipes and boilers
* Asbestos spray used as fire protection in ducts, in firebreaks, panels, partitions in, in the floor boards, ceiling panels and around structural steel
* Insulating boards used for fire protection, thermal insulation, the partitions and pipes
* Coatings used asbestos in firebreaks and ceiling cavities
* Double-pressed cardboard, paper and paper products used for the insulation of electrical equipment, asbestos paper may also be used as a flame retardant coating on the panels of wood fiber
* All asbestos cement products, both flat corrugated sheets used for roofing or wall covering, cement products were also used in the gutters in the rain and water tanks
* Textured finish (such as Artex)
* Roofing material made of bitumen
* Tile Vinyl or thermoplastic
The pleura in a double layer covering the lung
The pleura is a membrane consisting of two thin sheets (visceral and parietal). They are the lungs and the inside of the chest cavity. In case of illness the space between the two pleural (pleural cavity) may fill with fluid, which causes breathing difficulties.
Asbestos case
It is assumed that about half of all malignant mesothelioma is caused by asbestos dust. Mesothelioma can develop decades after exposure to asbestos. If the asbestos dust may cause cancer should notify the appropriate accident insurance of the employer with whom the patient was exposed to dust, even if the patient is retired.
The lungs ‘walled’
The pleural mesothelioma is spread across the pleura and may invade nearby organs like the lungs or diaphragm. Arise breathing problems, coughing and chest pain. For the diagnosis is used in radiography, computed tomography or other methods of examination of the chest. It also collects fluid from the pleural cavity.
Surgery, radio and chemotherapy
The type of treatment depends on the spread of cancer. Typically, therapy is a combination of surgery, radio and chemotherapy. If pleural mesothelioma is diagnosed in a very advanced stage of recovery is not possible.
Pleural metastases
Much more frequent pleural mesothelioma are pleural metastasis, ie secondary tumors. Pleural metastases arise mostly from malignant tumors of lung, breast, stomach and esophagus.
Other risk factors
* Exposure to asbestos, a fibrous mineral used as insulation in homes and buildings, also increases the risk of lung cancer. In houses, this material is not dangerous as they are not broken or handled in the open air, which may be the case during the renovations.
* Wood stoves, if they are not waterproof, are sources of fine particles in the air of homes, particularly dust and ashes. Wood smoke contains over 7,000 toxic substances. NB In its natural form, talc may contain asbestos. However, Canadian law requires, since 1973, as consumer products containing talc (body powders, face and baby) are free of asbestos.
* Being frequently exposed to air pollution. The air pollution is responsible for 5% of all deaths from cancer of the trachea, bronchus and lungs. The particles from burning coal, oil, natural gas and the incineration of garbage are damage. The problem is especially crucial in countries poorer and densely populated, particularly in Asia, but relates to some degree, all major cities.
* Having a diet low in fruits and vegetables. Twenty studies (cohort or case-control) on eating habits show a slightly reduced risk among consumers of fruits and vegetables rich in beta-carotene (sweet potatoes, pumpkins, carrots, spinach and other green vegetables dark, winter squash, etc..). In general, consumption of fruit and vegetables exert a protective effect in people exposed to smoke tobacco.
Epidemiological studies indicate that consumed in supplement form (at a dose of 20 mg or more per day), beta-carotene slightly increases the risk of lung cancer and mortality among smokers. It is not known if this negative effect persists when the beta-carotene is used in combination with other carotenoids in supplements.
Potential risk factors
* Smoking marijuana. For now, the data tend to show that marijuana does not increase the risk of lung cancer. Smoke marijuana, or cannabis, although exempting nicotine, contains several carcinogens found in tobacco smoke. Researchers believe that tetrahydrocannabinol (THC) present in cannabis smoke’s effect. Marijuana smoke is often inhaled deeply and held longer in the lungs. Some data suggest that marijuana may cause oral cancer.
* Smoking the hookah (pipe eastern water pipe, hookah). The data are currently insufficient to determine the impact of this practice on the risk of lung cancer. The amount of tobacco smoke hookah is much lower than that found in cigarettes.Smoking the hookah is a tradition in North Africa and the Middle East. The smoker draws through a long pipe, smoke flavored tobacco. Although filtered water, smoke contain certain amounts of nicotine, carbon monoxide and other harmful substances.
Avoid these factors reduces the risk of lung cancer. However, most people who have a risk factor will not be affected by this cancer. In addition, sometimes the disease occurs even in the absence of all these risk factors.
Major risk factor
* Smoking cigarettes. By far, this is the most important risk factor. Smokers are 10-25 times more likely to have lung cancer than non-smokers. The risk depends on the age at which smoking began, number of years and the amount of cigarettes smoked per day. Although lung cancer takes several years to occur, physiological changes in lung tissue are visible long before.
On other types of cigarettes. Cigarettes “exotic” (kreteks, bidis, etc..), Often flavored, are not safer than cigarettes, according to the American Cancer Society. Some have no filter, others contain less tobacco, but more nicotine than regular cigarettes. Note that chewing tobacco is one of the main causes of oral cancer.
Light cigarettes: Safer? According to experts at the Mayo Clinic in the United States, believing that it reduces their risk of cancer by choosing cigarettes low in tar or nicotine is often error. The slight protective effect is counteracted by the fact that most people who smoke these cigarettes more deeply inhale the smoke without realizing it, to get the same amount of nicotine.
Other risk factors
* Smoking a pipe or cigar. Their smoke is also harmful to lungs than cigarettes. However, pipe smokers and cigar smokers generally less frequently than cigarette smokers, making them less risky.
* Being frequently exposed to secondhand smoke. Among non-smokers, there is the main risk factor for lung cancer. The proof has been established by studying the spouses of smokers. Studies show that their risk increases by 20% to 30%, compared to spouses of non-smokers.
* Being exposed to carcinogens in the context of a job. Carcinogens may cause genetic mutations that cause cancer. This is the case of exposed workers to asbestos (minors in an asbestos mine, construction workers), radon (in uranium mining), chromium (welders) or vapor ovens gas. Among these workers, the risk of lung cancer is even higher if they smoke cigarettes. Those in frequent contact with chemicals or minerals that could be inhaled (arsenic, beryllium, vinyl chloride, nickel chromates, coal products, mustard gas, gasoline, diesel exhausts, dust talcum, etc..) and who do not respect security measures have also increased risk.
* Being exposed to carcinogens at home. Exposure to high concentrations of radon in the home increases the risk of lung cancer, especially among smokers. Radon is a radioactive gas that occurs naturally in soil and rocks, resulting from the degradation of uranium. It is colorless, odorless and invisible. The risk occurs in houses built on soil containing high concentrations of uranium. Radon seep through the basement through dirt floors, concrete walls (and even more if they are cracked), drains and sump pumps.
Unless your home was built after 1999, there is a possibility that asbestos or asbestos materials were used somewhere in a structure as a whole or renovation. The categorical duration of asbestos were used usually made within the home structure, a 1950 to a mid-1980s.
The appeal for homeowners is that asbestos is most formidable to identify, usually when it has been combined to cement, resins or alternative materials. Asbestos lagging and insulation play skills have been embellished or solitary alternative materials so we will not be funds to discuss the rule by seeking them. In many cases, one usually approach definitely noticed asbestos is through laboratory analysis.
In many cases, one usually approach definitely noticed asbestos is through laboratory analysis.
Here a lot of common places where we can find expertise asbestos in a home:
Entrance gym – running on a backup copy of a composite box
Kitchen – insulating the house around executive heating boiler, aged vinyl or thermoplastic construction tiles
Living Room – Artex and identically textured coating on the ceiling tiles or walls, wall panels, usually around windows, electric storage heaters
Bathroom – Toilet well, bath panels, air sideboard feed
Loft – siren lagging, asbestos concrete H2O tank; form insulation
Outside – outer cladding, soffit boards, gutters and down pipes, roof tiles tiles
Garden – garages, sheds and outbuildings
Wherever we find asbestos, take care not to anxiety or repair it. If we have been uncertain about an item competence enclose asbestos, have it checked by an expert.
If we must have a private asbestos from your home get an online asbestos dismissal allude to from a web site that usually deals conscientiously protected from dismissal asbestos contractors to be certain a prosecution is completed safely.
Mesothelioma?
Abdominal mesothelioma is an intensely singular form of mesothelioma cancer. Usually described as peritoneal mesothelioma, a cancer affecting an intestinal lining, it is also well well well known as a peritoneum. In a bowel, is a serious membrane, which is also well well well known as a parietal peritoneum, and this surface continues until an intestinal peritoneum which lines an organ. With intestinal mesothelioma, an intestinal and parietal peritoneum lining has been influenced by an increase of carcenogenic cells.
Most often, cancer occurs when an intestinal specific initial developer pleural mesothelioma is that when a backing of a lung develops carcenogenic cells after transformation of asbestos. Pleural mesothelioma can then spread to the peritoneal form as well as funds peritoneal mesothelioma, which accounts for reduction than a third of all mesothelioma diagnoses.
How is peritoneal mesothelioma Contracted?
Abdominal or peritoneal, mesothelioma is caused by a transformation of asbestos fibers or asbestos dust. Asbestos is an element that is trailing from vermiculite, a vegetable that was heavily mined in the United States as well as about a universe in a 20 century. Asbestos was most commonly used as an insulation on the inside of a building a lot of attention since it was fire resistant, as well as were grown in cheap prices.
