INTRODUCTION
Mesothelioma
Mesothelioma is a type of cancer that affects the mesothelium, a vital layer of cells that line the body’s internal organs, providing a protective barrier and facilitating physiological functions. This blog will focus on the various aspects of understanding mesothelioma. Despite being a rare form of cancer, this disease has gained notoriety due to its association with exposure to asbestos, a naturally occurring mineral that was widely utilized in various industries due to its exceptional strength, heat resistance, and durability.
Incidence of mesothelioma
According to the world health organization (WHO), 43000 deaths with this type of cancer occur worldwide in every ear. However, it is fairly rare in the USA accounting for only 3000 new cases every year.
What is the main cause of mesothelioma?
It is imperative to underscore that the majority of cases still stem from asbestos exposure, and the other causes are relatively uncommon. If you harbor concerns regarding your risk, it is advisable to consult with a medical professional for a comprehensive evaluation and guidance.
What is asbestos?
Asbestos consists of six different minerals made up of fibers and are found naturally in the environment. One of the qualities of Asbestos minerals is that they don’t dissolve in water or evaporate. They are also resistant to heat and fire and cannot be broken down easily by chemicals.
The Link between Asbestos Exposure and Mesothelioma
Asbestos was widely employed in the construction and industrial sectors until the perils of asbestos exposure became widely recognized. Inhalation of asbestos fibers can lead to their accumulation in the mesothelium, inducing irritation and inflammation that can progress to mesothelioma. The latency period between asbestos exposure and the onset of cancer can range from 20 to 50 years, making early diagnosis challenging.
Where asbestos is commercially used?
As this fiber is very strong and heat resistant, it is used in various materials. Some examples are;
- Building materials like roofing shingles, tiles, asbestos types of cement
- Friction products like automobile brakes, clutches, and auto transmission parts.
- Heat resistant fabrics
- Coating
- Gaskets
- Some packages material
- steam and hot water pipes
- furnaces and boilers
Which professionals are affected by mesothelioma?
In those professions or industries where asbestos is widely used, there are chances of contracting this tumor. These professions may include;
- Construction workers
- Industrial workers
- Power plants workers
- firefighters
These employees frequently handle asbestos-containing materials in greater volumes.
What are the other causes of Mesothelioma?
The primordial cause of mesothelioma is widely recognized to be asbestos exposure, but there exist other, less frequent sources that can trigger the emergence of this malignancy. A few such causes are outlined below:
1- Hereditary Heterogeneity:
In a minority of cases, this may stem from a genetic anomaly that is transferred intergenerationally.
2- Ionizing Irradiance:
Prolonged exposure to elevated doses of radiation, such as those experienced by certain patients undergoing radiation therapy for neoplastic conditions, may heighten the probability of onset.
3- Simian Virus 40 (SV40):
SV40 is a virus discovered in some mesothelioma tumors, and it is hypothesized that contact with polio vaccines contaminated with SV40 may elevate the risk.
4- Zeolite exposure:
Research has indicated that exposure to zeolites, naturally occurring minerals, may augment the likelihood of developing this disease.
Types of Mesothelioma
Pleural mesothelioma (mesothelioma lung cancer):
Pleural mesothelioma is a type of cancer that affects the pleura, which is the thin layer of tissue that lines the chest cavity and surrounds the lungs. It is caused by exposure to asbestos, a naturally occurring mineral that was widely used in various applications until its health risks became better understood in the latter half of the 20th century.
When asbestos fibers are inhaled, they can become lodged in the pleura and cause irritation and inflammation over time. This can eventually lead to the development of pleural mesothelioma, slow-growing cancer that can take 20-50 years or more to develop after initial asbestos exposure.
Heart or pericardial mesothelioma
Pericardial mesothelioma affects the pericardium – the sac-like sheath enveloping the heart. This disease, frequently traced to asbestos exposure, manifests as a neoplastic growth in the protective tissue layer that surrounds the heart, thereby inducing an assortment of symptoms and physiological complexities.
In the presence of symptoms suggestive of pericardial mesothelioma, it is imperative to seek the advice of a seasoned medical practitioner, as prompt and early intervention can result in improved outcomes and an augmented quality of life.
Peritoneal or abdominal mesothelioma
Peritoneal mesothelioma has deleterious effects on the peritoneum – a thin, complexly structured membrane enveloping the abdominal cavity. Symptoms, including but not limited to abdominal pain, bloating, distension, weight loss, and cachexia
Testicular mesothelioma
Testicular mesothelioma is a rare condition that affects the membrane of the testis called tunica vaginalis. It may cause swelling, pain, and a mass in the scrotum.
Symptoms of mesothelioma
Mesothelioma, a malignancy that affects the delicate membranes enveloping internal organs, may manifest through various telltale symptoms that can raise alarm. The following may be some signs and symptoms
Lungs/Respiratory symptoms:
Shortness of breath, coughing, and wheezing may signify the presence of pleural mesothelioma, impacting the lung lining. Symptoms of pleural mesothelioma may include chest pain, shortness of breath, coughing, and weight loss. The disease can also cause fluid to accumulate in the chest, a condition known as pleural effusion, which can cause additional symptoms such as difficulty breathing and chest pain.
Digestive or Abdominal symptoms:
An accumulation of fluid in the abdominal cavity may result in constipation or diarrhea, swelling, and bloating.
Weight loss:
Unexpected and rapid weight loss, along with a pervasive sense of weakness and fatigue, may be symptomatic of mesothelioma.
Fatigue:
Fatigue and a general sense of weakness may also be experienced by individuals with mesothelioma, potentially due to the physical toll that the disease can take on the body.
Night Sweats and high temperature:
some individuals with mesothelioma may experience night sweats, insomnia, and fever, which can be indicative of an underlying infection or inflammation
Pain:
Persistent discomfort in the chest or abdominal realm, compounded by physical activity or movement, may be indicative of this tumor.
DIAGNOSIS OF MESOTHELIOMA
Diagnosing Mesothelioma: Identifying Symptoms and Utilizing Diagnostic Tools
The symptoms are often non-specific and can take several decades to develop after asbestos exposure. Various methods like X-ray, CT scan and laparoscopic examination are used. A biopsy of the affected tissue is the most common diagnostic tool, with the sample examined under a microscope for evidence of cancer cells.
Stages of Mesothelioma
The progression is typically divided into four distinctive stages, which are determined by the extent of the malignancy’s dissemination. These stages are:
1. Stage 1: In this phase, the cancer is restricted to a single region, predominantly the pleural or peritoneal lining.
2. Stage 2: At this stage, cancer has expanded to neighboring tissues but has yet to infiltrate the lymphatic system.
3. Stage 3: In this phase, cancer has reached remote lymph nodes or other organs.
4. Stage 4: This stage is characterized by the widespread dissemination of cancer to multiple areas of the body, thereby marking the advanced or metastatic stage.
It’s vital to comprehend that these stages are general classifications and may not precisely depict the evolution of the disease for every patient. The stage is determined through a composite of diagnostic assessments, such as imaging scans and biopsy techniques.
Delineating the stage of mesothelioma is crucial for the selection of the most appropriate therapeutic approach and for determining the prognosis.
TREATMENT OF MESOTHELIOMA
Treatment Options for Mesothelioma:
Unfortunately, there is no cure for mesothelioma, but various treatments are available to manage its symptoms and improve outcomes for patients. Options include surgery, radiation therapy, chemotherapy, and a combination of these methods. The choice of treatment will depend on various factors, including the stage and location of the disease, the patient’s overall health, and their personal preferences.
Palliative care (Managing Symptoms and Improving Outcomes). This is the controlling of symptoms and making the life of the affected person easier.
Effectiveness of treatment
The effectiveness of treatment of each option available depends on the stages and types of mesothelioma. The experts have to decide what option they should go for treatment. Early diagnosis and treatment have better outcomes.
