Hello
Friend
Today I want to share you Misothelioma
different types that exist and their characteristics, so you have confidence in
what I'm going to share today, I have taken this information of The
Mesothelioma Cancer Center, which is based in the United States.
But wait, before I see a short and powerful
video that will help you understand much more today's topic.
TYPES OF MESOTHELIOMA
Mesothelioma is caused by long-term, repeated
exposure to asbestos fibers. The disease is generally found in four different
forms – pleural, peritoneal, pericardial, and testicular. In each case, the
cancer develops in mesothelial cells, which form the membranous linings that
surround and protect organs. The different names for each type of mesothelioma
refer to the point of origin of the cancer.
Mesothelial membranes are made up of two
different layers — the parietal layer and the visceral layer. Parietal layers
are outer layers, and these typically cover large areas such as the chest
cavity (in the case of pleural and pericardial membranes) and the abdominal
cavity (as in the case of peritoneal membranes). Visceral layers are those that
cover organs such as the lungs and heart. Mesothelioma develops in these
membranes when asbestos fibers become trapped in the spaces between mesothelial
cells.
Mesothelioma is a particularly aggressive type
of cancer and is highly resistant to treatment, resulting in very high
mortality rates and poor prognosis for people diagnosed with the disease. In
general, pleural mesothelioma responds more positively to treatment,
particularly if the disease is diagnosed early. However, all forms of
mesothelioma are difficult to diagnose, and unfortunately, it is common for the
disease to be diagnosed too late for treatment to be effective.
“The disease is

different forms –
pleural,

pericardial,
and testicular.”
Pleural
Mesothelioma
Pleural mesothelioma develops in the
mesothelial lining of the lungs, which is known as the pleura. About 70% of all
mesothelioma cases are pleural.
Symptoms of pleural mesothelioma include
difficulty swallowing, a persistent dry cough, persistent chest pain or pain
when breathing, and difficulty breathing even when resting. These symptoms
result from pressure on the lungs and respiratory system, caused by thickening
of the pleural membrane and fluid build-up between membrane layers. As the
cancer advances, lumps may develop under the skin of the chest.
Diagnosis of pleural mesothelioma involves
imaging tests such as chest X-rays, MRIs, and CT scans, and may also include
biopsies that remove tissue and fluid to test for the presence of cancer cells.
These tests also help determine the stage of the cancer and the options
available for treatment. Generally, patients in Stage I and II mesothelioma are
good candidates for surgery, whereas patients in Stages III and IV have more
limited treatment options, and may only be able to receive palliative
treatments.
Peritoneal
Mesothelioma
Peritoneal mesothelioma develops in the
peritoneal lining of the abdominal cavity. This is a relatively rare form of
mesothelioma; about 25% of all mesothelioma cases are peritoneal in nature.
Symptoms of peritoneal mesothelioma include
pain or swelling of the abdomen, changes in bowel habits (such as constipation
or diarrhea), unexplained weight loss, and nausea or vomiting. These symptoms
are caused by thickening of peritoneal membranes and fluid build-up, which puts
pressure on internal organs and prevents normal function of some organs. As the
cancer advances, people with peritoneal mesothelioma may notice lumps
developing under the skin of the abdomen.
Diagnosis of peritoneal mesothelioma involves
imaging tests such as CT scans and MRIs, as well as biopsies of fluid and
tissue to detect the presence of mesothelioma cells. There is currently no
recognized staging process for peritoneal mesothelioma.
Peritoneal mesothelioma is problematic in terms
of treatment because the cancer can spread quickly throughout the peritoneum
and often metastasizes more quickly than other types of mesothelioma. In some cases,
surgery is possible, but this is typically a palliative treatment option.
Pericardial Mesothelioma
Pericardial mesothelioma develops in the
membrane that surrounds the heart, also known as the pericardium. This is a
very rare form of mesothelioma, occurring in just 5% of cases. It’s also very
difficult to treat.
Symptoms of pericardial mesothelioma include
irregular heartbeat or palpitations, chest pain, and difficulty breathing.
These are caused by the pressure put on the heart by the build-up of fluid in
the spaces between pericardial membrane layers.
It is very rare for pericardial mesothelioma to
be diagnosed early enough for any form of treatment to be effective, and
pericardial mesothelioma patients typically have an extremely poor prognosis.
In very rare cases, the cancer may be diagnosed early enough for surgery to
have a positive effect; however, the proximity of this cancer to the heart
makes such surgery a high-risk treatment option.
Testicular
Mesothelioma
Testicular mesothelioma is the rarest of all
mesothelioma cancers, with less than 100 cases ever recorded. This type of
mesothelioma develops in the lining that surrounds the testicles, known as the
tunica vaginalis.
Due to the extreme rarity of testicular
mesothelioma, very little has been noted about its symptoms and the treatment
options available. Often, the disease is not diagnosed until patients notice
the appearance of testicular lumps. In some cases, surgery for an unrelated
condition such as a hernia leads to the detection of testicular mesothelioma.
If the primary tumor has developed in the
testicles, treatment involves removal of part or the entire affected testicle,
followed by chemotherapy or radiation therapy. However, often the testicular
tumor is secondary, and the primary cancer is located in the peritoneum. In
these cases, treatment follows established patterns for peritoneal mesothelioma
in addition to removal of testicular tumors.
Pleural
Mesothelioma
Malignant mesothelioma is a rare form of cancer
that can develop in people who are repeatedly exposed to asbestos. About 2,000
to 3,000 Americans are diagnosed with this type of cancer each year. Of those,
around two-thirds have the pleural form of mesothelioma.
Pleural mesothelioma develops in the lining of
the lungs. This lining is called the pleura, or pleural membrane, and it is
made up of mesothelial cells. This pleural membrane consists of two layers —
the parietal layer and the visceral layer. The parietal layer is an outer layer
that lines the entire chest cavity and diaphragm, while the visceral layer is
an inner layer that covers the lungs. Together, these two layers provide
support and protection for the lungs and the chest cavity.
I recommend that if you or someone in your family has a diagnosis of this disease are placed in contact with The Mesothelioma Cancer Center, they have a U.S. phone line 1-800-590-6512. They can give you much information about this topic.
I hope you keep visiting us and I send you a hug
