Symptoms
of mesothelioma cancer are not being shown immediately after the body
is infected with the disease, but mostly 20-40 years after that, due to
the long "incubating" period of the disease.
Mesothelioma
is sometimes diagnosed by coincidence, before there are any shown
symptoms. For instance, tumors have been discovered through routine
chest x-rays. However, when symptoms occur, they may include shortness
of breath, weakness, loss of appetite, chest pains, lower back pains,
persistent coughing, difficulty in swallowing, alone or in combination.
On the other hand,
some patients that may not show any significant symptoms at all, and
that is why it is so important for people which were exposed to
asbestos, to have proper diagnostics.
An
initial medical examination often shows a pleural effusion, which means
an accumulation of fluid in the pleural space - the area between the
lungs and the chest wall. The above mentioned coughing and chest pains
are the results of this fluid accumulation in the pleural space.
Fluid
build-up from the pleural effusion can generally be seen on a chest
x-ray and heard during a physical examination, but a firm diagnosis of
mesothelioma can only be made through a biopsy and pathological
testing. This is important because there are also benign pleural
effusions and other tumors that have a similar appearance to
mesothelioma tumor. Diagnosing mesothelioma lung cancer can be quite
difficult; it requires special lab stains, and much experience in
understanding them. Pleural mesothelioma
starts in the chest cavity and can then spread to other parts of the
body. People who suffer from this disease may also begin to display
severe breathing difficulty, weight loss and fever as well as trouble
swallowing and even swelling of the face and neck. Some patients may
also develop a rasping voice and start coughing up blood.
The symptoms for patients who suffer from peritoneal mesothelioma are a sometimes different. This type of mesothelioma cancer starts in
the abdomen and can spread form there. Patients of peritoneal
mesothelioma can display abdominal pain and swelling, nausea, loss of
appetite and vomiting. Some patients also experience breathing
problems, and chest pain in addition to these symptoms. These symptoms
result from tumours that lean against the abdominal wall. Bowel
obstruction, anaemia, fever and problems with blood clotting may also
affect peritoneal mesothelioma patients.
The third form, and the most uncommon among mesotheliomas, pericardial mesothelioma,
starts in the cavity surrounding the heart. With pericardial
mesothelioma, the tumours grow in the tissues that surround the heart
and can spread from there. Pericardial mesothelioma sufferers may
experience chest pain, shortness of breath, persistent coughing and
palpitations.
