Diagnosing Mesothelioma
The diagnosis of mesothelioma is not always
easy. Many doctors are still unfamiliar with the symptoms which could be put
down to a number of other, more common diseases. Timely diagnosis of
mesothelioma is particularly difficult because of the latency period
between contraction and display of symptoms. The symptoms of this cancer may not
become evident for decades, which means that by the time it is diagnosed it is
in its latter stages and there is little that can be done for the patient.
There are many symptoms that become evident
in Pleural mesothelioma patients, many of which are common symptoms in a
variety of illnesses and diseases, hence the difficulty in diagnosis. Lower back
pain, chest pain and shortness of breath are symptoms of the disease. Some
patients also suffer from excessive perspiration, trouble swallowing, weight
loss and tiredness. The disease affects the respiratory system, and results from
an accumulation of fluid between the lung lining and chest cavity, known as
pleural effusion. The other type of mesothelioma, which affects the abdominal
lining, is known as peritoneal mesothelioma. The symptoms that may be
displayed by patients include nausea, vomiting, weight loss and stomach
pains.
The diagnosis of mesothelioma will entail
scans and biopsies arranged by your doctor. A CT or MRI scan is often used to
detect the possible presence of the disease, and if there is a positive
indication of the presence of mesothelioma, the scans are followed up by
a biopsy. Doctors often run an examination on the fluid surrounding the lungs,
but all too often this is inadequate to make a firm diagnosis. In these
circumstances the doctor may perform a small operation in order to remove a
tissue sample and run a biopsy on that. This is known as open pleural biopsy. If
you are suspected of suffering from peritoneal mesothelioma the biopsy
will be performed on tissue taken from the abdominal area, known as a peritoneal
biopsy.
Although the open biopsy procedures are considered to be the most effective
and conclusive ways of diagnosing mesothelioma according to experts,
there are a range of other procedures that doctors may use in order to try and
determine whether a patient has the disease.
The testing procedure will start with
imaging tests, such as x-rays, CT scans or MRI scans. This will enable the
doctor to view the potentially affected area and make a preliminary diagnosis
and decide upon the best course of action. The doctor may then use a needle to
remove fluid from the affected area and conduct tests to see whether there are
any malignant cells present. However, this test is widely thought of as
inconclusive and many doctors prefer to follow it up with a tissue biopsy
whether or not malignant cells are present.
There are several ways in which the doctor
can perform a tissue biopsy in order to test for mesothelioma. A
thoracoscopy or laparoscopy entails making a small incision and using a tiny
camera to look at the affected area. At this time a small tissue sample can be
taken, which is then examined by a pathologist for signs of mesothelioma.
Your doctor may decide to do a needle biopsy, where a hollow needle is inserted
through the skin and into the chest cavity. The doctor is able to collect a
tissue sample with the needle, and this is then examined by the pathologist.
However, most physicians prefer to use an
open biopsy as this allows for the collection of a bigger tissue sample making
diagnosis easier and more accurate. Once the tissue samples have been collected,
a detailed examination of the cells is performed to check for malignant cells in
the tissue. Once a diagnosis has been made, further scans may be required to
learn the extent of the disease and prescribe treatment.
If you have worked with or had contact with
asbestos at any time in your life, it is important that you let your doctor
know. The difficulty in diagnosing mesothelioma means that you doctor may
put your symptoms down to any number of diseases before testing for
mesothelioma. However, if you have already made it known that you have worked
with asbestos, it will give the doctor a head start in making a diagnosis. This
means that test can be carried out far earlier and the necessary treatment can
be prescribed.
