Mesotheliona Staging
Mesothelioma tend to grow and spread in unusual ways compared
to other tumors. Rather than forming a "lump", mesothelioma
tends to extent from the pleural lining to press against the
lung or abdominal organs. It also grows along the pleural
lining, eventually forming a hard casing around the lung and
making it difficult for patients to take a deep breath. Mesothelioma generally does not spread widely to other organs but, rather,
tends to extensively involve the chest and lungs or abdominal
cavity before spreading to other distant organs, late in the
course of the disease.
If the disease is detected early, when
only limited growth on the pleural lining has occurred (stage
I), the tumor is considered potentially curable and an attempt
can be made to surgically remove the entire tumor. Usually,
however, the tumor is detected later, when it more extensively
involves the pleural lining and has possibly invaded surrounding
normal structures. In these advanced stages (stages II, III
and IV), the cancer significantly impacts the quality of life.
