Mesothelioma lung cancer vs. Adenocarcinoma lung cancer explained
Mesothelioma Lung Cancer
A mesothelioma is a form of cancer almost exclusively related to exposure to asbestos. It is the result of asbestos fibers becoming lodged in the pleura, which is the outer lining of the lungs. This causes an irritation to the mesothelium, a protective lining the covers the lungs, which then causes the mesothelial cells to proliferate, resulting in a cancerous growth commonly referred to as mesothelioma, or mesothelioma lung cancer.
Mesothelioma is most commonly observed in those who have worked around asbestos for a prolonged period. Smoking dramatically increases the risk of developing mesothelioma, however, it is not the cause of mesothelioma.
Mesothelioma is diagnosed through a combination of medical history, imaging technologies like x-rays, MRIs and CAT scans, and biopsy and tissue sampling. Anyone who experienced prolonged exposure to asbestos should have regular screenings for lung abnormalities, as the incubation period between exposure and development of lung cancer can be as long as 50 years.
Prevalence of Mesothelioma
Mesothelioma is most prevalent among those who have had significant exposure to asbestos and other clouds of dust. These include but at not limited to: brake mechanics, construction and sheet metal workers, plumbers, steamfitters, insulators, carpenters, plumbers, etc.
Symptoms of Mesothelioma
An individual suffering from mesothelioma will often experience labored breathing, fever, coughing, shortness of breath and chest pain as the initial symptoms of the disease. Since most of the medical professionals are not experienced in this disease, these symptoms can be misinterpreted as indications of other diseases. Confirmation of mesothelioma is achieved by examining the pleural fluid or biopsy of the pleural membrane.
Diagnosis of Mesothelioma
Recently, Australian researchers have developed a world-first non-invasive blood test for early recognition of mesothelioma. More commonly, however, the diagnosis of mesothelioma is a long process that includes blood tests, CT scans, drainage, biopsy, laboratory analysis of pleural fluid and chest X-rays. Once the disease is suspected through imaging tests, the tissue is removed and examined by a pathologist, who will make a definitive diagnosis.
Treatment of Mesothelioma
As with other cancers, the treatment for mesothelioma depends on factors such as the stage of cancer, the location of cancer and the extent to which it’s spread, the patient’s age, and the prognosis. Currently, the five-year survival rate is approaching approximately 12%.
Traditional treatment options include surgery, chemotherapy, and radiation, or a combination of these. Upcoming treatments that are still in the experimental stages include photodynamic therapy (a treatment that uses a photosensitizer drug or photosensitizing agent that when are exposed to a specific wavelength of light, produce a form of oxygen that kills nearby cells) and immunotherapy (utilizing the body’s natural tendency to defend itself against cancerous tumors).
Although their treatment options available for mesothelioma, the overall success rate is not good. As with any cancer, the earlier it’s caught, the better the chances for survival.
Adenocarcinoma lung cancer
Adenocarcinoma lung cancer is considered a complicated form of lung cancer because of its extensive presence in the pulmonary regions which inevitably affects the functions of the lungs. Any adenocarcinoma tumor is given clinical emphasis primarily because of its pathogenic effects. A vigorous clinical approach is vital to the potential recovery of the patient.
Experienced medical experts in the field of oncology classify adenocarcinoma lung cancer as metastatic cancer. This is why even when cancerous cells are encountered in a patient additional clinical work is often required to determine if the origin of the cancer was in the pulmonary regions. As a result, it’s routine to investigate the status of such organs as the uterus, the ovary, and the thyroid to better determine the origin of cancer.
Most neoplasms (any new and abnormal growth in which the growth is uncontrolled and progressive) of the pulmonary regions, such as in the case of adenocarcinoma, reflect problematic metastatic processes. Thus the clinical approach (comprised of chemotherapy, supportive therapy, radiation therapy, etc.) is considered complicated for those patients facing adenocarcinoma lung cancer.
Further, it’s noteworthy that cases of adenocarcinoma lung cancer are grouped under pulmonary neoplasms that have epithelial (layers of cells that provide protection for the body) origin, unlike hemangioma (abnormally dense collections of dilated small blood vessels that may occur in the skin or internal organs), etc. This adenocarcinoma is always considered as a malignant form of pulmonary neoplasm.
Symptoms of Adenocarcinoma Lung Cancer
Patients affected with adenocarcinoma lung cancer often experience intense bouts of pain and difficulties in a respiratory activity called Dyspnea that may also produce a cough. This condition will generally not improve, even with therapy to counteract the generalized infection.
Hence, if the treatment to ameliorate a respiratory infection proves ineffective, the patient should be referred to a clinical oncologist to rule out the possibility of any underlying conditions such as this form of lung cancer.
Since adenocarcinoma lung cancer therapy may involve specific alternative pulmonary neoplasm treatment, affected patients may have to look into the advanced therapies such as nutritional approaches or laser beam based approaches.
Remission of this form of adenocarcinoma largely depends on how early the specialized therapy is initiated. It may also depend on the side effects of the medicament, as well as the toxic effects, and of course the overall safety of the medical approach. Both patient and doctor will likely be taking extreme measures in order to ameliorate the increasing signs of pain etc.
Chemotherapy for adenocarcinoma lung cancer often involves a combination of multiple drugs and additional supportive therapies with drugs such as prednisolone, flunixin, meglumine, etc. However, one needs to understand the pharmacological effects of such drugs on the lungs. These medications require clinical precautions.
Patients need to be well informed of the potential impact they may have on any anti-cancer therapy treatments in dealing with adenocarcinoma lung cancer.
