Mesothelioma symptoms and signs Lung cancer
Symptoms associated with mesothelioma
A patient with mesothelioma usually begins to show symptoms 15 to 50 years after exposure to asbestos.
It may take decades for cancer to appear in the body and Mesothelioma symptoms and signs Lung cancer do not appear until the time the cancer is developed. Common symptoms in the early stages of mesothelioma include fatigue, coughing, shortness of breath and a noticeable reduction in the capacity of the respiratory system.
Many patients are not aware that they have mesothelioma or the severity of the condition because the initial symptoms are quite similar to those of less serious diseases, and also because they appear long after the initial exposure.
If you have a history of exposure to asbestos, the main cause of mesothelioma cancer, and believe you may be developing mesothelioma symptoms, it is best to seek help right away. Informing your doctor about past exposures can alert the expert to the possibility of some form of asbestos-related disease, such as mesothelioma.
What are the symptoms of pleural mesothelioma?
Most symptoms of pleural mesothelioma are associated with the respiratory system. However, a small number of patients have been diagnosed as widening of the pleura by means of scanning exams that are also indicative of mesothelioma.
The most commonly reported symptoms of pleural mesothelioma include:
- Chest pain
- Difficulty breathing (shortness of breath)
- Expansion of the reduced thoracic cavity
- Difficulty breathing
- Dry cough
- Pleural effusions
These benign lesions may be up to 6 centimeters in diameter and may appear in several places around the pleural and visceral surface of the pleural. In a 2011 study, of 221 patients with pleural mesothelioma, the reported symptoms were as follows:
- 90% of patients had pleural effusions
- 79% of the patients presented short breath
- 64% of patients reported chest pain
- 36% of the patients developed chronic cough
- 30% of the patients presented weight loss
What are the symptoms of other types of mesothelioma?
Abdominal pain is the first symptom for patients with peritoneal mesothelioma. This is usually followed by an enlargement and tenderness of the same. Ascites, the accumulation of fluid between the peritoneum and the abdominal organs, are very common, however these develop in later stages of the disease. In a study of 13 people with peritoneal mesothelioma, 77 percent developed ascites.
Peritoneal mesothelioma is associated with loss of appetite which usually results in weight loss, abdominal distention and abdominal hernias. In one study, 69 percent of patients with peritoneal mesothelioma had weight loss. Patients also noticed changes in their bolus in the late stages of cancer. In addition, an Australian study found that 10 percent of cases of peritoneal mesothelioma suffered from short epilepsy.
- 69% of patients had weight or appetite loss
- 77% of the patients developed ascites
- Abdominal pain is an early sign of peritoneal mesothelioma
- Intestinal obstruction occurs in late stages
There are only a few cases of pericardial mesothelioma and these have reported difficulty breathing and chest pain. These symptoms are the result of widening of the pericardium.
The only constant sign that has occurred in patients with testicular mesothelioma are the lumps in the testicles. This type of mesothelioma is incredibly rare and the more studies are performed more symptoms will be discovered.
What symptoms indicate rapid metastasis?
Not all symptoms of mesothelioma occur in the place where the cancer affects. Symptoms that are closest to the local invasion include:
44% of Mesothelioma Spreads Around Lymphatic Nodes
Local spread to lymph nodes is quite common and occurs in 44% of cases.
- Horner’s Syndrome
- Laryngeal nerve palsy
- Serious problems with nerves in the arms
Paraplegia occurs if the cancer spreads into the spiral canal. A mesothelioma that has metastasized can also clog the superior vena cava. Hypoglycemia has also been reported as a clinical invasion of mesothelioma, but this occurs in fibers located in rare places. Finger splicing and pulmonary hypertrophy Osteoarthropathy are even rarer, but may occur in some cases of malignant mesothelioma and primarily when asbestosis is present.
When do mesothelioma symptoms emerge?
Usually patients with mesothelioma may notice the first symptoms between 30 and 50 years after being exposed to asbestos for the first time. This period of time is not very different between the different types of mesothelioma, however there have been studies that have shown that the initial symptoms appear in a shorter period of time in patients with peritoneal mesothelioma (20 to 30 years) than those who have Contracted pleural mesothelioma. On the other hand, a 20011 study of 191 cases of malignant mesothelioma showed that women have a longer symptom onset period than men.
Mesothelioma Symptoms Timeline
A larger study of 1,690 mesothelioma patients found an average of 32-year-onset symptoms, while an even larger study (5,173 patients) reported an average of 43.6 years. Once the mesothelioma symptoms appear, they are usually quite moderate. Many patients do not even pay attention when symptoms first appear and only seek medical help when they intensify. Additionally, a high percentage of patients with mesothelioma suffer from other types of respiratory diseases and the presence of mesothelioma is usually misinterpreted as a progression from an existing condition, such as chronic pulmonary obstruction.
Due to the fact that symptoms take so long to appear, the disease is not treated correctly in some cases. One study found that the interval between the first presentation of symptoms and the application of appropriate treatment may be up to 38 months.
