How Dangerous is “Mesothelium”
Posted by AdminMesothelium
Mesothelioma is a form of cancer that is almost always caused by previous exposure to asbestos. In this disease, malignant cells develop in the mesothelium, a protective lining that covers most of the body's internal organs. Its most common site is the pleura (outer lining of the lungs and chest cavity), but it may also occur in the peritoneum (the lining of the abdominal cavity) or the pericardium (a sac that surrounds the heart).
Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, or have been exposed to asbestos dust and fibre in other ways, such as by washing the clothes of a family member who worked with asbestos, or by home renovation using asbestos cement products. Unlike lung cancer, there is no association between mesothelioma and smoking.
* Mesothelioma: (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum. More than 90% of mesothelioma cases are linked to asbestos exposure.
* Intra-abdominal adhesions: Normally, the mesothelium secrets plasminogen, which removes fibrin deposits. During surgical procedures, the mesothelium may be damaged. Its fibrinlytic capacity becomes insufficient and fibrin accumulates, causing fibrous adhesions between opposing surfaces. These adhesions cause intestinal obstruction and female infertility if it occurs in the abdomen, and may impair cardiac and lung function in the thorax.
* Ultrafiltration failure: The peritoneal mesothelium is implicated in in the long-term development of ultrafiltration failure in peritoneal dialysis patients. The presence of supra-physiological glucose concentrations, acidity, and glucose degradation products in peritoneal dialysis fluids contribute to the fibrosis of the peritoneal mesothelium, either by epithelial-mesenchymal transition or increased proliferation of existing fibroblasts. A fibrosed peritoneum results in the increased passage of solutes across the peritoneum and ultrafiltration failure.
Symptoms Introduction
Cancer often has no specific symptoms, so it is important that you limit your risk factors and undergo appropriate cancer screening.
Nevertheless, you need to know which symptoms might point to cancer. You do not want to ignore a warning that might lead to early diCancer gives you no symptoms or signs that exclusively indicate the disease. Every complaint for cancer can explain a harmless condition as well. If you have symptoms, however, you should see a doctor for further evaluation. Some common symptoms are as follows:
* Persistent cough or blood-tinged saliva
o These symptoms usually represent simple infections such as bronchitis or sinusitis.
o They could be symptoms of cancer of your lung, head, and neck. Anyone with a cough that lasts more than a month or with blood in the mucus that is coughed up should see a doctor.
* A change in bowel habits
o Doctors sometimes see pencil-thin stools with colon cancer.
o Occasionally, cancer exhibits continuous diarrhea.
o Some people with cancer feel as if they need to have a bowel movement and still feel that way after they have had a bowel movement. If any of these abnormal bowel complaints last more than a few days, they require evaluation.
* Blood in your stool
o A doctor always should investigate blood in your stool.
o Hemorrhoids frequently cause rectal bleeding, but because hemorrhoids are so common, they may exist with cancer. Therefore, even when you have hemorrhoids, you should have a doctor examine your entire intestinal tract when you have blood in your bowel movements.
+ X-rays may be enough.
+ Sometimes, when the source of your bleeding is entirely clear, these studies may not be needed.
* Unexplained anemia
o Anemia is a condition in which you have fewer than the expected number of red blood cells in your blood. Anemia should be investigated.
o There are many kinds of anemia, but blood loss almost always causes iron deficiency anemia. Unless there is an obvious source of ongoing blood loss, as there is for menstruating women, this anemia needs to be explained.
o Many cancers can cause anemia, but bowel cancers most commonly cause iron deficiency anemia. Evaluation should include endoscopy or x-ray studies of your upper and lower intestinal tracts.
* Breast lump or breast discharge
o Most breast lumps are noncancerous tumors such as fibroadenomas or cysts. But all breast lumps need to be thoroughly investigated.
+ A negative mammogram result is not sufficient to evaluate a breast lump.
+ Generally, diagnosis requires a needle aspiration or biopsy (a small tissue sample).
+ Discharge from a breast is common. But some forms of discharge may be signs of cancer. If discharge is bloody or from only 1 nipple, further evaluation is recommended.
o Women are advised to conduct monthly breast self-examinations.
* Lumps in the testicles
o Most men (90%) with cancer of the testicle have a painless or uncomfortable lump on a testicle.
o Some men have an enlarged testicle.
o Other conditions, such as infections and swollen veins, can also cause changes in your testicles, but you should have any lump evaluated.
o Men are advised to conduct monthly testicular self-examinations.
* A change in urination
o Urinary symptoms can include frequent urination, small amounts of urine, and slow urine flow.
o These symptoms can be caused by urinary infections or, in men, by an enlarged prostate gland.
+ Most men will suffer from harmless prostate enlargement as they age, and will often have these urinary symptoms.
+ These symptoms may signal prostate cancer.
+ Men experiencing urinary symptoms need a bit of investigation, probably including a specific blood test called a PSA and a digital rectal exam.
o Cancer of the bladder and pelvic tumors can also cause irritation of the bladder and urinary frequency.
* Blood in the urine
o Hematuria or blood in the urine can be caused by urinary infection, kidney stones, or other causes.
o For some people, it is a symptom of cancer of the bladder or kidney.
o Any episode of blood in the urine should be investigated.
* Hoarseness
o Hoarseness not caused by a respiratory infection or that lasts longer than 3-4 weeks should be evaluated.
o Hoarseness can be caused by simple allergy or by vocal cord polyps, but it could also be the first sign of cancer of the throat.
* Persistent lumps or swollen glands
o Lumps most frequently represent harmless conditions. But your doctor should examine any new lump or a lump that won’t go away.
o Lumps may represent cancer or a swollen lymph gland related to cancer.
o Lymph nodes swell from infection and other causes and may take weeks to shrink again.
o A lump or gland that remains swollen for 3-4 weeks should be evaluated.
* Obvious change in a wart or a mole
o Multicolored moles that have irregular edges or bleed may be cancerous.
o Larger moles are more worrisome.
o Removing a mole is simple. You should remove any suspicious mole. The doctor will diagnosis and possibly to a cure.
