Mesothelioma Diagnosis: What You Need To Know

October 9th, 2010 No comments

If the chest x-ray is suggestive of malignant mesothelioma, it is likely that further investigations will be ordered, especially if compensation may be sought.


These investigations may include additional imaging studies, blood tests, bone scans, and lung-function tests, as well as more invasive procedures such as thoracentesis, thoracoscopy, pleuroscopy or a lung biopsy. This is a typical mesothelioma diagnosis


Mesothelioma diagnosis can be done through chest x-ray. The typical abnormalities seen on chest x-ray in patients with malignant mesohtelioma are pleural effusion (a collection of fluid in the space between the 2 layers of the pleura), or it is called pleural thickening.


Unlike lung cancer, there is no association between mesothelioma and smoking Malignancies involving mesothelial cells in these spread cavities are known as malignant mesothelioma, which may be localized or diffuse. Mesothelioma is the word used to describe a cancerous tumor that involves the mesothelial cells of an organ, often the lungs, heart, or abdominal organs.


Mesothelioma diagnosis in this disease, malignant cells develop in the mesothelium, a protective lining that covers transcendently of the spread’s internal organs. Greatest malignant mesothelioma set up complex karyotypes, with extensive aneuploidy and rearrangement of tons chromosomes.


Symptoms of mesothelioma may not appear until 20 to 50 years after exposure to asbestos. Mesothelioma diagnosis is often difficult, because the symptoms are similar to those of a number of other conditions. A history of exposure to asbestos may increase clinical suspicion for mesothelioma.


A physical examination is performed, followed by chest X-ray and often lung function tests. The X-ray may reveal pleural thickening commonly seen after asbestos exposure if mesothelioma diagnosis is done.


If the cancer has length beyond the mesothelium to other parts of the size, symptoms may include pain, trouble swallowing, or swelling of the neck or engage.

Symptoms of peritoneal mesothelioma include weight loss and cachexia, abdominal swelling and suffering due to ascites (a buildup of fluid in the abdominal cavity).


Exposure to airborne asbestos particles increases one’s risk of developing malignant mesothelioma.


Mesothelioma diagnosis of malignant mesothelioma has a peak incidence 35-45 years after asbestos exposure. Malignant mesothelioma is a rare type of cancer in which malignant cells are found in the sac lining the chest or abdomen. Most people with malignant mesothelioma have on worked on jobs where they breathed asbestos.


It can also occur in children; however, these cases are not thought to be associated with asbestos exposure.


Most people who develop mesothelioma get worked on jobs where they inhaled asbestos particles, or have been exposed to asbestos dust and fiber 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.


Treatment options a mesothelioma diagnosis for the management of malignant mesothelioma includes surgery, chemotherapy, radiation, and multimodality treatment. Surgery in victims with disease confined to the pleural space is reasonable.


Extrapleural pneumonectomy is a more extensive procedure and has a higher mortality rate. Recently, the mortality rate has been lowered to 3.8%. It involves dissection of the parietal pleura; division of the pulmonary vessels; and en bloc resection of the lung, pleura, pericardium, and diaphragm followed by reconstruction. It provides the greatest local control because it removes the entire pleural sac along with the lung parenchyma.


The 2 surgical procedures used are pleurectomy with decortication and extrapleural pneumonectomy.

Surgical resection has been relied upon because radiation and chemotherapy get hold of been ineffective unequivocal treatments. There are now a number of cancer treatment options open to mesothelioma patients. Extrapleural pneumonectomy for selected victims with very early stage disease may expand recurrence-free survival, but the impact it has on overall survival is unknown at this time.


Mesothelioma diagnosis can be intimidating and can scare a lot of people, but mesothelioma diagnosis may give you a fighting chance if can be diagnose early. So do yourself a favor if you think that what you are suffering from and had worked in an asbestos related workplace.


The purpose of such investigations in mesothelioma diagnosis is to confirm and to determine the type of mesothelioma, to ‘stage’ the disease (measure how severe it is), and so to assess whether the disease is operable.

Colon Cancer – Diagnosis, Causes, Symptoms, Treatement, and Prognosis

October 7th, 2010 No comments

Colon cancer is cancer of the large intestine (colon), the lower part of your digestive system. Colon cancer is the second most common cancer in the USA with equal distribution between men and women. Colon tumors usually affect people over the age of 40, with the majority of people who are diagnosed with the condition being over 60 years of age. Colon cancer may affect any racial or ethnic group; however, some studies suggest that Americans of northern European heritage have a higher-than-average risk of colon tumours.

INCIDENCE OF COLON CANCER

Colon cancer is more common in industrialized nations and in those societies where red meat is a major part of the diet, although evidence tends to suggest that merely changing your diet to white meat and seafood as in for instance Japan, tends to just swap stomach cancer for colon cancer. In almost all cases colon cancer is a treatable disease if caught early.

SIGNS AND SYMPTOMS

Colon cancer usually begins with the appearance of benign growths such as polyps. Often there are no early symptoms. If signs and symptoms of colon cancer do appear, they may include: a change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool for more than a couple of weeks, rectal bleeding or blood in your stool, persistent abdominal discomfort, such as cramps, gas or pain, abdominal pain with a bowel movement, a feeling that your bowel doesn’t empty completely, weakness or fatigue and unexplained weight loss.

CAUSES OF COLON CANCER

Colon cancer’s exact cause is unknown, but it appears to be influenced by both inherited and environmental factors. Studies show a concentration in areas of higher economic development suggesting a relationship to diet, particularly excess animal fat and low fiber. Other factors that increase the risk of developing colon tumors are: age over 40, the presence of other diseases of the digestive tract, family history and ulcerative colitis.

Development of colon cancer at an early age, or at multiple sites, or recurrent colon cancer, suggests a genetically transmitted form of the disease as opposed to the sporadic form. There also is a slight increased risk for colon carcinoma in the individual who smokes.

The most common colon cancer cell type is adenocarcinoma which accounts for 95% of cases.

DIAGNOSIS

The development of polyps of the colon usually precedes the development of colon cancer by five or more years. The American Gastroenterologial Association revised its screening guidelines in 2003 to recommend that people with two or more first-degree relatives with colorectal cancer or a first-degree relative with colon or rectal cancer before age 60 should have a screening colonoscopy beginning at age 40 or beginning 10 years prior to the age of the earlier colon cancer diagnosis in their family (whichever is earliest). Those with a first-degree relative diagnosed with colon cancer after age 60 or two second-degree relative with colon or rectal cancer should begin screening at age 40 with one of the methods listed above, such as annual sigmoidoscopy. The most common colon cancer screening tests are colonoscopy, sigmoidoscopy, and fecal occult blood test.

CT scans and Barium enemas are also routinely used for diagnosis of colon and rectal cancers.

TREATMENT OF COLON CANCER

Almost all colon tumors are treated with surgery first, regardless of stage. The malignant tumor, adjacent tissues and any lymph nodes that may contain cancer cells are removed.

In colon cancer, chemotherapy after surgery is usually only given if the cancer has spread to the lymph nodes (Stage III). Radiation therapy may also be used to induce tumor regression. As with other cancer treatments, the incidence of side effects varies with patient health and the exact nature of the treatment.

PREVENTION

There is not an absolute method for preventing colon cancer. Still, there are steps an individual can take to dramatically lessen the risk or to identify the precursors of colon cancer so that it does not manifest itself. People who turn age 50, and all of those with a history of colon cancer in their families, should speak with their physicians about the most recent screening recommendations from physician and cancer organizations. They should watch for symptoms and attend all recommended screenings to increase the likelihood of catching colon cancer early. Exercise is believed to reduce the risk of colon cancer. Apparently, no association exists between frequency of bowel movement or laxative use and risk of colon cancer.

PROGNOSIS

Prognosis depends on the stage of the disease and the overall health of the patient. If diagnosed early, before the tumor has spread from the bowel, these treatments are very effective, with about 90% of patients alive five years after diagnosis. If the colon cancer does not come back (recur) within 5 years, it is considered cured. Prognosis is poor in patients with liver and lung metastases.
