Stomach Cancer - Diagnosing Cancer of the Stomach Muscle


Stomach cancer symptoms tend, at the beginning, to be very vague. Every year 21,520 people are diagnosed with about 10,340 of them dying from it. The majority of sufferers are men, and the average age when the disease is detected is around 70. The risk is higher in people who smoke, have been infected by the helicobacter pylori bacteria and developed ulcers from the infection, eat a diet high in foods that are salted, pickled or processed, like bacon or cured ham, and have close relatives who've had stomach cancer. Other risk factors are blood type, as people with Type A blood have a slightly higher risk for getting the disease. Alcoholics, or people who have a heavy alcohol consumption, are also more at risk. Other factors are gastritis, or stomach inflammation, decreased stomach acid, and having part of the stomach removed surgically.

Stomach cancer is the fourth leading cancer in the world and is the second cause of cancer related death after lung cancer. It's not as common in the United States as it is in other countries, particularly Asian countries.

Signs and Stomach Cancer Symptoms

The most common victims of stomach cancer are men over 65. The condition, like so many conditions that involve the digestive tract, is difficult to diagnose in its early stage because stomach cancer symptoms are nonspecific. This means they could be anything from indigestion to the beginnings of cancer. In stomach cancer's earliest stages there may be no symptoms at all, or the vague symptoms of indigestion, such as fullness, burping, nausea and decreased appetite. By the time these symptoms occur, the cancer may already have spread to the bones, liver or lungs.

Later symptoms are unexplained weight loss, fatigue, and vomiting blood that resembles coffee grinds. The person may pass black, tarry stools, which indicates blood in them. They may feel full after eating only small amounts of food. They may suffer from anemia from internal blood loss and have pain or discomfort in the upper part of the abdomen. They may or may not be able to feel a mass in the same area.

Diagnostic Tests for Stomach Cancer Symptoms

A person who suspects they have stomach cancer may have medical exams that include laboratory studies of the blood for anemia, and an endoscopy, when a thin tube is inserted down the esophagus and into the stomach. Biopsies are then taken of any suspicious looking growths. They might also be subject to X-rays and other tests that produce images of the interior of the body. They may take a GI series, which may include a barium enema, ultrasounds, CAT and/or MRI scans, or PET scans. Treatments can include surgery, including the less invasive laparoscopic surgery, radiation, immunotherapy and chemotherapy, or a combination of these methods.

Because stomach cancer is usually discovered late, the prognosis for complete recovery is poor. The survival rate of people who are diagnosed with Stage IV stomach cancer is only about four percent. However, if the condition is discovered early, the survival rate over five years is about 65 percent. This is why doctors say that people who are having symptoms of indigestion or ulcer for more than a few days should contact them, for the symptoms may or may not be cancer related.

Diagnosing Pleural Mesothelioma - A Malignant Disease!


Similar with other types of lung cancer, diagnosing pleural mesothelioma is such a complex job for doctors since symptoms do not usually take place for some time after primary asbestos exposure. Furthermore, since the indications of malignant pleural mesothelioma are distinctive to many ailments, in the premature stages of the cancer, the symptoms are frequently mistaken for less aggressive diseases such as pneumonia and influenza.

Diagnosing pleural mesothelioma is made partially on the origin of the symptoms but additional diagnostic tests are needed to confirm the presence of cancer. If the doctor suspects an asbestos-related disease, the next step for the diagnosis is testing to confirm the presence of this asbestos cancer, verify the location, size and type of the cancer involved, and to know whether the cancer has already spread to the other parts of the body.

Typical imaging tests involved are the:

* X- ray - most commonly used imaging test for the diagnosis of mesothelioma.

* Computerized Tomography (CT) Scan - it is an x-ray like procedure in which numerous x-ray pictures are taken and combined with a computer to create a thorough image of body tissues. When you undergo a CT scan, you may be given an injection of dye, which helps produce more concrete images. It may not only show the effusion but as well as the presence of pleural masses.

* Positron Emission Tomography (PET) Scan - this is a highly sensitive scanner that detects the metabolic signal of progressive cancer cells in the body and can help staging the cancer. Glucose solution is being controlled by an intravenous injection. Malignant cells get up and use sugars more quickly than normal cells, so they can be easily noted using the procedure.

* Magnetic Resonance Imaging (MRI) - is a combination of strong magnetic field and radio waves and is much more sensitive in determining chest wall invasion and the multiplication of the disease. It is also used to create detailed three-dimensional images that can be warily examined by a radiologist.

After diagnosing pleural mesothelioma, your physician will generally recommend an oncologist, a cancer specialist, who is well versed in treating the disease and who will help determine the best alternative for your mesothelioma treatment.

Diagnosing Lung Cancer For Successful Treatments


Prior to treatment of any medical condition, there must first be a diagnosis and in the instance of lung cancer, there are numerous tools available to assist in diagnosis of the condition. Once a diagnosis has been completed, the stage of the lung cancer must then be determined in order to effectively choose a treatment option - this is known as "staging."

It is usually the case that a patient discovers an abnormality as a result of a routine x-ray check-up or as a consequence of symptoms appearing which cause them to seek medical advice. Typical symptoms include a persistent cough or the production of blood when coughing, but it is important to remember that there are other causes aside from lung cancer which may produce these symptoms.

To confirm what an abnormality is, your medical team will call on some or all of the following diagnostic techniques:

CT Scan - CT stands for "Computed Tomography" and uses x-rays to provide a detailed picture of your anatomy. There is no surgery involved and the procedure is completely free of pain.

PET Scan - PET stands for "Positive Emission Tomography" and is another non-invasive diagnostic tool which provides a detailed representation of the abnormality and an indication as to whether it is malignant or not. Cancer tumors use a lot of energy, in medical terms they demonstrate high rates of metabolic activity and this requires a lot of nutrition in the form of sugars. By injecting into the patient a glucose solution which is laced with a mildly radioactive marker, the PET Scan is able to highlight where the glucose solution is being concentrated - this provides an outline of the extent of the abnormality and as the lungs are mostly air (which has no metabolism), it provides a precise location of the tumor. You should be aware that a positive result from a PET Scan is not conclusive evidence of cancer because other conditions can create high metabolic activity which will show up on the PET Scan, for instance, inflammation of the lung tissues.

Bronchoscopy - tissue samples or swabs of the major airways can be taken by inserting a flexible tube containing optical fibers and a camera. The tube is inserted either through the nose or mouth and can be mildly discomforting for patients but requires no surgery. The tissue samples collected can then be analyzed in the pathology lab to confirm or rule out cancer.

Needle Biopsy - by using a CT scan to target the general area of the abnormality, a surgeon can insert a needle into the affected area of the lung and remove a tissue sample. Again, the sample can be tested to confirm or discount the presence of cancer in the patient.

Surgical Biopsy - if the abnormality is small or located in an inaccessible part of the lungs then a needle biopsy may not be appropriate and surgery may be required. The surgeon makes two small incisions and using specialist instruments is able to remove a portion of the lung containing the affected tissue. The sample is then analyzed to confirm the diagnosis.




Find the right doctor for lung cancer treatments or mitral valve repair. Early diagnosis can lead to successful results.

Diagnosing Lung Cancer Early Increases Your Chances of Survival


Lung cancer is the fastest growing smoking related disease in the world, it is also the fastest growing cancer with almost a million people being diagnosed every year around the world. This kind of growth is cause for alarm, to be sure, but even more alarming is the fact that symptoms do not usually occur to suggest lung cancer until it has progressed beyond a surgically treatable option. When it comes to diagnosing lung cancer there are many options. However, until a doctor has reason to believe that a patient has this disease, there is seldom a reason to run any of these tests creating a situation where the disease has to progress substantially before a diagnosis is made.

The most common way of diagnosing lung cancer is via a chest x-ray. Generally the chest x-ray is order to determine the cause of pneumonia which often results in the discovery this disease, especially in the case of recurring pneumonia in the same section of the lungs. While this is a good way to diagnose cancer, the x-ray is not infallible and can only see masses in front of bones, not behind, so it is not 100% accurate in its diagnosis.

Another common, but less common than x-ray, way for diagnosing lung cancer is with a CT or more commonly known CAT scan. This scan allows doctors to see the smaller masses that an x-ray simply cannot see. The CAT scan is a better technology for this discovery, however it is also more expensive so it is not used without a good cause. The CAT scan can also help doctors determine how far the cancer has spread, and to where.

PET scans and MRI's are excellent ways to check for cancer, however, once again, they are not generally used for the diagnosis of lung cancer, instead they are used to determine the spread of the disease and a PET scan can help doctors establish the amount of cancerous tumors a person has in their body because of a special sugar injected into the body.

Once tumors are found on a persons lungs or throughout the body, diagnosing lung cancer becomes a matter of taking a biopsy. A biopsy is the removal of some of the suspected tissue from the persons body. It is then observed under a microscope to determine if it is a cancerous mass and if it is, what kind of cancer it might be.

The sooner it is diagnosed the better the prognosis for the patient. It is important for anyone who has been exposed to cancer causing agents or who smoke to have themselves checked out for cancer whether they have symptoms or not. If they wait until symptoms occur, it might be too late.
