Lung Cancer Diagnosis and Treatment

Lung cancer is a fatal disease, but new treatments can help patients be able to live if diagnosed early. Your doctor could use a variety tests to diagnose lung cancer.

Imaging tests (Xray, CT scan, MRI, and PET scan) show tumors. A bronchoscope may be used to collect a sample of tissue from the lungs.

Diagnosis

Your doctor may employ a variety of methods to study lung masses more closely, and also collect samples of tissue or fluid to be tested (biopsy). A needle biopsy, in which an radiologist directs a needle using X-rays or CT images to a mass on the chest wall, can diagnose cancer as high as 90 percent of the time.

The doctor can also conduct the sputum cytology test where he or she analyzes the mucus that is produced by your lungs to look for cancer cells. This test can identify 75% of tumors that are found in the bronchi and 25 percent in the bronchioles.

A small portion of the tissue surrounding your lungs and chest wall -- the pleura -- can be analyzed for cancerous cells using a procedure called a thoracentesis. The results of this test could aid your doctor to determine if cancer has developed from the lungs to the pleura and other organs.

The tests for blood don't reveal the presence of cancer, but they may be done to check your overall health and to check how the cancer is responding to treatment. Your doctor may also recommend an PET/CT scan to obtain more information about the cancer and the cells that are involved, and to find out whether the cancer has been able to spread. This may be done after or prior to a biopsy.

Treatment

Lung cancer is treated by surgery to remove cancerous tissue, radiation to kill cancerous cells, or medications which stop cancer cells from growing. The kind of treatment your doctor recommends will depend on the extent of your lung cancer and its spread as well as your general health.

To confirm the diagnosis of lung carcinoma, a sample of tissue (biopsy), may be required. Your doctor can take the tissue sample with an bronchoscope. they pass a thin tube through your throat and into your lung. If the cancerous lung is located close to your windpipes or bronchial tubes, a test called sputum-cytology can identify it by studying a sample sputum under microscope.

If the biopsy indicates that the cancer has spread to other areas the test is called staging. It is used to determine how far the cancer has advanced. Staging will aid your doctor decide on the treatment that is the best one for you. The staging is usually given as a digit in the form of a roman number ranging between 1 and 4. The number 0 indicates that the cancer has been confined to the lung, while 4 indicates that it has spread to nearby nodes or other organs of the body, including the bones, the liver or the adrenal glands.

Researchers are studying new treatment options for lung cancer including combinations of chemotherapy with new kinds of radiation. Researchers are also working on ways to make tumors more sensitive to radiation or drugs that kill cancer cells without harming healthy tissue.

Follow-up

All cancer survivors need follow-up treatment following treatment. This involves regular medical examinations and tests, which can be done to look for issues that may arise months or years after the end of treatment for cancer.

It is essential for patients with lung cancer to keep in touch with their healthcare providers. These visits help them remain healthy and spot any issues that require immediate treatment.

A doctor that is familiar with the person's medical history can help them decide what follow-up testing is needed. The tests are typically blood tests, but they may also include x rays and CT scanners. In some instances doctors may also perform a biopsy.

A few people who have lung carcinoma may suffer an occurrence of recurrence. This means that the cancer recurrs and re-infects that same area of the lung, or in other places in the body. People with recurrent tumors often do not show any symptoms initially however it is difficult to tell if the cancer is coming back.

For this reason, Lung Cancer Case doctors suggest that future scans be conducted to look for any recurrence. Doctors advise that patients suffering from non-small cell lung cancer (NSCLC) in stages I to III undergo an abdominal CT once every six months for the first two years following treatment.

These regular checkups help detect any changes in a person's health such as a swelling or lump. The person's health care provider will then determine whether the problem stems from cancer that has come back or because of the side effects of treatment.

Prevention

Although there is no cure for all cancers but preventive actions can help you live longer. The most important thing to do is avoid tobacco and secondhand smoke, limit exposure to radon, diesel exhaust as well as other air pollutants. Also, take regular tests for lung cancer.

Screening helps detect cancers at an early stage that makes them easier to treat. Your doctor will examine your breathing and listen to your lungs. They may also recommend a blood test, an image scan or computed Tomography (CT scan). They can also collect samples of lung tissue to look for signs of lung cancer.

Lung cancer is traditionally categorized by where it begins in the lungs. However doctors are now able to diagnose lung cancer case (mouse click the following web page) cancer on molecular levels. This kind of diagnosis typically involves looking at DNA or proteins that cancer cells produce. Variations in the EGFR gene, ALK gene, KRAS gene and ROS1 gene can alter the rate at which tumors grow or spread. These mutations can affect which treatments are best for the patient.

If lung cancer is discovered The next step is to find out if it has spread, or metastasized or metastasized to other parts of the body. These tests include chest x-rays and a bronchoscopy. They can also be a CT scan or a PET/CT scan.
