Can Chest X-Rays Find Lung Cancer Early?

Lung cancer is the #1 cause of cancer death in the USA for both men and women. The vast majority of lung cancer cases are caused by smoking ,thus lung cancer simultaneously represents the most devastating cancer in our society, and the most preventable. There are good screening tests for many types of cancer, such as the pap smear for cervical cancer , the mammogram for breast cancer , and colonoscopy for colorectal cancer.

But lung cancer screening has been at an impasse for almost as long as it has been a possibility. Screening tests are supposed to find diseases before they cause symptoms, but that is just the means to an end. The goal is for fewer people to die from the disease. Several large, well-designed trials of chest x-rays have found that while they do a good job of identifying early lung cancers, that hasn’t translated into fewer deaths.

The drive to test healthy people for common cancers rests on the idea that finding malignancies early can trigger life-saving treatment. But the evidence that some of the tests will actually reduce mortality is sometimes lacking or is less than clear cut for the people who’ll get tested. Now, a big federally funded study finds that yearly chest x-rays to look for lung cancer aren’t worth doing because they don’t save lives.

A chest x-ray might be able to detect esophageal cancer, like it does with lung cancer. However, it is recommended that a person use an esophagram.

X-rays miss up to 23% of incidences of lung cancer in the UK, according to a review published in the British Journal of General Practice. The research team reviewed 21 studies to determine the diagnostic accuracy of chest x-rays, the recommended method for investigating symptoms of lung cancer. Databases including Medline and the Cochrane Library were searched.

Lung cancer makes up one of the main causes of cancer death across the globe. Most of the lung cancer cases are due to smoking. Lung cancer is caused by the cells that do not function normally or grow into an unhealthy tissue. It is recommended that if you feel that you have symptoms of lung cancer, then visit your physician immediately. The doctor is in a better position to evaluate your medical history and assess any of the risk factors at hand. Then if a physical examination is necessary, they may say an x-ray can detect lung cancer.

Lung cancer is one of the few cancers with a well-defined etiology — inhalation of tobacco smoke. Patients at high risk for lung cancer should decide with their clinician whether or not to undergo regular screening. In the case of an abnormal chest x-ray, the patient should undergo a chest CT for further evaluation.

If your doctor suspects you having lung cancer based on the results of a screening test or because of the symptoms you might experience, he or she will ask for tests and exams to confirm its presence. A chest x-ray is often the first test your doctor will do if you experience symptoms that match the signs of lung cancer. X-rays of your chest can be done at imaging centers, hospitals, or even in some doctors’ settings. Sometimes, your doctor may ask for more tests if the x-ray does not clarify completely.

Chest x-rays are typically performed to: investigate symptoms such as shortness of breath, chronic and persistent cough, chest pain, chest injury or fever to monitor the progress of chronic medical conditions such as cancer or heart failure as a screening test for employment, immigration or to join the defence force chest x-rays are also used to disgnose lung issues, bone problems of the chest wall, and some heart problems.

Treatment for lung cancer varies depending on lung cancer type, stage and the patients breathing capacity and general health. Non-small cell lung cancer – is usually treated with surgery if possible. Otherwise radiotherapy and/or chemotherapy is used. Small cell lung cancer – is usually treated with chemotherapy. Radiotherapy to the chest, brain or other sites (known as preventive or prophylactic radiotherapy) may also be recommended as this type of cancer can spread early and surgery is not often used.

See a GP if you have symptoms of lung cancer , such as breathlessness or a persistent cough. The GP will ask about your general health and your symptoms. They may examine you and ask you to breathe into a device called a spirometer , which measures how much air you breathe in and out.

You may need x-rays to check for tumours or damage to the bones. X-rays are quick and painless, and include: orthopantomogram (opg)– used to examine the jaw and teeth of people with mouth cancer chest x-ray – sometimes used to check the general health of people with mouth, pharyngeal or laryngeal cancer, or to see whether the cancer has spread to the lungs. However, most people have a ct or pet–ct scan to look at these areas.

The tests described above help your specialist work out how far the cancer has spread. This is known as staging, and it helps your health care team recommend the best treatment for you. Non-small cell lung cancer and small cell lung cancer can both be staged.

Cancer may make the bone appear different than surrounding healthy bone on an x-ray. The bone may look ragged, or it may appear to have a hole in it. A chest x-ray may also help determine whether cancer cells have spread to the lungs.

Are there any alternatives?

The trickiest part of diagnosing someone with cancer is catching it early enough to effectively treat it. But now, researchers from Johns Hopkins Cancer Center may have a potential solution for spotting the symptoms before they even appear: a simple, noninvasive blood test. In a new study published recently, researchers tested out a screening test that could be used in seemingly healthy people. They developed it by analyzing the blood samples of 200 patients with breast, lung, ovarian, and colorectal cancers for mutations within nearly 60 genes that have been linked to several cancers.
