Lung Cancer Symptom

Doctors emphasize that while the overall survival rate for lung cancer in the bar five years is only 15% survival rate for those whose cancer is diagnosed early and treated surgically high as 80%. For this reason, someDoctors recommend regular cancer screening with chest radiography.

Once the disease has progressed in some way, it spreads rapidly to other parts of the body and lungs to all organs. At this point, surgery is not the most viable treatment method.

Unfortunately, the early stages of lung cancer does not give rise to alarming symptoms. The most common symptoms include persistent cough, a tendency to respiratory Disease, etc. These symptoms are not related to lung cancer. Therefore, the lung cancer is rarely diagnosed until it is too late.

In this context, regular screening for lung cancer - most of the development of tobacco use - as a reasonable choice seems to be, at least for those. But, unlike the case with many other diseases (including cancer, etc.), there is no really effective screening test> Lung cancer.

In most cases, lung cancer was found when doing tests like chest X-rays for other medical problems. Because of the risks that most doctors do not recommend a chest radiograph as a method for routine screening. Many believed (until recently) that the X-ray images of breast cancer can be very misleading, if it is detected.

This conclusion is based on studies in 1970 were. These studies have shown that chest radiographs are noteffective in detecting dangerous, fast-spreading tumors at an early stage. So, those who were found to undergo a relatively slow-growing tumors, surgery and other treatments that are not needed.

However, much has changed since the studies. Today, X-rays are much more sensitive than at the time. In addition, there are a series of sophisticated tests are available, with follow-up can be detected problems with thex-ray.

A new study by adults, the National Cancer Institute, a group of 150,000 healthy. This study, sponsored by the U.S. government announced that 150,000 people in two equal groups - one group is a year of X-rays, while the others (forming the control group) did not receive such screening.

Preliminary results show that the doctors discovered something abnormal in nearly 6,000 people. They were followed by several CTX-rays and other diagnostic tests. Among these 206 men had biopsies. Finally, 126 people diagnosed with cancer. This is only 2.1% of the original 6,000 to anomalies in the X-rays.

The bad news is that 6000 represents a large number of false positives. Has led to unnecessary follow-up X-rays, CT scans, etc. The good news is that cancer is detected with 44% were completely in the early stages of the disease - theThe cancer is very treatable and chances of survival are higher.

The final results of this ongoing study will be available for several years. But according to preliminary results have shown that regular chest X-ray cancer can help in early disease and a cure rate better.
