According to the National Institute of Cancer, in 2020 228,820 new cases of pulmonary cancer will be produced in the United States and 135,720 people will die for this cause. Around 90 per cent of the cases incurred by people who smoke, and the risk of actual smoking cessation of the disease is approximately 20 times that of the mayor and no smokers.
Only 20.5 per cent of patients sobreviven five years after diagnosis. The Mayor of cases is diagnosed late, when the cancer has spread to extenders. But if it is detected and treated in time, it is possible to cure, say the doctors.
The computerized tomography exam is very risky, and the doctors say that they explain it to the patients, who can decide to take the test. The explorations detect tiny nodules in the pulses that can or will not be incurable. Según Park, a suspenseful aspect can only be a small infection, an inflammation or a benign crime.
On the other hand, the needles can control simply repeating the explorations, but can be anxious for the patients to pass months after the next test, knowing that they have something in their pulse that can be malignant.
Positive cases of false positives, when confounding something offensive with a cancer, are oscillating between 3.9 and 25 per cent and more in the studies, per tienden to decrease with time, while the patient is increasing to more annual explorations.
One of the main preoccupations of the false positives is that you can lie to invasive procedures, such as pulmonary biopsies. A large number of studies have been conducted that involve invasive procedures in the form of incontinence in the 1.7 per cent of patients who are tested for detection. The working group informs that the standards set by the radiology companies to evaluate the explorations will help to avoid any inconvenient procedures provoked by the false positives.
Another possible result of the exam is the probability that the exposure accumulated and the radiation can cause cancer. Without embarrassment, the dose is low and it is considered that the risk is small, especially when compared with the risk of pulmonary cancer caused by tobacco.
In theory, the crib also tombién powder should lie in tests and invasive treatments for a cancer that has not progressed or been perjured to the patient. I do not know what frequency I can handle this, but it is considered rare.
