Lung Cancer: Causes, Detection and Treatment
Cancer screening at an early stage, before it has had a chance to spread, is an incredibly high factor in a patient’s chances for survival. Although the symptoms of early cancer are hard to spot, early detection does lead to a greater number of treatment options, the possibility for less invasive surgery and generally higher survival rates. Recently, early diagnosis of cancer that was still localized meant a five-year survival rate of almost 50% of patients.
Unfortunately, though, no proven screening tests for lung cancer exist which significantly improves the chance of survival from or detection of the disease in a localized form. Nevertheless, methods to develop screening for the early detection of this cancer need to occur because symptoms at an early stage are so subtle, if apparent at all. Only in the late stages of this cancer do symptoms such as persistent coughing, chest pain, voice changes, and …
