Lung Cancer Symptoms

Many symptoms of lung cancer are non-specific, leading to further delays in diagnoses.

Since there is no widely recognized method of early lung cancer detection, unlike PSA for prostate cancer or mammography for breast cancer, 85% of lung cancer is found symptomatically.

Unfortunately, by the time symptoms are apparent and properly diagnosed, the lung cancer tends to be in an advanced stage—that is one of the reasons why the 5 year survival rate is only 15%, with nearly half of newly diagnosed patients not surviving thefirst year.

Here are some common lung cancer symptoms:

Coughing Up Blood

Coughing up blood is an important symptom of lung cancer, but it is difficult to distinguish coughing up blood associated with lung cancer from coughing up blood associated with chronic lung conditions like COPD that has resulted from smoking. However, if you or a loved one are coughing up blood, you should see your physician immediately, as it could be a sign of a more serious condition. If a patient who had chronic cough, shows changes in the pattern of cough of starts coughing up blood, the possibility of lung cancer should be considered.

85% of lung cancer is found symptomatically, which includes various types of cough, including productive cough, coughing up phlegm, coughing up blood as well as other types. 

The America Cancer Society says that the early detection of cancer is your best defense. Therefore, finding lung cancer before these symptoms appear can be important in extending the survival rate.
