In about one-forth of the people who develop lung cancer, no symptoms are noticed. Only when chest x-ray is done on the individual, one would know that the cancer is present or not. In rest of the people, lung cancer symptoms are apparent. The symptoms of lung cancer develop from the primary tumor and even from the metastatic tumor. Disturbances in the hormone levels are one primary reason why people develop the symptoms. Blood and the other systems start to take toll of the changes occurring due to cancer.

Lung Cancer Symptom In Case of Primary Tumor

The most common lung cancer symptoms in case of primary tumor are cough. People report of pain in the chest, shortness of breath as well as blood coming out in cough. If the cough that has developed is new and it is refusing to go away in spite of treatments then it is better to get yourself evaluated by a proper health care provider. Shortness of breath usually occurs because the flow of air is blocked. Sometimes fluid is deposited because of tumor too, which cause the breathing problems. If while you breathe, you notice any hoarseness or wheezing then it is a sign of an inflammation in the lung. It may be an infection but one must get them checked thoroughly. In fact, it is also seen that pneumonia, bronchitis and respiratory infections are common for lung cancer.

Lung Cancer Symptom In Case of Metastatic Tumor

Lung cancer signs and symptoms in case of metastatic tumors depend somewhat on the size of the tumor as well as on its location. When such type of tumor develops, there are chances that it might spread to the bones, adrenal glands and the liver or brain. If metastatis occurs towards the bone then back problems occur. One might also experience pain in their vertebrae, ribs, etc.
