The Spread of Lung Cancer

The Spread of Lung Cancer

The spread of lung cancer is to be given more importance due to its medical complications. It may be defined as a cancer that occurs in other sites of body like kidney, bladder, lymph nodes, etc., which subsequently spread via the blood stream or lymphatic system and into the pulmonary tissues like alveoli and interstitial tissues of the respiratory structures, therefore the process of metastasis finally sets in the lung areas. If the primary tumor is removed elsewhere in the body successfully, by routine anti-cancer treatment approaches, and at the same time if the tumor cells have spread only to a limited extent in the pulmonary regions, then the management of this condition by surgical technique may be of help. However, if there is an extensive metastatic lung cancer, then this clinical condition may not be cured fully.

Treatment procedures may not yield an expected result, despite various types of treatment procedures in patients, when a tumor reveals different stages of metastases. Therefore, the specialist always has to consider a poor prognosis, whenever metastatic cancer in lungs is encountered in an extensive form, over the various lobes of lungs in thoracic cavity.

Breast cancer can metastasize to other tissues like heart and other thoracic organs including the lung tissues. Similarly, cancerous cells may spread from colon to lungs, thus causing metastasis in different pulmonary areas. It is to be emphasized that currently, incidence of colon cancer is found to be more due to the multiple etiological factors like usage of various kinds of fertilizers, pesticides, etc. Hence, this cancer is to be viewed from various clinical angles.

Because of the spread of cancer cells, the clinical signs may vary depending on the degree of lung involvement and the reactions of the pulmonary areas to the modifications in cellular patterns. Whenever dealing with the case of this cancer in lungs the respiratory system specialist perhaps attempts to rule out signs and symptoms related to both primary and secondary lung cancers.

Metastatic lung cancer is often thought, by a substantial number of oncologists, that clinical recovery may not be 100 percent possible. The abnormal involvement of cellular structures of pulmonary regions get involved either primarily or secondarily. This is due to over exposure to cancer causing elements. Though it may not be practical to maintain moderate or no exposure 100 percent of the time, one can sustain from smoking or eating of known carcinogenic substances in food. Further, a constant environment in areas with asbestos or cement industries may become as predisposing factors for the occurrence of pulmonary infection, and in the course of time, this may end up in the occurrence of severe lung cancer and finally there is setting in process of metastasis in the affected patients.

Metastatic lung cancer often assumes more clinical significance because of the pronounced clinical signs like shortness of breath, difficulties in breathing, and coughing with some blood material in the coughed materials along with sputum. The lung tumor also can metastasize to other regions including kidney due to the spread of lung cancer.
