Lung cancer symptoms you should be aware ofWhy is it important to know about lung cancer symptoms?
Lung cancer is one of the most dangerous types of cancer because it
tends to spread to body organs at an early stage. For this reason,
being aware of common lung cancer symptoms is essential - early
detection significantly improves chances of survival.
Tumors that are benign usually do not pose a threat and
can be removed
without spreading to other parts of the body. Malignant tumors, like
those of lung cancer, multiply and spread aggressively. They tend to
move to other - often distant - parts of the body, in a process called
metastasis.
However, if some of these signs are present, it is necessary to consult a doctor so that he can investigate further. When the disease spreads to other parts of the body, it can give rise to other lung cancer symptoms. Examples include bones that fracture too easily, persistent / recurrent headaches, formation of blood clots, bleeding, pain in some area of the body, etc. Some symptoms may not be apparent till the disease has progressed to become stage 4 lung cancer. Early detection is critically important to improve the chances of curing lung cancer. In patients where the cancer has already advanced, detection can still help to prolong life and improve its quality. Lung cancer symptoms can be caused by various factors. Smoking heads the list of causes. An estimated nine out of ten cases of lung cancer would never have developed if the patient did not smoke. That is a shocking statistic. Asbestos exposure is another known risk factor. Researchers have found that asbestos workers are fully seven times more likely to develop lung cancer as compared to the general population. Other risk factors include exposure to toxic chemicals, heavily polluted air in big cities, lung inflammation, etc. Having a family history of lung cancer also increases the risk of a person developing the disease. Lung cancer symptoms - gender differencesIn many diseases, the symptoms that men exhibit may be somewhat different from those shown by women. This may be the case with heart diseases, for example.However with lung cancer, most of the time, it gets detected only at a highly advanced stage, after it has spread to other areas of the body. This is especially true of small cell lung carcinoma, although such metastasis can also occur in non-small cell lung carcinoma. By that time, both men and women tend to show very similar symptoms. For instance, loss of weight, unexplained pain in the chest or some other part of the body, loss of appetite and so on. Thus in practical terms, there aren't major differences between men and women when it comes to signs of lung cancer. The presence of any of these lung cancer symptoms is sufficient reason to consult a doctor as soon as possible. Also read: Is lung cancer genetic?
