Many women worry about getting breast or ovarian malignancy. But did you know that lung cancer kills much more American people than other cancers do?
In the past 25 years, lung cancer has distilled breast cancer, becoming No.1 in the causes of cancer deaths.
Cancer develops when body cells undergo certain transformations and begin to grow and propagate without any control.
Malignant tumors take nutritive elements, space and oxygen from normal cells, destroy them and affect normal functioning of the organs.
Lung tumors are commonly malignant and can spread to any other body region. It’s also a big problem that lungs contain wide net of vessels and lymphatic tubes, which can act as pathways for cancerous cells.
There are two general kinds of lung cancer. Small cell lung malignancy is a less common type, which usually appears in heavy smokers.
Most lung cancers are non-small cell lung neoplasms that involve adenocarcinoma, squamous cell carcinoma and large cell carcinoma.
Smoking is a well known and the most significant risk factor for lung cancer. Cigarette smoke contains more than 4000 harmful substances, which can damage lung cells and trigger their transformation.
The more cigarettes you smoke, the higher chances of this disorder you have. Number of years you’re exposed to tobacco smoke plays a role too. Even secondhand smoking was found to boost risks of experiencing lung cancer.
Having family history of this dangerous condition and being exposed to arsenic, asbestos or other carcinogens can also increase your chances of getting lung neoplasm.
It’s not uncommon that lung cancer stays symptomless for a long time, until it spreads to distant areas. But sometimes it’s possible to catch this trouble on the early stage. Remember that early detection helps to treat cancer in the most effective way.
Check up these signs and symptoms of lung cancer:
#1. Persistent cough – cough is commonly associated with respiratory infection. But be aware that if it doesn’t go away after few weeks, it may be a sign of lung cancer.
#2. Hemoptysis (coughing up blood) – even small amount of blood is a reason for concern about lung cancer.
#3. Discomfort in the chest – not only heart attack may be responsible for unpleasant sensations in the chest. Ongoing pain in the chest, shoulders or upper back that worsens when you cough and breathe deeply, often indicate serious problems in the lungs.
#4. Shortness of breath – breathlessness is often associated with heart problems. But sometimes changes in breathing may occur as a result of growing lung tumor.
#5. Wheezing – there is wide variety of factors, which may constrict your airways, causing wheezing. And lung cancer is among them too.
#6. Hoarseness – your voice may become deep and hoarse because of common cold. However it’s worth consulting with medical professional, if changes in the voice haven’t been improved in the course of two weeks.
#7. Reduced appetite and unintentional weight loss – sudden loss of body weight is not a thing to be happy about. It could be a sign of progressing cancer and spreading it throughout the body.
