Considering the evolution of “silent” disease, is important in performing pelvic examinations regularly. A way of highlighting the viral lesions is colposcopy, the gynecologist will be recommended when you have some changes. It is advisable to be done annually, along with routine gynecological control.
Duration of infection in clinical manifestations is between 1 – 8 months, but it is possible that the infection will remain dormant years.
Risk factors The main risk factor is smoking. According to statistics, 90% of people diagnosed with lung cancer are or were smokers.
There are other factors that contribute to disease:
- An environmental exposure: asbestos, radon, arsenic;
- Exhaust gas;
- Petroleum products;
- Synthetic fibers.
Unfortunately, signs and symptoms, first symptoms to pass very long time and they are usually mistaken for a cold or bronchitis. Signs and symptoms include:
- Chronic cough ;
- Constant chest pain ;
- Bloody sputum color ;
- Shortness of breath and hoarseness ;
- Repeated lung infections such as pneumonia or bronchitis ;
- Loss of appetite and hence weight loss;
- Unexplained anemia (Anemia is a condition in which people have fewer than the expected number of red blood cells in their blood. Anemia should be investigated).
It can happen that these symptoms may not appear, but other signs to worry about, such as metastatic spread to other organs. One of the most important differences between small cell lung cancer and lung cancer non-small cell is fast growing and spreading of cancer cells. As in SCLC tumor grows and spreads more quickly than in NSCLC.
Diagnosis – To diagnose a series of tests are performed such as:
- Chest radiography – is the simplest method that raises the suspicion of lung cancer;
- Sputum analysis – can detect an existing infection in blood or sputum;
- Blood tests – are to check the overall health and may indicate the presence of cancer in other organs;
- Bronchoscopy – requires fair view of the bronchial tree and harvesting tissue for biopsy;
- Biopsy – take a small portion of the diseased tissue is examined under a microscope to determine the final diagnosis;
- CT scan – shows a picture of body organs and senses three-dimensional appearance of metastases in other areas;
- MRI (magnetic resonance) – is similar to CT, but shows a different image through a magnetic field;
- PET radiography – offers images of malignant tumors throughout the body.
