Early signs of lung cancer
Patients should be carefully examined clinically, for patients with known or suspected lung cancer because of the diverse manifestations of local progression - regional and distant metastases.
Cancer in the lung parenchyma does not cause pain, so it is often when the disease is advanced that symptoms appear. Symptoms present at the time of diagnosis of lung cancer depend on the location and size of the tumor, any metastases as well as the extent of invasion to the organs, and the random appearance of the findings. pre-cancer.
Cough a lot
Common symptoms are cough, accounting for about 70% of cases, shortness of breath, hemoptysis, recurrent pneumonia, chest pain. May be accompanied by hoarseness, due to direct tumor invasion or mediastinal lymph node metastasis and vocal cord paralysis.
Pain in hands, shoulders and fingers
When the tumor is at the apex of the lung, invasion of the chest wall and brachial network causes arm and shoulder pain with paresthesia. This group of symptoms is called Pancoast syndrome. When the cancer at the top of the lung has spread and invaded the sympathetic nervous system, Horner's syndrome appears with symptoms of drooping of the eyelids on the same side of the lesion (droopy eyelids), constricted pupils, sunken eyes (eyes retracted inwards). orbit) and no perspiration on the side of the face on the same side of the lesion.
Weight loss
In any case, rapid weight loss with no apparent cause, unrelated to the fact that you have cut calories or exercise... is most likely caused by illness, including cancer. In addition, if you feel that your appetite is not good, it is easier to conclude that the cause may be a tumor inside your body, not except a tumor in the lungs, leading to lung cancer later. This tumor will be the sudden increase in metabolism in your body and cause the above condition.
Frequent infections
Lung cancer can cause infections that affect the airways and lead to illnesses like bronchitis or other chronic infections. If you have a chronic lung infection, it's a good idea to take the time to get a chest X-ray to see if you're at risk for lung cancer.
Abnormalities in breast tissues
This sign is more common in men. It is an abnormally enlarged breast caused by abnormally stimulated hormone secretion by cancer cells. However, women should not ignore this, because it is most likely caused by lung cancer cells or cancer in other parts.
Precancerous signs
Prominent precancerous signs are seen in about 10% of lung cancer patients. The patient's general condition deteriorated due to tumor necrosis factor. Pulmonary hypertrophic osteoarthropathy is probably due to chronic hypoxia, manifested by clubbing. Clubbing includes an increase in both the width of the fingernails and the convex surface of the finger in profile. Other syndromes include coagulopathy, skin, neurological, endocrine, renal, and muscular manifestations.
