According to statistics, it has been found that lung cancer occupies the highest position among the causes of cancer death, regardless of sex. This is the reason why it is important to know the early symptoms of lung cancer. It usually develops between the ages of 45-70. Unfortunately, more and more women are falling victim to him, as an increasing number of them have started smoking. When lung cells become malignant, the condition known as primary lung cancer appears, but it can also be caused due to the spread of cancer from other areas of the body, which is known as metastatic cancer. Cancer commonly spreads to the lungs, bones, testicles, rectum, cervix, stomach, thyroid, kidney, prostate, colon and breast.
The first signals help in detecting the presence of cancer cells in the lungs. If you neglect the first signs of this cancer, you will miss a golden opportunity to cut off the cancer.
What are the early symptoms of lung cancer?
It can often be difficult to diagnose this disease on time, because the first symptoms are usually subtle, and when they occur more severely, it is already too late because by then the disease has usually progressed to advanced stages.
In fact, it has been observed that in a quarter of the cases in which lung cancer has been diagnosed there have been no symptoms of any kind, and that it was generally identified due to an X-ray of the chest taken by some other reason. The rest of the people experience early symptoms, some of which are often ignored, such as the symptoms of the common cold or flu. Following are the symptoms of early lung cancer:
- Persistent cough that gets worse over time
- Expectoration with blood, known as hemoptysis
- Chest pain
- Difficulty breathing
- Constant feeling of fatigue
- Involuntary weight loss
- Loss of appetite
- Swelling of the neck and face
- Persistent problems such as pneumonia and bronchitis
Some of the other symptoms include:
- Difficulty to swallow
- Abnormalities of the fingers or nails, such as overgrowth of tissues in the fingertips
- Pale skin or bluish color
- Atrophy or muscle contraction
- Joint swelling or pain
- Sensitivity or pain in the bones
- Eyelid Drop
- Breast development in men
Various types of lung cancer
More than 90 percent of primary cancers begin in the bronchi, in either of the two main branches of the trachea. This is known as bronchogenic carcinoma , with specific types of oat cells or small cell carcinoma , adenocarcinoma , large cell carcinoma , squamous cell carcinoma . Among them, the last three types are usually called non-small cell lung cancer.
A subtype of adenocarcinoma, known as alveolar cell carcinoma, has its origins in the alveoli, the tiny air sacs in the lungs. Although it can develop in one part of the lung, it often occurs simultaneously in several parts.
Some of the lung tumors that are not so common are the following: bronchial carcinoid that can be malignant or non-malignant; sarcoma, which is cancerous, and chondromatous hamartoma , which is non-malignant. Lymphoma is a type of cancer that affects the lymphatic system, which can have its origins in the lungs or spread to them.
One of the main causes is smoking. The longer the duration and the amount of tobacco use, the greater the chances of developing cancer. In fact, it has been observed that approximately 10-20 percent of all smokers end up developing cancer. Although non-smokers also suffer from lung cancer, smokers are much more susceptible.
Once a person quits smoking, it takes about 15 years for their chances of developing lung cancer to be equivalent to those of a non-smoker.
A few cases of lung cancers are caused by inhaled substances found in the workplace. For example, work with radiation, asbestos, chromates, arsenic, chloromethyl ethers, nickel, mustard gas and coke oven emissions have been linked to some cases. The chances of developing lung cancer are much higher in people who smoke and are also exposed to the substances mentioned above. Sometimes certain types, especially alveolar cell carcinoma and adenocarcinoma, occur in people whose lungs have been affected by other diseases of the lungs, such as fibrosis and tuberculosis. Exposure to radon gas at home can also cause lung cancer, although this is seen in less than one percent of cases.
Bosses are the three symptoms that should not be forgotten: persistent cough , especially when accompanied by blood-stained sputum; chest pain , especially when you cough or breathe; and shortness of breath . When these early symptoms of lung cancer arise, it is advisable to consult your doctor immediately, especially if you are over 40 years of age and smoke. Early detection will help control the spread of cancer. This will certainly help to improve the life of patients in general, as well as the quality of life after cancer.
