Lung cancer is one of the most common cancers in the world . Statistics show that each year the world records more than 2.2 million new cases of lung cancer, according to the health website Medical News Today (UK).
Healthy cells in the body divide and make many different copies, and this is a normal function. However, in cancer patients, cells are damaged for some reason, mutate and divide uncontrollably. Over time, they form cancerous tumors that prevent organs from functioning normally.
Smokers are at significantly higher risk of developing lung cancer than non-smokers. In many parts of the world, more men smoke than women. As a result, lung cancer occurs more frequently in men.
Early warning symptoms of lung cancer in men include:
Persistent cough
Smokers who have persistent cough, chest pain and unexplained weight loss should be screened for lung cancer as soon as possible.
Coughing due to a cold or respiratory infection is normal. But if the cough lasts more than a week and is accompanied by other symptoms, it could be lung cancer.
These signs include increased coughing, increasingly severe coughing, and a hoarse sound. In addition, while coughing, the patient also coughs up blood and a lot of mucus.
Shortness of breath or wheezing
Shortness of breath or wheezing is also one of the common symptoms of lung cancer. In cases where the tumor blocks or narrows the airway, the patient also experiences irregular breathing.
Body aches
If you lose 4.5 kg or more without a clear cause, you should see a doctor as soon as possible.
Lung cancer causes pain in the chest, shoulders, or back. This pain is very common, even throughout the day. The pain can be sharp or dull, constant or intermittent.
In advanced cases of lung cancer, the patient not only feels pain but also feels very uncomfortable in the chest. The cause is due to swollen lymph nodes and metastasis to the chest wall. Lung cancer cells metastasize to which location will cause pain there.
Weight loss
Any serious illness, including lung cancer, can cause significant weight loss. If you lose 10 pounds or more without a clear cause, you should see a doctor as soon as possible, especially if you smoke or have had cancer, according to Medical News Today.
