Cancer is an extremely dangerous disease, and lung cancer is one of the most common and dangerous types, and what makes it dangerous is that it does not usually cause noticeable symptoms until it spreads through the lungs or other parts of the body, and survival rates vary widely, depending on the extent of cancer. At the time of diagnosis, it is therefore necessary to pay attention to some symptoms that could be indications of disease.
A cough that lasts for a period of two to 3 weeks is one of the main symptoms of lung cancer, and if the cough does not disappear after this period, it can be an indication of lung cancer, according to “24”.
Other main symptoms include:
A long-lasting cough that gets worse over time
Infections in the chest come back frequently
Coughing up blood
Pain when breathing or coughing
Persistent shortness of breath
Constant fatigue or lack of energy
Loss of appetite or unexplained weight loss
Causes of lung cancer
Most lung cancer cases are caused by smoking, although people who have never smoked can develop this condition as well, and according to the Cancer Research UK, about seven out of 10 lung cancer cases are caused by smoking, and this includes inhaling cigarette smoke. Others.
One study showed that the risk of lung cancer increases by about 33% if you live in an area that has high levels of nitrogen oxide gases, often produced by cars and other vehicles.
Some substances can also increase the risk of lung cancer, including asbestos, silica and cadmium, and genetic makeup may also determine your risk of lung cancer.
The most common treatment options include: surgery, radiotherapy, chemotherapy and immunotherapy, depending on the type of cancer and the stage it has reached, and the patient can receive a combination of these treatments at the same time, according to the British newspaper Express.
