Lung cancer is also called lung cancer. It is a malignant lung tumor characterized by uncontrolled cell growth in lung tissue. This growth can spread beyond the lungs by the process of metastasis in nearby tissues or other parts of the body. The vast majority of lung cancer cases are due to long-term smoking. About 10 to 15% of cases occur in people who have never smoked. Most lung cancers cause no symptoms until they have spread. Noticing pain in these parts of the body can mean that you are at risk.
For someone worried about developing lung cancer, it is essential to consult your GP at the first symptom.
If the cancer is diagnosed at an early stage, the treatment is then more likely to be effective.
A common symptom of lung cancer is the sensation of pain in the chest, back, or shoulders when breathing.
These pains can also occur when you laugh or cough. As the cancer develops, the pain in the chest, back, or shoulders becomes more severe or intense.
Other symptoms to watch for include new coughs. Experiencing a new persistent or aggravated cough, a change in an existing chronic cough or a cough that produces blood are early warning signs of lung cancer.
The American Cancer Society said: "The most common symptoms of lung cancer are hoarseness, weight loss and loss of appetite, shortness of breath, feeling tired or weak, infections such as bronchitis and pneumonia that do not go away or wheeze.
"If lung cancer spreads to distant organs, it can cause bone pain, changes to the nervous system, yellowing of the skin and bumps on the surface of the body due to cancer spreading to the skin or to the skin. lymph nodes. "
Less common lung cancer symptoms include swelling of the face or neck, difficulty swallowing or pain while swallowing, and changes in the appearance of the fingers, also known as bludgeoning fingers.
The NHS said: "Lung cancer mainly affects the elderly. It is rare in people under 40 and lung cancer rates increase sharply with age.
Lung cancer is most commonly diagnosed in people aged 70 to 74 years.
Although people who have never smoked can develop lung cancer, smoking is the main cause, accounting for more than 85% of cases.
Indeed, smoking involves the regular inhalation of a number of different toxic substances. "
If you suspect lung cancer or if you know someone who suffers from it, it is important to talk to your doctor.
