Diagnosing lung cancer early, before it has developed or spread, is often difficult, as symptoms usually appear as the condition progresses.

It is known that the most common cause of lung cancer is smoking, as more than 70% of all cases are related to smoking. For non-smokers, second-hand smoke in the home or workplace may increase the risk of lung cancer by up to 30%. The most common form of lung cancer forms in the air passages leading to the lungs. If the tumor blocks the airways, it can cause shortness of breath, wheezing and a persistent cough that may include blood and phlegm.

A tumor in the upper part of the lung may press on nerves and blood vessels entering the arm, causing pain and weakness in the limb. This may be accompanied by a permanent feeling of tingling.

An early sign of the disease, which is difficult to detect, is clubbing, where the tips of the fingers become engorged due to a lack of oxygen.

In some cases, the tumor may compress blood flow to the head, causing swelling around the face.

Common signs with other forms of cancer include fatigue and weight loss.

In some cases, a lung tumor may release large amounts of hormones that cause distant symptoms in the body.

Lung cancer can overlap with other lung infections. If someone has a lung infection that doesn’t respond to antibiotics or other treatments, that may prompt a doctor to look for lung cancer with a chest X-ray.

A warning sign of serious cancer

This initial test can identify abnormal structures in the lung that suggest cancer, but more testing is often required afterward to confirm a positive diagnosis.

A CT scan produces a 3-D image of the lungs, while a biopsy of the lymph nodes can determine whether the cancer has spread outside the lungs.

The result of the additional tests often determines the treatment options a doctor can offer. It is noteworthy that the more advanced forms of lung cancer are difficult to treat, but treatment can still slow the progression of the disease and relieve the most painful symptoms.

Lung cancers often spread more quickly than other forms of cancer, as cancer cells spread through the blood that passes through the lungs and travel to the rest of the body. This is why lung cancer is often detected after it has spread.

You can reduce your risk of lung cancer by maintaining general physical health and avoiding risk factors, such as smoking, air pollution, and some chemicals that can cause cancer when inhaled or handled.
