The paratracheal lymph nodes are distributed in the neck along both sides of the trachea (trachea). When you get sick from a sore throat or a cold, these lymph nodes are usually swollen. Lymph nodes are an important part of the body's immune system. When they are painful or swollen, this may indicate a serious illness, including cancer.

The human body has a complex system of blood vessels and nodes that can move fluid called lymph to tissues in the body. The lymphatic system is the main contributor to the human immune system, acting as a filter for various foreign bodies.

Lymph fluid is composed of water, salt, plasma proteins and white blood cells. Lymph fluid from the intestines and liver is called chyle and contains more protein and fat. Lymph fluid brings various nutrients to tissue cells. When it passes through the lymph nodes, it filters out waste materials such as carbon dioxide and foreign objects such as bacteria, viruses and even cancer cells.

There are hundreds of lymph nodes around the body in clusters, but under normal circumstances, they are not easily felt. However, when there are diseases such as infection or cancer, the lymph nodes produce extra white blood cells, causing them to swell. Swollen lymph nodes are usually the first detectable sign of disease.

Although they are sometimes called glands, the functions of lymph nodes are slightly different. The glands usually secrete a fluid; for example, the lacrimal gland above the eyeball secretes tears, while the pituitary gland secretes hormones throughout the body.

But the lymph nodes do release substances that help the body fight infections. For example, when lymph nodes in the neck swell, it usually indicates that your body is struggling with a minor infection, such as an ear infection or strep throat.

Smoking is one of the main causes of neck and head cancer. If you smoke and drink at the same time, the incidence of this cancer will be higher. The most common type of tumor in the trachea is called squamous cell carcinoma. This is usually the result of smoking. This type of cancer is most common in men who are 50 to 70 years old who smoke.

If you are a smoker, remember that after smoking your last cigarette, your body will soon begin to heal and repair itself. Quitting smoking can reduce the risk of cancer, chronic obstructive pulmonary disease (COPD), heart disease, stroke, heart disease and many other health problems. In fact, one year after you quit smoking, your risk of heart attack will be significantly reduced. After two to five years, your risk of stroke is similar to that of a non-smoker. After 5 years of quitting smoking, your risk of esophageal cancer, oral cancer, throat cancer, and bladder cancer has been reduced by half, and 10 years later, your risk of lung cancer has been reduced by 50%. Discuss your smoking cessation options with your healthcare provider.
