The occurrence of lung cancer is associated with smoking, air pollution, and working in environments such as coal mining. However, lung cancer is not contagious. Therefore, in clinical settings, family members of patients often ask doctors whether lung cancer can be transmitted through the respiratory tract. It can be assured that lung cancer is not contagious; only communicable diseases like tuberculosis can be spread this way.

Will people with lung cancer experience weight loss?

This question should be answered specifically. Some people may initially experience symptoms such as weight loss and fatigue when they start to develop lung cancer. Some people with better physical constitution may not lose weight so easily. However, if a malignant tumor persists in the body for a long time, it will consume the body's nutrients and lead to a state of cachexia, characterized by systemic toxicity symptoms including weight loss, fatigue, fever, and other similar symptoms.

Early symptoms of lung cancer

Early-stage lung cancer, especially peripheral lung cancer, often has no symptoms and is mostly found during chest X-rays or CT scans. The clinical symptoms of lung cancer are closely related to the location, size, pathological type of the tumor, whether it compresses or invades adjacent organs, and whether there is metastasis. The symptoms of lung cancer generally include: First, some symptoms of the primary tumor growing locally, including cough, hemoptysis, difficulty breathing, and chest pain. When the tumor grows inside a larger bronchus, it might cause some irritative coughing. Second, as the tumor continues to grow and affects the drainage of the bronchi, it may lead to secondary lung infections, presenting with symptoms such as cough and purulent sputum. Third, there might be bloody sputum streaked with blood or intermittent minor hemoptysis, though significant hemoptysis is very rare.

Does shoulder pain mean lung cancer?

The most common cause of shoulder pain is chronic strain of the ligaments and muscles in the shoulder, not lung cancer. Lung cancer accounts for only a small portion of the reasons. If a patient has lung cancer, it can spread to the shoulder, or the lung cancer itself can produce a type of referred pain, which can cause shoulder pain. To determine the cause, it is necessary to go to the hospital for an X-ray of the shoulder joint or a plain chest film, as well as an MRI of the shoulder joint, to clarify the cause of the shoulder pain. If the pain is solely due to the muscles or ligaments in the shoulder, it can be relieved through conservative treatments such as massage, acupuncture, electrotherapy, and magnetotherapy.

What are the symptoms of lung cancer?

The most common symptoms of lung cancer include coughing, particularly irritating coughs, and symptoms of coughing up blood. The blood in the sputum may appear as spots, streaks, or intermittent small amounts. Other symptoms include difficulty breathing and chest pain, as well as potential tightness in the chest, shortness of breath, and fever. Secondly, if lung cancer grows within the thoracic cavity and spreads, invading nearby tissues and organs, it can produce secondary symptoms. For example, paralysis of the phrenic nerve on the same side may lead to difficulty breathing and belching. Compression of the recurrent laryngeal nerve may cause hoarseness; compression of the superior vena cava can lead to distended veins in the face, neck, and upper limbs; subcutaneous edema; and if the pleura is invaded, it can cause pleural effusion, among other symptoms. If lung cancer metastasizes through the bloodstream, it may spread to the brain and potentially lead to symptoms such as headaches, nausea, and vomiting. Metastasis to different regions of the brain might cause various symptoms, including seizures, mental confusion, and vision impairment. In a minority of cases, lung cancer may produce endocrine substances, possibly leading to symptoms like severe muscle weakness, bone and joint pain, and other such symptoms.
