Lung cancer
Can early-stage lung cancer cause shoulder pain?
In the early stages of lung cancer, it generally does not cause shoulder pain. Early-stage lung cancer often does not involve critical structures and typically does not produce noticeable clinical symptoms. However, a small number of central lung cancers may cause symptoms related to coughing. Moreover, shoulder pain can occur in cases of lung cancer, often seen in superior sulcus tumors. A superior sulcus tumor, also known as a Pancoast tumor, is a tumor located at the top of the lung. As the tumor grows, it may compress the brachial plexus nerves, leading to symptoms such as shoulder pain and throat pain. It can also cause symptoms like enophthalmos (sunken eyeball) and pupil constriction. Therefore, when encountering these signs clinically, it is necessary to consider the possibility of a superior sulcus tumor and conduct examinations like a chest CT scan for evaluation.
How is lung cancer detected?
For lung cancer detection, it is recommended for individuals over forty, especially smokers, to undergo a low-dose spiral CT for screening. Secondly, if someone has been a long-term heavy smoker and has undergone chest X-rays and low-dose spiral CT and a lung mass is found, it is suggested that the patient undergo a contrast-enhanced CT or a PET-CT to determine the condition and location of the lung mass. After establishing the condition and location, a sputum cytology test can be conducted. Thirdly, to confirm whether it is lung cancer, one should undergo bronchoscopy to obtain a biopsy, or a transthoracic lung puncture biopsy, or examine live tissue or metastatic lesions, or perform a pleural fluid examination to detect the cancer cells and determine the specific type of lung cancer to guide treatment. However, if the nature of the lesion cannot be clearly determined through mediastinoscopy, bronchoscopy, chest wall puncture biopsy, or other methods, a thoracotomy exploration is recommended. Additionally, the examination of tumor markers cannot be ignored.
Is coughing up blood lung cancer?
Patients with lung cancer can experience hemoptysis, but the occurrence of hemoptysis does not necessarily mean that it is caused by lung cancer. Although hemoptysis is a symptom of lung cancer, there are many other diseases that can cause it as well, such as tuberculosis, bronchiectasis, lung abscess, various pneumonias, certain heart diseases, blood disorders, etc. Therefore, it can only be said that hemoptysis may be an indication of lung cancer, not that hemoptysis confirms the presence of lung cancer.
Symptoms of malignant transformation of chronic obstructive pulmonary disease
Firstly, cancer transformation is not the main complication of chronic obstructive pulmonary disease (COPD), but both COPD and lung cancer share a common cause, which is smoking. Therefore, COPD and lung cancer are generally considered two different diseases, and the symptoms of COPD combined with lung cancer are mainly those of lung cancer, typically including irritating dry cough, blood-streaked sputum, weight loss, etc. Thus, lung imaging studies can be used to preliminarily determine the possibility of cancer in patients, and further diagnostic steps can be chosen based on the patient’s imaging and related symptoms, including biopsy, bronchoscopy, etc.
What should I do about dry cough and wheezing caused by lung cancer?
Patients with lung cancer presenting with dry cough and wheezing often require treatment to suppress coughing, alleviate wheezing, and address the symptoms. It is also important to check if the patient has concurrent obstructive pneumonia. Lung cancer combined with obstructive pneumonia can also lead to dry cough and wheezing. In such cases, anti-infection treatment is needed, along with treatment specifically targeting lung cancer itself. Dry cough and wheezing in lung cancer often suggest that the cancer may be in the middle to late stages, where the chances of surgery are generally small. However, it is still necessary to complete relevant examinations to further assess the condition. If the patient is eligible for surgery, surgical treatment should be considered. If the patient is indeed in the middle to late stages of lung cancer and is not suitable for surgery, chemotherapeutic drugs are needed for treatment. Sometimes, targeted drugs can be chosen for treating advanced-stage non-small cell lung cancer. In cases of advanced non-small cell lung cancer with driver gene mutations, targeted therapy might even be the preferred treatment option.
Is hemoptysis lung cancer?
Coughing up blood is not necessarily lung cancer. Among respiratory diseases, the three most common causes of coughing up blood are, first, bronchiectasis; second, pneumonia and lung abscess; and third, lung cancer. So how can we determine the cause? The best, simplest, and fastest method is to go to the hospital for a lung CT scan as soon as coughing up blood occurs. If the lung CT shows bronchiectasis, then bronchiectasis should be considered; if it shows an infiltrative lesion, then pneumonia should be considered; if it shows a tumor, then lung cancer should be considered at that time. However, there is also a scenario where blood is coughed up, but the lung CT is completely normal. What should be done then? This situation might be due to pharyngitis. Sometimes, severe coughing from pharyngitis can cause bleeding of the mucous membranes in the throat. In this case, there’s no need for excessive worry, as it may be caused by factors involving the throat. Cough gently, and if there’s no blood when coughing lightly, it’s likely not serious. However, if there's still blood in the sputum even when coughing lightly, it is recommended to undergo a bronchoscopy to check for tuberculosis or cancer in the bronchi.
Small cell lung cancer and non-small cell lung cancer differences
Small cell lung cancer and non-small cell lung cancer are both types of primary bronchogenic carcinoma, differing only in their cellular morphology. They also differ in clinical symptoms and characteristics of metastasis. Small cell lung cancer is more prone to metastasis clinically, including strenuous and distant spread, such as to the brain and liver. The medications used for each are also different; small cell lung cancer typically involves chemotherapy drugs like etoposide and cisplatin, whereas non-small cell lung cancer commonly uses drugs like paclitaxel and platinum-based drugs.
What foods should not be eaten with lung cancer?
Lung cancer patients definitely should not smoke. Many lung cancer cases are caused by smoking, and if a patient quits smoking after the onset of the disease, their prognosis is much better compared to those who continue smoking. Additionally, there is advice to avoid certain so-called trigger foods. For cancer patients, the recommended meats are fish and poultry. This recommendation is not really due to the issue of trigger foods but because fish and poultry are easier to digest and absorb. During cancer treatment, the tumor itself causes a significant breakdown of proteins in the body. Since proteins are a fundamental basis for bodily functions, without them, human survival would be nearly impossible. Therefore, it is essential to replenish proteins. The main sources of protein include meat, eggs, dairy products, soy products, and nuts, which are all crucial sources of protein.
Symptoms of lung cancer transformation in chronic obstructive pulmonary disease
Lung cancer is a complication of chronic obstructive pulmonary disease (COPD), but it is relatively less common for COPD patients to also have lung cancer. Regular health check-ups, including annual lung CT scans, can help identify the possibility of cancerous changes at an early stage. In the early stages of lung cancer, patients generally do not show obvious clinical symptoms. As the disease progresses, symptoms such as coughing up blood, weight loss, fatigue, and night sweats may occur. However, since the clinical symptoms of lung cancer are similar to other lung diseases, there are no typical clinical features, and imaging studies are needed for preliminary screening.
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.
