Everyone knows that lung cancer can cause coughing up blood, but does coughing up blood necessarily mean one has lung cancer? It should not be interpreted this way. Although lung cancer can cause coughing up blood, there are many reasons for coughing up blood, and it is not only caused by lung cancer. Reasons for coughing up blood can also include bronchitis, pneumonia, bronchiectasis, tuberculosis, lung abscess, and many others. Therefore, if coughing up blood occurs, it doesn't necessarily mean one has lung cancer, and there is no need for excessive worry. If coughing up blood occurs, it is important to visit a hospital in a timely manner, where a doctor can conduct checks like chest X-rays to further investigate the cause.

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.

How is lung cancer treated?

For the treatment of lung cancer, it should currently be based on a comprehensive treatment method tailored to the patient's age, specific condition, nutritional status, economic condition, and the capabilities available at the hospital. It is particularly related to the stage of the disease and the type identified in the tissue biopsy. Currently, lung cancer primarily adopts a multidisciplinary comprehensive treatment approach spearheaded by surgical intervention. Surgical treatment is the preferred method for lung cancer, but since it is a systemic disease, surgery alone cannot completely address the issue. Therefore, it must be combined with radiotherapy, chemotherapy, and other treatments in a multidisciplinary and comprehensive approach. Additionally, immunotherapy and targeted therapy are inseparable and crucial parts of integrated treatment strategies for lung cancer. If the disease is staged and involves adenocarcinoma or squamous cell carcinoma of the lung, surgical treatment is recommended followed by adjuvant radiotherapy or chemotherapy, or targeted and immunotherapy. If surgery is not possible, some supportive treatments can be considered. For small-cell lung cancer, surgery is not recommended because it offers no benefit; instead, a combined approach of chemotherapy and radiotherapy is advised.

What is good to eat for lung cancer?

For dietary recommendations regarding lung cancer, the first suggestion is to maintain a regular diet and lifestyle with a routine schedule, focusing on easy-to-digest and absorbable foods. The second suggestion is to enhance nutrition intake, for instance, by consuming more eggs, milk, and other high animal protein foods, such as quality protein sources. The third suggestion is to eat more healthy green foods, such as vegetables and fruits, focusing on fresh items. The fourth point is to advise against smoking and drinking alcohol, and to consume fewer irritating foods.

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.

incidence of lung cancer

In recent years, the incidence of tumors has continued to rise, becoming a major killer threatening public health. According to global cancer statistics from 2015, in 2012, there were approximately 14 million new cases of cancer worldwide. Among these, lung cancer had an incidence of 1.8 million, accounting for 13% of all cancer cases. It is the type of cancer most frequently diagnosed and is also the leading cause of cancer death among men globally and women in developed countries. So, what is the current situation of lung cancer incidence in our country? The National Health Commission has stated that in 2014, there were about 3.804 million new cancer cases in China, with lung cancer having the highest incidence at 181,000 cases. Lung cancer presents complex clinical symptoms and its early symptoms are relatively mild, leading many patients to seek medical advice only in the late stages, thereby missing the optimal treatment window.
