What are the early symptoms of lung cancer? Several common manifestations of early lung cancer

Lung cancer is prone to distant metastasis in the early stage, so symptoms related to distant metastasis are often the early symptoms of lung cancer discovered by doctors or patients. If the lesion metastasizes to the brain, it may cause persistent headaches and blurred vision. Continuing development may lead to confusion and even epilepsy. The nature of this headache is not significantly different from ordinary tension headaches, so it is easy to be ignored.

In life, lung cancer is a common disease that brings great harm to the health of patients. I believe that everyone has seen many examples of death due to lung cancer in life. Once lung cancer occurs, everyone will definitely be very worried. In fact, the chances of curing lung cancer in the early stage are very high. For lung cancer, we must diagnose and treat it as early as possible. So what are the early symptoms of lung cancer?

Early symptoms of lung cancer

Some lung cancers will metastasize to distant sites at an early stage, so symptoms related to distant metastasis are often the early symptoms of lung cancer discovered by doctors or patients. If the lesions metastasize to the brain, persistent headaches and blurred vision may occur. Continuing development may lead to confusion or even epilepsy. The nature of this headache is not significantly different from ordinary tension headaches, so it is very easy to be ignored.

Among the early symptoms of lung cancer, blurred vision mainly manifests as difficulty reading newspapers or watching TV. Because most lung cancer patients are elderly, they often mistakenly believe that they only need to change their glasses, but the key lies in the change in the nature of vision. Initially, they are very sensitive to changes in consciousness and vision.

If cancer metastasizes to the bone, it will cause bone destruction. When the destruction reaches a certain level, bone pain will also occur. If the outer hard cortical bone is destroyed, the bone structure will be extremely unstable. If it occurs in the ribs, there may be discomfort, but if it occurs in long bones with heavy loads such as the femur or humerus, it is also very easy to fracture during daily activities. If this symptom appears in the early symptoms of lung cancer, you should go to the hospital for examination and treatment in time.

The metastasis of lung cancer to the spine is the most important early symptom of lung cancer. In most patients, spinal metastasis can cause pain. Cancer can further metastasize to the spinal cord, manifesting as back pain, and then spread to the lower limbs, which may cause lower limb weakness, incontinence, and eventually lead to paralysis below the metastasis point. Therefore, heavy smokers who experience back pain should also pay enough attention.

Can lung cancer be cured? I believe this is something that many patients are concerned about. In fact, the earlier lung cancer is treated, the greater the chance of cure. Early lung cancer is likely to be cured. Therefore, if lung cancer occurs, we must treat it in time and do not delay the disease. We must achieve early detection, early treatment, and early recovery.
