Early symptoms of adenocarcinoma?

summary

Lung cancer is one of the high incidence of respiratory tract tumors. The early symptoms of lung cancer are similar to common respiratory diseases, so many patients are easy to ignore in the early stage of lung cancer. When they are found to have lung cancer, it is often in the middle and late stage. At this time, the treatment effect is not good, and the prognosis is not optimistic. Early symptoms of adenocarcinoma? Next, I'd like to share my views with you.

Early symptoms of adenocarcinoma?

Early extrapulmonary manifestations of bone and joint symptoms: such symptoms are more common. Lung cancer cells can produce some special endocrine hormones (heterologous hormones), antigens and enzymes. These substances act on bone and joint parts, causing swelling and pain of bone and joint, often involving tibia, fibula, ulna, radius and other bones and joints,

Shoulder and back pain: peripheral lung cancer often develops backward and upward, eroding pleura, involving ribs and chest wall tissue, causing shoulder and back pain. These patients rarely have respiratory symptoms. Hoarseness: lung cancer metastasis compression laryngeal nerve, can make vocal cord single board machine arthralgia and hoarseness. Because the metastatic foci of lung cancer can appear in the early stage, and sometimes the metastatic foci can grow faster than the primary foci, the clinical manifestations of the metastatic foci can appear earlier than the primary foci.

The late symptoms will be different due to the different constitution of the patients. The condition of lung cancer is more serious in the late stage, which needs timely symptomatic treatment. Pain is a common symptom in patients with advanced lung cancer. Most patients with lung cancer who have regional intrathoracic dissemination have symptoms of chest pain.

matters needing attention

Prohibition and control of smoking: the mechanism of lung cancer caused by smoking has been clearly studied. Epidemiological data and a large number of animal experiments have fully proved that smoking is the main factor of lung cancer. The state should make strong laws to publicize that tobacco contains carcinogens that cause lung cancer.
