summary

Lung cancer is one of the most malignant tumors that incidence rate and mortality rate increase fastest and is the most dangerous to the health and life of the population. In recent 50 years, many countries reported that the incidence rate and mortality rate of lung cancer were significantly higher. Incidence rate and mortality rate of male lung cancer were the first in all malignant tumors. The symptoms of lung cancer were significantly different. Next, I'd like to share my views with you.

The symptoms of lung cancer are very significant

Cough is the most common symptom, with cough as the first symptom accounting for 35% - 75%. Cough caused by lung cancer may be related to changes in bronchial mucus secretion, obstructive pneumonia, pleural invasion, atelectasis and other chest complications,

When the tumor grows in the bronchial mucosa above the large diameter and sensitive to external stimulation, it can produce cough similar to that caused by foreign body like stimulation. The typical manifestation is paroxysmal irritative dry cough, which is often difficult to control by general antitussive drugs. When the tumor grew in the small bronchial mucosa below the segment, the cough was not obvious, or even no cough.

Sputum with blood or hemoptysis is also a common symptom of lung cancer, as the first symptom of about 30%. Due to the rich blood supply and brittle texture of tumor tissue, blood vessels rupture during severe cough, which may also be caused by local necrosis of tumor or vasculitis.

matters needing attention

Pay attention to ensure that the indoor environment is comfortable and hygienic, keep the indoor ventilation, beds and quilt covers clean and tidy. Especially for the elderly who are difficult to take care of themselves in the late stage of lung cancer, they should turn over regularly, scrub their bodies with warm water, and often massage the parts under their bodies when they lie down, so as to prevent the bedsores that the elderly often suffer from.
