820000 people get sick and 650000 die in a year. How does lung cancer, the "first killer" of cancer, come into being?
It can also adjust the pH value of the blood, filter out small thrombus formed in the vein, adjust the concentration of biological substances and drug……
Where do cancer cells come from and where do they go
term exposure to the above carcinogens can increase the risk of lung cancer.4. Air pollutionOutdoor pollution: such as industrial exhaust
automobile exhaust
haze and so on contain Class A carcinogens identified by the World Health Organization
Our human body contains trillions of cells
and these cells will experience apoptosis and death
in order to maintain the growth and repair of the body
the cells will divide.In general
mother cells divide into two daughter cells
which can be used to build new body tissues or to replace cells that die as a result of aging and injury. When the body no longer needs more daughter cells
cell division terminates
Passive smoking is also a risk factor for lung cancer
mainly in women.two。 Radiation factorNatural stone materials containing radon and other radioactive elements
such as granite
brick sand
cement and gypsum. Radioactive particles that decay radon can cause radiation damage to the human respiratory system and cause lung cancer
However
it is in the process of cell division that some cells have genetic mutations and their genetic factors are abnormal
causing these cells to produce "superpowers" that the human body cannot bear
