Yes, smoking doesn’t necessarily cause cancer! But read this first…

(Here, play "Quit Smoking" by Li Ronghao)

I can't quit smoking.

Is there any way to minimize the damage?

Or avoid getting involved in lung cancer?

Tian Bo, thoracic surgeon at Sichuan Cancer Hospital

Let’s talk about the relationship between heavy smokers and lung cancer.

Why do some long-term smokers not die from lung cancer?

When the amount of smoking exceeds a certain critical point, it will trigger the self-protection mechanism in the smoker's body and enter a stable period of DNA mutation. It is this powerful DNA repair ability that helps resist the damage caused by smoking that leads to lung cancer. Therefore, many smokers do not eventually develop lung cancer.

Don't be happy too soon!

Related studies have also shown that:

Among long-term smokers,

One in six people will suffer from lung cancer.

What's even more terrifying is that

The most common problem for "old smokers" is -

Squamous cell carcinoma of the lung.

It is a type of lung cancer other than lung adenocarcinoma

The second most common malignant tumor

It often occurs near the hilum of the lung.

It is easy to invade the nearby trachea.

Causes symptoms such as chest tightness and shortness of breath.

Moreover, it grows fast.

Often huge tumors can form.

Take your "huge" size

Compression and infiltration of surrounding organ tissues.

What should the "old smoker" do?

Avoid lung cancer?

first

Be careful of the following people

The high-risk group for lung cancer is between 50 and 74 years old.

And at least one of the following conditions is met:

Smoking pack-years ≥ 30 pack-years,

Including those who had ever smoked ≥30 pack-years,

But they have quit smoking for less than 15 years;

Living with the above conditions

Or work in the same room and have been exposed to passive smoking for more than 20 years

Have chronic obstructive pulmonary disease;

Have a history of occupational exposure for ≥ 1 year,

Including exposure to

Asbestos, radon, beryllium, chromium, cadmium, silicon,

soot and soot;

If the above conditions are met,

Do you still want to escape lung cancer?

Then you must remember,

Low-dose spiral CT (LDCT) was performed annually.

Or you can go to the thoracic surgery consultation clinic and follow the doctor's instructions.

You should also pay more attention to your physical condition.

Especially the following three situations occur!

No matter how long you smoke,

The benefits of quitting smoking are almost immediate.

The lungs can work better,
