Recently, the passing of the legendary actor Wu Maoda due to liver cancer has made many people start to pay attention to liver health and protection.

However, within the cancer group, lung cancer is even known as the king of cancers, and the number of deaths from lung cancer each year is not few.

According to the results of multiple studies in recent years, the affected group of lung cancer has gradually shifted from the middle-aged and elderly group to non-smoking young people, which forces people to think deeply.

The person who smokes and harms others is no longer harming themselves, but harming everyone around them who is usually close.

According to Dr. Michael Wart of the Lung Disease and Critical Care Medicine at the Knas Medical Center of Ohio State University, "the incidence rate of lung cancer in people aged 30 to 40 who have never smoked once."

In a paper published in the Journal of the National Cancer Institute in July 2017, a piece of data was also mentioned. The proportion of never-smokers diagnosed with non-small cell lung cancer increased from 8% between 1990 and 1995 to 14.9% in 2011-2013, and this number may still be rising year by year.

This inevitably brings to mind a news report from the past two years, about an 8-year-old girl in Jinan, Shandong, who was diagnosed with late-stage lung cancer. The news caused an uproar among the public.

After the doctor's inquiry, the child's father learned the true culprit that had caused his daughter to develop lung cancer—it was the secondhand smoke from the cigarette he constantly held in his mouth. Upon hearing this from the doctor, the father broke down in tears on the spot.

If you want to avoid such a situation, you must understand a fact: what are the early symptoms of cancer. Never wait until it's too late to regret it.

According to clinical data reports over the years, there have been 5 early symptoms of lung cancer:

Shortness of Breath

Shortness of breath is one of the main symptoms of COVID-19, so it has also been given more attention recently.

%% But this is also one of the early symptoms of lung cancer.

If you usually have no problem climbing up and down, but suddenly need to pant after walking a few steps up the stairs during a certain period, then this could be one of the early symptoms of a serious problem in the lungs.

Rapid heartbeat

Under normal circumstances, the human heart rate increases only when exercising.

This usually occurs only with a certain level of physical activity, but if slight movement, such as walking a few steps faster, causes the heart rate to increase to an alarming level, it is likely one of the early warning signs of lung cancer.

Chronic cough

Among many teachers, there have been cases of chronic cough caused by vocal strain, but it is usually manifested in the throat.

If it's a chronic cough caused by lung discomfort and has lasted for 6 weeks or even longer, it's best to get an X-ray to check the condition of your lungs.

Coughing up blood

If the sputum coughed up contains streaks of blood, or even if there is no sputum but blood is coughed up, it is still not a good sign.

Must go to the hospital for check-up immediately.

The reasons may include lung cancer to bronchitis, or viral infection, bacterial infection, etc.

Unexplained weight change, fever

Just appeared sudden weight loss without any other symptoms, and inexplicably had a fever.

So it's important to pay attention to whether it's a hidden illness, or even early symptoms of lung cancer.

After experiencing any of these 5 conditions, it's always a good idea to go to the hospital for a check-up.

Don't let secondhand smoke become your last memory.
