On November 17-20, 2022, the 2022 Chinese Oncology Congress (CCO), hosted by the Chinese Anti-Cancer Association and organized by Zhejiang Cancer Hospital, Zhejiang Anti-Cancer Association, Zhejiang Cancer Foundation, and China Institute of Integrative Medicine Development Strategy, was held
in Hangzhou, Zhejiang.
Well-known academicians of the Chinese Academy of Medicine and the Chinese Academy of Sciences and leaders of various professional disciplines in China will attend the meeting, focusing on cancer prevention and anti-cancer plans, sharing cutting-edge information, discussing the latest strategies, and exploring future trends
.
During the meeting, we were honored to invite Professor Shi Jianguo of the Fourth Military Medical University to share the relevant content of early cancer screening for us.

Medical Pulse: Malignant tumors have become one of the main public problems threatening the health of our population, why should we do early screening for cancer? What is the significance of early cancer screening?
Professor Shi Jianguo
Cancer needs to be screened early, which is determined by the underlying logic of cancer
.
The human body is a three-dimensional cell culture system, if the normal human body is compared to a rice field, a seed mutation (normal cells mutate into malignant tumor cells), will not cause the body to produce too strong a reaction
.
In the presence of one or two malignant tumor cells, or when the number of malignant tumor cells increases, forming tissue masses of several millimeters or even centimeters in size, the body generally does not show obvious clinical symptoms
.
For a long time, the biggest symptom of a tumor is the absence of symptoms
.
Considering the great harm that tumors may cause to the human body in the future, we need to remove them at an early stage, which relies on early screening
.
With the help of existing screening methods such as body fluid examination or imaging examination (CT), the signs of tumor development can be detected as early as possible, so as to track the changes of tumor lesions and intervene
in time.
Therefore, only early screening can achieve early diagnosis and treatment
of tumors.
Medical Pulse: Early screening, early detection and early treatment play an important role in tumor prevention and control, which groups of people need to be screened early?
Professor Shi Jianguo
Some people should be screened
for cancer early.
The first is that people with genetic backgrounds, especially those who have been confirmed by genetic testing to have tumor susceptibility genes, should be screened
early because of their higher risk of cancer.
This is followed by people
with family members with cancer.
This is different from the genetic background just mentioned, which may be due to the environmental state of this group of people, the way of life and behavior of the family, etc.
, which leads to the occurrence of cancer, so this group should also be screened
early.
There are also people affected by occupational environments such as radiation, chemicals, etc.
, who are at higher risk of cancer and should also be screened
early.
Finally, people with some specific behaviors should also be screened for early cancer of specific organs, for example, poor people in the past have a higher risk of esophageal cancer, because the traditional poor diet is coarse, hard, hot, mildew, high salt, and more wolf, so the esophageal transport line has more chances of damage, more chances of damage are more chances of repair, more chances of repair are more opportunities for hyperplasia, more opportunities for hyperplasia are more chances of mutation, so there are more
chances of cancer.
Therefore, it is also necessary for people in specific areas or specific survival conditions to be screened
for cancer early.
Yimaitong: Early cancer screening is the best way to improve the survival rate of cancer patients in the "Healthy China 2030" plan, what challenges do you think there are in early cancer screening in China? What is the future hold?
Professor Shi Jianguo
At present, China's early cancer screening still faces two major challenges
.
First, screening methods need to be enriched
.
The development of screening methods relies on the advancement of science and technology, which can extend the human senses, so as to detect some tumors that are not visible now, and facilitate early intervention
by clinicians.
Second, residents' awareness of prevention needs to be improved
.
Although the awareness of cancer among social groups has improved, there is still much room
for improvement in improving prevention or early screening.
This also requires medical media workers and medical professionals to publicize more, form an atmosphere, a culture, so that even under existing screening conditions, a large number of undetected early cancers can be detected
