Who is prone to prostate cancer? In recent years, the incidence rate of prostate cancer is on the rise, so we should pay attention to it. So who is prone to prostate cancer? The following series will introduce you.
What kind of people are more prone to prostate cancer?
It is reported that after gene research of 4000 domestic prostate cancer patients and healthy people, three prostate cancer susceptibility gene loci unique to Chinese people have been found. People with these loci have a higher risk of prostate cancer than ordinary people. If there are three sites at the same time, the risk of prostate cancer is 2.26 times higher than that of normal people.
1. Whether cancer is easy to develop varies from person to person
The so-called gene locus is the specific position of the gene in the human chromosome. The susceptibility gene loci found by researchers have a cumulative effect, that is, the more dangerous the loci are, the higher the risk of prostate cancer. The data shows that only one locus has increased by 42%. If there are three loci at the same time, the individual's risk of prostate cancer is 2.26 times higher than that of normal people.
Some people are prone to cancer, while others are not. Those who are prone to cancer are those who are prone to cancer. For example, it is generally recommended that men begin screening for prostate cancer at the age of 50, while men with a family history of prostate cancer begin screening at the age of 40, indicating that the risk of cancer is really suitable for people; Research shows that mutations in related genes will increase the risk of prostate cancer. The more genetic changes, the greater the possibility of cancer. Professor Zhang said that the question of this study is what genes make people prone to prostate cancer?
99.9% of the human genome is the same. NA has only a small sequence composition (0.1%) difference. This 0.1% difference determines everyone's physical characteristics such as height, weight, appearance, skin color, as well as whether they are prone to cancer and what drugs they are sensitive to.
This difference is expressed in professional terms as single nucleotide polymorphism (SNp), which affects whether people will suffer from certain diseases and the onset time. Theoretically, as long as they are exposed to the carcinogenic environment for a long time, everyone may eventually develop cancer, but the susceptible population is more sensitive to the carcinogenic environmental factors, making them more prone to cancer in a short time.
2. External factors are inducements, and lifestyle is crucial
Research shows that if one of the father's or brother's immediate male relatives has prostate cancer, the probability of other men in the family suffering from prostate cancer is twice that of the ordinary people; If there are two people, the probability is three times. This indicates that the occurrence of prostate cancer is related to genes.
