Lao Zhang was diagnosed with prostate cancer. One day, he overheard his son calling: "I want to go for genetic testing, I heard that prostate cancer may be hereditary, it is better to check it in advance." ”
The person on the other end of the phone said, "Haven't you heard that cancer is hereditary?" ”
The son said: "My friend's father had liver cancer, and my friend was also diagnosed with liver cancer 5 years after his father's death, and I think it should be a genetic problem." ”
Lao Zhang's heart is not a taste, cancer is not a genetic disease, why is there a person with the same cancer in the family?
Cancer is not inherited, but some cancers are genetically predisposed.
Generally speaking, some people have an inherited gene mutation in their body, and this gene mutation causes cancer.
For exampleMutations in the BRCA2 and BRCA0 genes increase the risk of breast and ovarian cancer.
American Hollywood superstar Angelina Jolie has a genetic defect gene BRCA1, and in order to reduce her risk of breast cancer and ovarian cancer, she underwent surgery to remove both breasts, part of the ovaries and fallopian tubes.
But genetics isn't the only risk factor. If you live in the same living environment and have the same habits, you may also develop the same cancer.
For example, the small amount of radon gas contained in decoration materials such as house foundations, granite, brick sand, cement and gypsum can increase the risk of lung cancer.If someone in your family smokes and regularly smells secondhand smoke, it also increases the risk of lung cancer.
So, which cancers are genetically predisposed?
1. Breast cancer and ovarian cancer
Mutations in the BRCA30 and BRCA0 genes increase the risk of hereditary breast cancer. If there is a family history of breast cancer and ovarian cancer, it is recommended that women advance the screening age to 0 years.
2. Straight gut cancer
Lynch syndrome, also known as hereditary nonpolyposis colorectal cancer, increases the risk of colorectal cancer and several other cancers if you have this disease.
3. Stomach cancer
If you have a mutation in the CDH1 gene, you may develop hereditary diffuse gastric cancer.
In addition, family meals are not divided into separate meals, and chopsticks are not used, and if one of them is H. pylori positive, then the family member will be infected with Helicobacter pylori, which will increase the risk of stomach cancer.
4. Prostate cancer
The familial incidence of prostate cancer is relatively high, so it is recommended to pay attention to the maintenance of the prostate. Don't hold your urine and don't sit for long periods of time; Pay attention to hygiene to avoid prostatitis; The diet should be light and less spicy and stimulating food.
5. Melanoma: If you have a mutation in the CDKN2A gene, you may develop familial melanin.
It can only be said that if there are more than one person in the family who suffers from cancer, it is recommended that you can calculate the probability of developing these cancers through genetic testing.
If you already have some uncomfortable symptoms, you can check for cancer with the tests recommended by the Home Cancer Prevention Guideline:
Generation 3 IVF is possible. This is a technique in which chromosomal or genetic testing is performed on the cells of an embryo before it is implanted into the mother's body.
If an abnormality is found in the chromosomes or genes of the embryos, they can choose not to transfer these embryos and only those that test normally, helping couples to have a healthy child.
This IVF technique is ideal for older couples who have undergone embryonic termination or spontaneous abortion and where one of the couples is known to carry abnormal chromosomes or genes.
Cancers such as breast cancer, ovarian cancer, colorectal cancer, and stomach cancer are associated with hereditary gene mutations. In addition to genetic factors, shared living environments and similar lifestyle habits can also lead to multiple people in the family suffering from the same type of cancer.
If there is a family history of cancer, genetic testing can be used to assess the individual's risk, and if symptoms occur, cancer screening is required.
In order to avoid the "genetic" of cancer, the third generation of IVF technology can be adopted to avoid passing on the abnormal gene to the child.
