So far, there is no way to completely cure cancer, and the development of the disease can only be controlled by medical means. No matter what kind of cancer will threaten human health, especially lung cancer, breast cancer, cervical cancer and liver cancer, as well as pancreatic cancer. As we all know, cancer has a certain genetic predisposition, so many people with a family history of cancer are worried, may wish to understand the related issues in detail.
<h1 class="pgc-h-arrow-right" data-track="2" what are the questions about cancer genetics and genetic testing >? </h1>
1, parents suffer from some kind of cancer, whether they will also suffer from cancer
Cancer is related to a variety of factors, in addition to genetic inheritance, but also closely related to lifestyle and surrounding environment. In the case of lung cancer, it is medically believed that lung cancer is related to smoking, exposure to harmful gases and heredity. Some cancers are heavily affected by genetic factors, including breast, colorectal and prostate cancer, and kidney cancer.
2. Which hereditary tumors need to be vigilant
Immediate family members, including parents and siblings, who have unfortunately been diagnosed with malignant tumors, especially ovarian cancer and breast cancer, as well as endometrial cancer and colon cancer, should go to the hospital for cancer screening, such as women regularly do breast molybdenum or breast B ultrasound to screen for breast cancer.
3. If a hereditary tumor has been diagnosed in the family, will the next generation definitely have a tumor?
Most hereditary tumors are autosomal dominant, and simply put, if the mother or father develops a hereditary tumor, the risk of inheritance to the child reaches 50%. No one can change genetic factors, but regular screening can control the progression of the disease, or kill cancer in the cradle.
4. The role of tumor gene detection
Tumor genetic testing can monitor tumor genetic susceptibility genes; liquid biopsy technology, sequencing free DNA for early screening of cancer; can also be used for tumor-targeted drug therapy; and can also be used to monitor tumor invasion and metastasis.
5. Whether all tumor patients need to do genetic testing
It is true that all tumor patients can do genetic testing. However, different diseases and stages, due to different purposes, different patients should do different genetic testing.
6. Whether genetic testing must use targeted drugs
Most cancers are not caused by simple genetic mutations, so patients with many cancers may not have a target for mutations. In time, the target with mutation was found through genetic testing, but the target has no clinical significance at this stage, in other words, the drug that has not been approved can be used.
7. After the tumor is treated, whether it needs to do genetic testing again
Genes within tumor tissue are constantly mutating, and the mutation process is completely random. The right treatment can reduce the frequency of mutations and avoid or reduce the occurrence of harmful mutations. Therefore, after treatment, under the premise of drug resistance or disease development, further genetic testing is needed to find out whether there are new genetic lesions in time, and then formulate a suitable treatment plan.
Tips
It can be seen that heredity dominates the occurrence and development of cancer, although the internal inheritance cannot be changed, but as long as the acquired care can reduce the risk of cancer. Correct bad life habits in time, refuse to smoke, drink and stay up late, and stay away from carcinogenic and carcinogenic substances. Pay attention to dietary diversity and dietary hygiene, maintain moderate exercise and adequate sleep to enhance disease resistance, and at the same time, you should regularly go to the hospital for corresponding cancer screening.
