What does genetic testing for tumors mean?

Genetic testing for tumors involves analyzing and examining an individual's genome to understand their risk of developing tumors and potential hereditary factors. The detailed explanation is as follows:

Genetic tumor testing can help doctors and patients better understand tumor development and treatment options, providing personalized medical care. This process typically begins by collecting a patient's blood or saliva sample to obtain DNA, which is the key step in genetic testing. The DNA is then extracted from the sample and sequenced using high-throughput sequencing technologies to determine the individual's genomic sequence. The sequencing data is analyzed and compared against known genomic databases to identify gene variants associated with tumors. Based on these findings, the individual's risk of developing tumors and possible genetic factors are evaluated, and appropriate medical recommendations and care plans are provided. Genetic testing enables physicians to understand the specific genetic mutations in a tumor, thereby guiding personalized treatment strategies. For example, certain genetic mutations may influence sensitivity or resistance to specific drugs, allowing clinicians to select more effective therapies through genetic testing.
