Gene detection and targeted therapy

Genetic testing and targeted therapy are important components of precision medicine, revolutionizing the diagnosis and treatment of diseases such as cancer.

Genetic testing can help determine whether individuals carry specific genetic mutations that may be closely related to the onset, development and response to treatment. By analyzing the genes of patients 'tumor cells, key genetic variants associated with tumor growth, metastasis, etc. can be discovered. This helps doctors to more accurately understand the nature and characteristics of diseases and formulate more personalized treatment plans. For example, in lung cancer, EGFR gene mutations can be detected by genetic testing, and specific targeted drugs can be used to treat these mutations, significantly improving the effectiveness of treatment.

Targeted therapy is a treatment method that targets specific gene mutations or molecular targets based on the results of genetic testing. Targeted therapy has stronger specificity and fewer side effects than traditional chemotherapy and radiotherapy. Herceptin, a targeted drug for HER2-positive breast cancer, specifically binds to HER2 protein, inhibiting tumor cell growth and proliferation.

Gene testing and targeted therapy are important advances in modern medicine, bringing better treatment options and survival hope to patients. In the future, they will continue to drive the transformation of medical models towards more precise and personalized development.
