Can genetic testing predict cancer?

Cancer gene testing can provide some reference information about cancer, but its predictive ability is limited and it is generally impossible to predict whether cancer will occur.

Cancer gene testing is a technology based on gene sequencing, which detects genes in tumor tissues to understand the process of tumor occurrence, development and metastasis. The results of tumor gene testing usually include information such as gene mutation types and gene expression levels. Such results can reflect the genetic variation of tumor cells and provide reference for doctors to diagnose and treat. However, gene test results cannot directly predict whether a person will develop cancer, because the occurrence and development of cancer are affected by many factors.

When facing the results of tumor gene test, we should maintain rationality and not rely too much on the results. Instead, we should combine other diagnostic methods to make a comprehensive judgment.
