What Are the Limitations of DNA Profiling in Cancer?
Despite its many advantages, DNA profiling in cancer has limitations. One challenge is the heterogeneity of cancer, meaning that different cells within the same tumor can have diverse genetic profiles. This complexity can make it difficult to identify a single target for treatment. Additionally, not all genetic mutations are currently understood, limiting the ability to interpret some profiling results. Furthermore, DNA profiling can be costly and may not be universally accessible, posing barriers to widespread adoption in clinical practice.
