Molecular diagnostics improve cancer care by identifying inherited risks and personalizing treatment. Advanced techniques like DNA microarrays and proteomics enable customized therapies for better patient outcomes.

Area of Science:

  • Oncology
  • Molecular Diagnostics
  • Genetics

Background:

  • Traditional cancer diagnostics like histology and staging have limitations in predicting treatment response.
  • Molecular diagnostics offer advancements in identifying inherited cancer risks and improving prognostic accuracy.
  • Current molecular tests focus on single markers (e.g., estrogen receptor, HER2), with broader systems under development.

Purpose of the Study:

  • To highlight the advancements in molecular diagnostics for cancer.
  • To explain the limitations of traditional cancer diagnostic methods.
  • To discuss the potential of multi-marker diagnostic systems for personalized cancer therapy.

Main Methods:

  • Review of traditional cancer diagnostic techniques.
  • Discussion of molecular-based technologies for risk assessment and prognosis.
