AI systems analyze genomic data to identify actionable mutations and recommend targeted therapies.
Examples include:
- EGFR-targeted therapies for lung cancer
- HER2-targeted treatments for breast cancer
- BRAF inhibitors for melanoma
By matching patients with therapies that target specific molecular abnormalities, precision medicine improves treatment effectiveness and minimizes unnecessary side effects.
Machine Learning and Predictive Analytics
Machine learning, a subset of AI, enables systems to learn from data and improve performance over time.
Predicting Cancer Risk
Predictive models can analyze risk factors such as:
- Family history
- Genetic predisposition
- Lifestyle habits
- Environmental exposures
- Medical records
These insights help healthcare providers identify individuals at higher risk and implement preventive strategies earlier.
Forecasting Treatment Outcomes
Machine learning algorithms can predict:
- Treatment response
- Disease progression
- Recurrence risk
- Survival outcomes
These predictions support personalized treatment planning and help physicians select the most appropriate interventions.
For patients, this means more informed decision-making and improved confidence in treatment choices.
Digital Pathology and AI-Assisted Diagnostics
Pathology plays a crucial role in cancer diagnosis. Traditionally, pathologists examine tissue samples under microscopes.
The Rise of Digital Pathology
Digital pathology converts glass slides into high-resolution digital images that can be stored, shared, and analyzed electronically.
