What Challenges Exist in Developing New Cancer Drugs?
Despite significant progress, several challenges remain:
- Resistance: Cancer cells can develop resistance to drugs, rendering treatments ineffective over time. - Tumor Heterogeneity: The genetic diversity within tumors makes it difficult to develop one-size-fits-all treatments. - Side Effects: Balancing the effectiveness of a drug with its potential side effects is a continual challenge. - Cost: The high cost of research and development often translates to expensive treatments, limiting access for many patients.
