What are some challenges in cancer drug and therapy testing?
Several challenges exist in cancer drug and therapy testing:
- Heterogeneity of Cancer: Cancer is not a single disease but a collection of related diseases, each with its own characteristics, making it difficult to develop one-size-fits-all treatments. - Drug Resistance: Tumors can develop resistance to therapies over time, reducing their effectiveness. - Recruitment Difficulties: Enrolling enough participants for clinical trials, especially for rare cancers, can be challenging. - High Costs and Time: The entire process of developing and testing new drugs is costly and time-consuming, often taking many years and significant financial investment.
