Despite advances in technology, drug screening for cancer faces several challenges:
Complexity of Cancer Biology: Cancer is not a single disease but a collection of related diseases with diverse genetic and molecular profiles, making it difficult to find one-size-fits-all treatments. Drug Resistance: Cancer cells can develop resistance to drugs through various mechanisms, such as gene mutations or changes in drug metabolism. Off-Target Effects: Compounds may interact with targets other than the intended one, leading to side effects and toxicity. Cost and Time: The drug discovery process is expensive and time-consuming, often taking years and significant financial investment to bring a new drug to market.
