What are the challenges faced in cancer research and treatment?
Despite the progress made, several challenges remain in cancer research and treatment. One significant challenge is the heterogeneity of cancer; even within the same type of cancer, tumors can vary greatly between patients. This variability makes it difficult to develop one-size-fits-all treatments. Additionally, drug resistance is a major issue, as cancer cells can evolve to become resistant to therapies over time. Finally, the high cost of new treatments poses a barrier to access for many patients, highlighting the need for more affordable treatment options.
