What challenges remain in the field of cancer research?
Despite significant advancements, several challenges remain in cancer research:
Drug resistance: Cancer cells can develop resistance to treatments, making it difficult to achieve long-term remission. Tumor heterogeneity: Tumors can be composed of different cell types, each with its own genetic mutations, complicating treatment strategies. Metastasis: The spread of cancer to other parts of the body remains a major cause of cancer-related deaths, and understanding the mechanisms behind metastasis is crucial for developing effective treatments.
