What are the primary challenges in early detection of cancer?
Early detection of cancer is critical for successful treatment, yet it poses significant challenges. One of the main issues is the lack of effective screening methods for certain types of cancer, such as pancreatic and ovarian cancers. Additionally, many cancers do not present symptoms until they have reached an advanced stage, making early detection difficult. There is also a need for more accessible and affordable screening methods to ensure that individuals from all socioeconomic backgrounds can benefit.
