Tumor targeting is a research area focused on developing strategies and technologies to specifically deliver therapeutic agents or imaging probes to cancerous cells while sparing healthy tissue. This approach is important in cancer treatment as it can enhance the efficacy of therapies, reduce side effects, and improve patient outcomes. Different tumor targeting strategies include the use of targeted drug delivery systems, such as nanoparticles or antibodies, as well as imaging techniques like positron emission tomography (PET) or magnetic resonance imaging (MRI) to accurately locate tumors for treatment. Researchers in this field aim to improve the precision and specificity of cancer treatments, ultimately leading to more effective therapies with fewer adverse effects.
