Rare tumors are types of cancer that occur infrequently and affect a small percentage of the population. These tumors can be challenging to diagnose and treat due to their rarity, which can lead to limited research and understanding of the disease. Research in this area focuses on identifying the causes of rare tumors, developing effective treatment strategies, and improving outcomes for patients with these types of cancer. Collaborative efforts among researchers, healthcare providers, and patient advocacy groups are often necessary to advance knowledge and improve care for individuals with rare tumors.
