Final answer:
False, anaplastic carcinoma, especially anaplastic thyroid carcinoma, is associated with radiation exposure, with numerous studies supporting the link between radiation and increased risk for this aggressive form of cancer.
Step-by-step explanation:
The statement 'Anaplastic carcinoma is not associated with poor radiation exposure' is false. Anaplastic carcinoma, particularly anaplastic thyroid carcinoma, is a highly aggressive form of cancer that can be associated with exposure to radiation. Several studies suggest that exposure to radiation, especially in childhood, increases the risk of developing thyroid cancer, including the anaplastic subtype. Anaplastic thyroid carcinoma is characterized by its rapid growth and can be difficult to treat effectively with conventional methods such as surgery, because it often metastasizes early. However, anaplastic carcinomas from different tissues may have different risk factors, although poor radiation exposure remains a well-recognized risk factor for many types. Therefore, it is important to be aware of the risks associated with radiation exposure and its link to the development of aggressive cancers such as anaplastic carcinoma.
