Cancers linked to the development of second cancers

No matter what type of cancer is treated, treatments such as radiation and chemotherapy can lead to a second cancer in the long run. Because it can take many years for treatment-related cancers to develop, they have been studied best in those who have lived a long time after being treated. Successfully treating a first cancer gives a second cancer the time (and the chance) to develop. The cancers discussed in this section were some of the first cancers in which treatment led to long-term survival. It is likely that we will see second cancers developing after some other cancers as treatment and survival improves.
