Definitions for "Radiosensitive"
A cancer that responds well to radiotherapy is said to be radiosensitive.
Some biological cells divide more rapidly than others. these are the ones that are more likely to suffer damage from ionising radiation. They do not have sufficient time to 'repair damage' before they are required to divide again. Cancer cells fall into this category.
