Does Stage 4 Cancer Mean That It Is Terminal? The risk of secondary cancers after radiation therapy has become an important issue, mainly because advanced treatment techniques such as 3-D conformal radiation therapy (CRT) and intensity-modulated radiation therapy (IMRT) tend to increase the radiation dose to out-of-field organs. These “secondary” cancers do not mean that the prostate cancer had spread; on the contrary, a new cancer has begun in a nearby organ (bladder, colon, rectum) because of exposure to radiation. 10 Similarly, the relative risks of developing secondary cancer for patients surviving and years after EBRT for prostate cancer were estimated to be … A way to further understand this damage — and to understand how cancer may develop both initially and in response to cancer treatments, is to look at this reaction. secondary cancer after the treatment. The risk of secondary cancers varies considerably between different cancer types.
