Only a portion developed cancer of a similar type
Of the 1,315 adolescent and young adult cancer survivors, 71 were diagnosed with an SMN during the follow up period.
Some of the cancer survivors developed a hematological nonsolid SMN, similar to their original cancer. However, this was only 28% of the study population who developed cancer. The majority of them developed solid SMNs, rather different from their original cancer. The two most prevalent solid SMNs were breast cancer and gastrointestinal cancer.
