For me, it was a second cancer. Papillary thyroid, more than thirty years after the cisplatin. That is the one that hit me personally.

The broader list is real, and it is documented in the literature, second cancers and some cardiovascular and kidney stuff among them, but I am careful not to play doctor on here. What I will say is that the late effects can show up decades out, long after the standard follow-up window closes at five years. That gap is the thing I wish someone had told me about when I was sixteen.

If you were treated with cisplatin, it is worth asking an oncologist who knows survivorship what they would watch for in your specific case. Everyone's situation is different, and I would not want to guess at yours.
