Though Marvel did do a cancer storyline at least three times to my knowledge. It's how Mar-Vell died (his powers meant chemotherapy didn't work), the other two are Firestar (who got it from her own powers) and Jane Foster (who died because her Thor powers were negating the chemo, but she was resurrected by Odin, gave up being Thor and recovered, later becoming Valkyrie).
