Caroline Aherne and her brother Patrick were both diagnosed with a type of eye cancer as babies.
Aherne's sight was saved, but her brother had to have his right eye removed to prevent the cancer spreading.
Known as retinoblastoma, it is genetic and can lead to children losing both their eyes and at higher risk of developing further cancers in adulthood.
Aherne, who has been working with the trust on a campaign to highlight signs of the condition, said, "It is absolutely crucial that parents are aware of this horrible cancer."
