Guernsey's health department is urging all users or former users of a controversial cancer drug GcMAF to contact their GP.
The unlicenced drug has been banned after its UK factory closed amid fears materials used aren't fit for human consumption.
Hundreds of islanders have already pleaded with politicians and health officials to have the ban lifted.
Campaigners wanting the ban on importing GcMAF lifted are meeting for a second time this evening.
Dozens attended a public meeting earlier this month after the unlicensed drug was banned by UK health officials and branded a 'significant risk to health'.
David Noakes, the Guernsey businessman behind it, met many of the supporters who claim the so-called 'cancer cure' is the reason they're still alive.
The meeting will be held at St Pierre Park Hotel at 7.30pm
The weekend event coincides with International Pride Month and the 51st anniversary of the Stonewall riots.
The scheme has been backed by the island's Lieutenant-Governor, and is the first of its kind in the Channel Islands.
Sunny spells and isolated light showers. After dusk fair spells with isolated showers.
