Vodafone's plans for the base station on the corner of Grange Drive and Sapcote Drive appeared sunk when it was revealed the land belonged to Bargain Booze owner Amarjid Singh who refused permission.
But angry residents were shocked to discover a
second application this month just six metres away on an area belonging to Leicestershire Highways - affectively tying planning officials hands.
Catherine Langley, who lives just yards away in Grange Drive, is prepared to chain herself to the railings to stop the mast being built.
She said: "I have been diagnosed with malignant melinoma a kind of skin cancer, I'm in remission now, but if it comes back after they've built a phone mast, I will sue. They say there is no proof these phone masts cause cancer, but there's no smoke without fire.
"How would these people like it if it was right outside their house? It's ridiculous, it's just not worth the risk. This is my life they are talking about."
Frank Moore-Coltman, councillor for the ward, said: "There is very strong oppostition to it in the area. More than 200 people signed a petition against the last mast and there is a growing movement to oppose this one as well."
But this week it was revealed Vodafone had investigated several other places to site the mast including on top of Sherard School, Birch Wood Special School and both shops all of which refused.
It also considered putting it next to the Mars factory near the railway but that was too far away.
Dr Rob Matthews, from Vodafone, said: "The proposed Vodafone radio base station at Grange Drive / Sapcote Drive, Melton Mowbray is required to improve the 3G coverage to our customers in the area. This will provide our customers with access to mobile broadband with speeds similar to those offered by fixed line broadband suppliers."
In a letter to the school, Jenny Bye, from Waldon Telecom on behalf of Vodafone, addressed some of the teachers' fears.
She said the masts use electro magnetic fields which have been used for more than 70 years for television, radio and more and that there are more EMFs emitted by a fridge than a phone mast.
Cancer Research UK has investigated the link between mobile phones and cancer reporting that current evidence shows there is no risk from them or the masts.
Because of Government guidelines, Melton Council has few powers to oppose the application and it is likely to be approved early next year.
