Cancer Council Tasmania has urged people to be wary following a spate of bogus calls.
Chief executive officer Penny Egan said the council had been contacted by several people who had been called and asked to make donations over the phone.
Mrs Egan said the not-for-profit organisation never asked for financial donations over the phone.
''We have had people telephone at Launceston, George Town and Nubeena,'' Mrs Egan said.
''One caller told us that the person who called her and her neighbour at George Town was very well spoken and quite pushy.
''In one case the caller claimed they wanted money towards accommodation for people who had cancer because the council had lost a government grant."
Mrs Egan said that one man made a donation after receiving a call and it showed up on his bank statement but was not to the Cancer Council, as he was told.
Mrs Egan said that anyone who wished to make donations did so online or visiting a council office in Hobart, Launceston or Ulverstone.
