[|Human|] Hi my name is Brenda. I have a lump on my forehead for the past 4 years. I saw a dermatologist and then did an X-ray. I was told it is a cyst. Though the size is still the same I am concerned whether I should get it removed or just ignore it. It is not painful
[|AI|]  Hello and welcome to Chat Doctor, An aspiration cytology of the lump should be done to assess the nature of the lump on the forehead. In aspiration cytology, the cells are sampled, spread on slide and stained with appropriate stains and studied microscopically. This investigation will determine whether the lesion is some tumor or a cyst. Further treatment will be planned after exact diagnosis is made. Any lump on the body should be excised. Thanks and take care Chat Doctor.
