Whenever we eat things rich in fat or specially, animal fat our body produces some fat lumps. Those lumps are mostly seen in healthy people and women suffer from fat lumps at their breast usually. If they are painless then you should not bother too much about them. But, if they are paining then you should start walking for one hour every day in your routine and that should be followed by a glass of water boiled with Cumin. It may take a long time, maybe up to a year, but these lumps are possible to be dissolved.
