I have very many fatty tissue lumps under the skin, all over my body. I was told by a GP, about 20 years ago, that they were polyps ....fatty tissue that some people are more prone to than others. Since that time the numbers on my body have increase and the sizes of some have increased. They are not painful, more unsightly in the summer as I have 3 or 4 on my arms. I recently read an article identigying 9 Types of Polyps ...none of which described mine (which are all external, not internal. So what are mine & what is the cause?? I am female, age 60,no health problems other that well controlled Diabetes Type 1, for 40 years.
