Sorry to be appear thick .... but this is my question. I thought I was told that RA is not inherited but it appears from various blogs that it does, in fact, run in families. I am the first one in my family to have it (lucky old me!) and I have told my son that it is not inherited. Have I told him a porky pie? Us, as a family, have put it down to me having chemotherapy a couple of times some 26 years ago for non-hodgekins lymphoma, and the damage the drugs (massive MTX etc) have done to my system. Any ideas?
