I found a lump in the fold of my thigh and groin about a month ago. It was not, and still is not sore but has grown in size and now my clothes are very lose on me and I have not changed my diet or exercise routine in this time. I bought some new trousers about 10 days ago and now I have put 3 safety pins in one side to keep them up! Am concerned as loss of weight has triggered my worries. Appreciate any help or advice, thank you x
