CB1209; I wasn't concern about the things that you were telling me until I read that the lump has started to appear in your thigh. The areas that you describe are the area of the lymphnodes. The lymphnodes are basically the "dumping ground" for the Lymphatic system. The lymphatic system has three interrelated functions: (1) removal of excess fluids from body tissues, (2) absorption of fatty acids and subsequent transport of fat, chyle, to the circulatory system and, (3) production of immune cells (such as lymphocytes, monocytes, and antibody producing cells called plasma cells). When testing for the spread or the presence of cancer the doctors usually will biopsy some lymphnodes. Lymphnodes can become enlarged for several reasons. One being cancer, and others of other diseases and even cysts. I strongly urge you to seek medical attention. it could be nothing but it could be something that you might need further treatment for. I will pose a question to you; What is your life worth? I'm sure you would spend a little money to have a piece of mind knowing that these lumps are cysts or something other that cancer. But you will never know until you have the lumps investigated. I hope I haven't scared or confused you with this lengthy reply. I just want you to understand that this could be something that needs medical attention. Take care of yourself, we only get one go-round in life.
