I have CFS (3 years) and am now dealing with breast cancer, fortunately caught in an early stage (remember to get your mammograms!...that's how mine was found). The biopsy, surgery, and trying to deal with all of the doctor appointments, the emotions, the options and decisions, has heavily impacted my CFS. I was previously functioning in the home environment, but unable to work. Now I'm so tired (just had surgery a week ago) I'm staying in my pajamas all day, resting a lot more. Coming up are radiation and possibly chemo. Has anyone experienced something similar? How did you manage it? Fighting cancer takes a lot of energy. Also, has anyone every heard of a connection between CFS and cancer? The immune system is so involved with both. Thanks for your input.
