Get it removed immediately!!!!! I was treated for a Baker's cyst for ten years while the thing kept growing and growing. Finally, a dr took an x-ray, then ultra-sound, then MRI. I had a very LARGE malignant tumor......had a 50/50 chance of having my leg amputated. Followed up by radiation. Fooled them, tho. Still have leg, but after 7 years still painful. Have problems with numbness and swelling.
