I was recently dx high grade myxofibrosarcoma after surgery to remove a lump, at the right hip, thought to be benign. I found the lump only about 8 months ago and my gp based on MRI thought it was most likely benign and no biopsy was taken. Well, we should have approached it with the potential high risk in mind. Now, we have to seek expert help. Any suggestions and experience in potential spreading of this soft tissue sarcoma? I read that chemo is not particularly effective.
