<s>[INST] I had endometrial cancer diagnosed in december2010 and have undergone radiotherapy for 4 weeks,cisplatin chemotherapy for each of those 4weeks and I am now half way through taxol and carboplatin chemotherapy due to finish on 3rd May.I had grade 2 cancer that had gone into the cervix but nowhere else save that in the wash prior to my full hysterectomy they found a few cancer cells.I seem tto have developed low back pain going down my right leg when I am active.Could this be cancer or have I just twisted my back.I have had some similar back trouble in years past. [/INST] Hi, dairy have gone through your question. I can understand your concern. You have history of endometrial cancer, and it also involves cervix.  You may have back pain due to cancer or some spinal problem.  Furthermore, you should go for MRI spine once.  It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
