I am having lower abdominal pains, i.e. gas pains. I feel like I have to have a stool, but only have gas; yet I am having regular stools. I had fallopian tube cancer in 2015, with 6 rounds of chemo. My last chemo was Nov 2015. I still have a port and have bloodwork each month. My last bloodwork showed that my CA 125 is now 62.5, in the danger zone. I had a CT scan today, waiting for results on Monday. Please give me your opinion of what might be going on. I hope its not cancer again.
