a urinary tract infection (uti) is caused when bacteria infect the urethra (the internal tube urine passes through when you pee). utis can be caused by many things but stomach cancer is not a likely culprit. stomach cancer occurs in the lining of the stomach. cancer in general is the growth of abnormal (malignant) cells. because these cells are not bacterial it's unlikely they could cause a uti. some treatments for stomach cancer could possibly cause a uti. if you or someone you know has stomach cancer and developed a uti you might ask the oncologist if there is any relationship between the cancer treatment and the urinary tract infection. i hope you are not experiencing stomach cancer but if you are i wish you all the best.
can chronic uti's & stomach cancer be coralted?
