A stomach growth is causing fluid to accumulate in my mother's stomach. What to do?

Hi doctor,

My mom had surgery to remove her fibroid alongside her womb. Later we discovered that she also had gallstones. So another surgery was performed on her to remove her gallbladder. After this, her stomach became so hard and could barely eat anything. After the gallbladder removal, she was told it could have been cancerous, so as of now, she has taken about 10 rounds of chemotherapy. The injectable ones are about six. She also took the pills, which made her palms and other body parts dark, but now they are back to normal. Currently, she is left with her last round of chemotherapy, and it is the injectable one scheduled for next month. After her gallbladder removal due to the swelling and hardening, she could not eat well. We were then referred to a radiologist who said she had some fluid inside her stomach to drain that has taken months.

We took a CT scan which showed she had a small growth in her stomach area, but doctors failed to tell us what it is. The doctor then told us it would be best if she undergoes another surgery to remove the growth that is causing the fluid in her stomach. After the surgery, we were told he could not remove it all and that if he does it, my mom will not be able to urinate or excrete unless they give her a tube. He stitched where he cut after the surgery, but fluid keeps coming from it every day, so my mother constantly goes for dressing. Now we have been referred back to the radiologist. I am afraid we do not know what else to do. Please help.
