Uterine Fibroid. Had all my tests done!

Hello Sir, I am detected with large abdomen mass of 25 cm. I had all my tests done regarding cancer. Out of that only 1 test has come more that is CA 125 is 2171 that is high so they suspect ovary cancer but my HE4 is 43.4. Other organs tests are normal. Besides this I had never had a period issues or irregularity. No other symptoms except the hardness of the mass around the belly button but other areas are normal. I am having moderate ascitis around the mass and pleural effusion of my right lungs. I had also tested the liquid from my lungs and stomach. No atypical cells are seen. Yesterday I did my biospy. My abdomen mass is hard so it was bit difficult to take out the tissue. But they took out in 3rd and 4 th time. Well, I am not feeling any pain. Only little bit in that portion. But my belly is swollen so is it natural?
