fluid in lungs and pain in chest and waist

Hi,
   My mom had a pain in chest (especially in lower three right ribs) and pain in waist. The pain in waist is on right side as well and it would start in front and radiate towards back. She went to see a doctor about a month ago and nothing came out in ECG and X-ray reports. But few days back her pain started becoming severe and intolerable. Then she went to see another doctor and he sent her for chest X-ray and ultrasound. In ultrasound report it was discovered that she has water accumalated under lungs and the doctor said its TB. But the doctor has no answer why there is such a severe pain in waist. We went to another doctor for a second opinion and after getting blood test, digital X-ray and ultrasound the decided to take out the water from the body. They took out about 900ml. of water and doctor started TB medicines. He also said that if there is further fluid accumulation then there is a 50% chance of cancer otherwise its TB. He also referred her to a cancer sepcialist and the cancer specialist said that since the color of fluid that was taken out from body was little reddish in color so it favors the chance of lung cancer. Now with all these reports I am compltely confused and do not know what to do. None of these doctors told me the reason of fluid accumulation and pain in the waist. Also, if its a cancer then what's the best test to confirm it and can it be cured. I would highly appreciate any of your suggestions.
Regards,

Hi,

The fluid that was removed from the space around the lungs is called pleural fluid and that would have been sent for lab analysis.

It should have ideally been sent for pleural fluid - protein, sugar, TLC,DLC, AFB, Malignant cells, ADA, LDH.

Could you post us the reports here?

This would help in reaching a diagnosis about whether this is TB or cancer.

Also, has a CT scan of the chest been advised?

What other symptoms is she having?

For how long has she been on the anti-TB medications? Is she showing any response to these medications?

Let us know about the above details , so that we may be able to help you.

Post us about how she is doing and if you have any other doubts.

Hope this helps.

Regards.
