I have an abnormal mass like a tumor in the back left to my lower vertebrae near kidney area for last 6 months .what should i do and consult doctor or you need some surgery?

I'm not a medical professional, and I cannot give you medical advice. If you have an abnormal mass, you should consult a doctor right away. A doctor can evaluate the mass and determine the best course of treatment. The doctor may recommend imaging tests, such as an MRI or CT scan, to get a better look at the mass. They may also recommend a biopsy, in which a small sample of the mass is removed and tested in a laboratory. It's important to consult a medical professional as soon as possible, as any abnormal growth should be assessed by a qualified doctor to determine the appropriate treatment.
