You could see changes in Chutki as minor has loss of appetite and lethargy, to more obvious signs such as vomiting. A biopsy will need to be done to determine if it's malignant or benign. A blood test will not tell this. If it's malignant, no an antibiotic will not cure it. If you are very concerned about this, have her spayed. That will remove the ovary completely.
