Yellow-Orange Fluid Drained From a Cyst

Clear yellow to orange fluid is common in fluid-filled cysts, such as sweat gland (apocrine) cysts, and in seromas, which are pockets of fluid under the skin. An orange or darker color can also come from old blood inside the lump. Most of these are harmless, but the color alone can't tell anyone for sure.

It's fair to ask your vet what the $300 covers. Looking at the fluid and any cells under a microscope (cytology) is often less expensive than a full pathology work-up and may be enough to show the lump is a simple cyst. If the lump is removed later, sending the whole thing for a biopsy gives the most definite answer.

If the lump fills up again, removing the whole cyst, including its lining, usually stops it for good. Have it checked sooner if it grows quickly, becomes hot or painful, or the fluid turns cloudy or bloody. If cost is a worry, ask your vet about a payment plan, or look for a low-cost clinic, humane society clinic or veterinary school near you.
