What is a branchial cyst?
A branchial cyst is almost always a benign (non-cancerous) lump in the neck. It can become enlarged quickly, especially if you have an illness like the flu. If it gets infected, the cyst may need to be treated with antibiotics, or if it doesn’t go away, or keeps coming back, you may need surgery to remove it.
