[|Human|] Hi - I ve just noticed a lump the size of a small grape under the armpit of my 5 month old baby girl. I m going to take her to the GP tomorrow morning but i worry he may just say its nothing, so may take her to the hospital too - do you know what this could be? Thank you
[|AI|]  Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query lump on your children armpit could be due to three major reasons. First it could be due to infection which is leading to Arteriovenous malformation. Secondly it could be due to accumulation of fatty tissue, and thirdly it could be due to cyst or certain systemic involvement. I would suggest you to take your child to hospital and get Doppler screening and certain other tests done to find out exact cause of lesions. You should start treatment after proper diagnosis. Maintain cleanness of that area. Keep area Chat Doctor. Hope your concern has been resolved. Get Well Soon. Best Wishes,
