Please this is from my recent experience with a friend/co worker sister and my not pertain to you. This happen to my friend sister son, but no one noticed it. He is 6 years old now, this was only diagnosed because the sister remarried and move to TX from PR. He son for years was complaining about stomach pain and was a picky eater so they thought, because the doctors in PR said he was fine. Well he was not. The doctor in TX found that because when he was an infant that the umbilical cord did not all come out and the cord did not desolve properly that it cause tumors in his stomach he is going through Cimo now. They said they have very few cases of this. He is doing okay but has a long road ahead of him. So I do not want to alarm you, but I would definitly have it check out really good. They say things happen for a reason and I am a big believer of that. Maybe it was for me to let people know that this can happen.
