[|Human|] hi doctor, my dad has had a large lump on his upper right arm for quite long time. I noticed it about two weeks ago and tried to covince him to go  get it checked, but he refuses to go to the doctor. The lump is  painless and theres no discolouration in the area around it, he has also been experiencing fatigue. I am concerned that it could be cancerous! Could it be any thing serious or do you think it might be benign? And does he have to get it checked? I hope you can help  doctor. And maybe I should also mention that I live in a very poor country with very poor medical qualifications. So Im also kind of afraid that the diagnosis here might  be wrong. So please help doctor.
[|AI|]  Hi and thanks for using this forum for your queries.I am sorry about what your dad is experiencing. Lumps are very non-specific. They could be several things. The worst fear is a cancer. It could simply be a lipoma and sounds more like that. From the description, it will be rare for this to be cancerous. However, let a medical personnel take a look and consider all the possible options. Make an appointment and at least hear what they have to say. If the answers re not satisfying, you may want to get a picture, post to me and may be followed up with a discussion for me to say more about this to you. Hope it helps. Wish your dad good health. Feel free to contact me if need be.
