I feel hurts under my arm because of a tumor. I once had on my leg, but it disappeared in a week. I don't know whether I should go to doctor. I am afraid of surgery. I think it might not be very serious.

Who told you that you have a tumor? How old are you?

If you really had a tumor it will not disappear in a week,

How do you know you have a tumor, has a doctor told you??

Nobody told me that, I guess I have a tumor. That is why I asked whether I should go to doctor

If you have some medical condition you are unsure about, it never hurts to get a physcial exam.

If you don't think it's serious, then why did you post the question?
Its probably just a cyst or, with it being under your arm, a swollen gland. It may not be serious, but you probably should go to your doctor, just to be sure. A tumor would not have gone away on its own. I'm afraid of surgery, but I went through it last year. Had all four wisdom teeth cut out. It isn't as bad as you think it is.

Thank you all. I just tell myself it is not serious because this is what I hope. But it is red and hurts much. I once had a surgery on my legs, and I know how suffering I was. I am afraid that I have bad luck again.

I will go to see doctor tomorrow.

Thank you!

If only for the peace of mind, go to the doctor.

Actually, I think I am lucky for what I have experienced. Once disease occupies some time of someone's life, she has to focus on learning to be strong. Looking back on the elapsed day, I was in hospital when I was at the age in which most of girls were lost by confusion and ignorance. Although I had lots of terrors and pains at that period, I also had wonderful and special memories. I remember I was 17 at that time.
Wish all of you good luck.
