Did this happen to you? When you sat in your chair and felt relaxed on your Saturday morning, nothing particularly got in your mind and one of your hands might unconsciously move around. But suddenly, you felt that there was something wrong. Your hand touched your neck by accident, and under your fingers, there was a node just as small as a bean. It drew all your attention immediately and your heart seemed brought up to your throat. You used your index finger pulp carefully press on the right of your neck, then with your middle finger. Both fingers released to you the same information that it was there, a small soft bean-like alien setting under the skin of your right neck. You couldn’t wait to touch the left side of your neck, but it was unusually smooth. You were overwhelmed by your discovery，“Is that a sign of cancer? Am I dying?” Looking around your room and your toddle daughter who was playing in the corner, you felt that your tears had already filled in your eyes. Life is pretty good and you just start it after years of efforts. You thought of your loved partner and your parents, what would be for them if you died? And the process of dying though was scary! All kinds of thoughts occupied your mind, and now sitting in your chair you were petrified. It seemed nothing you could do but wait to be sentenced when you went to see a doctor.
