I am 22 years old and am generally healthy. I have always had a fear of developing cancer. My concern is with my lymph nodes particularly in my groin. I remember the first time i felt them i freaked out, and that was about 5 years ago. I went to the doctor and everything was normal to him. I have let it go and now I am concerned again. A few months back i had a ultrasound done on them. I was sent to the surgeon who said they looked normal except one which was larger than the others. i think he said it was 2cm but i cant remember exactly. He said he could do a biopsy but i shouldn't worry about it, so i left and never got it done. Everytime i get blood work it comes back normal and I'm going again tomorrow. I don't know what else to do, and i cant get rid of this fear. I am always pretty tired i don't know if that relates, and i also had mono maybe 8 or so years ago which again i don't know if it relates or not. Would love some input. Thank you.
