I'm 21, and for the last year I have been trying to get a diagnosis to why my lymph nodes were swollen and it's difficult to swallow - they found clusters of swollen lymph nodes all over my head and neck through an ultrasound, bloods came back normal, they said it was nothing. 

Then they had me in for a second ultrasound and found "a mass of tissue" coming up to my thymax, so sent me for an MRI.

They found a tumour that was around 3 or 4 times the size of my oesophagus, and the doctor told me he doesn't know what it is and that it needs to be removed through surgery and tested for cancer. 

I also smoked for about 6 years.

I'm so scared - I'm trying so hard to hold it together because I have OCD so I obsess over things - I just keep telling myself it's out of my control. 

Has anyone else been through something similar? I haven't had my HPV vaccine, because my mother refused to sign the consent form when we were all getting it in highschool, and I also had trichomaniasis for a whole year - ended up treating it myself after being passed from gynecologist to gynecologist.
