Thanks everyone,

My symptoms did not come and go, it is persistent and slowly getting worse. Redness at the back of throat and soft palate, white patches on my tongue, 2 hard lumps on the neck, tonsil enlarged, felt something on the base of tongue.

You are right, I should get a biopsy for confirmation. But I am convinced it is a HPV+ oral cancer, I knew what I have done wrong in the past. At my young age, I was too naive and didn't know much about HPV. If only I am better educated about it, these things will not happen.

My wife never had pap test before and she shows symptoms such as frequent urination, abnormal period, etc.
She also had persistent earache for months.
My daughter frequently clearing her throat, and snoring every night. That's why I am so stressful and feel guilty.
This is all my fault and now have to face the consequences.
My wife and daughter is innocent, I have ruined their life.
I don't know how to tell my wife. she will not accept it. She will never forgive me and she will dump me for sure.
I can only keep myself busy and try not to worry.
We will have a vacation next week. After this, I will plan to get biopsy. I must accept reality.
Felt relieved after expressed my problems in this forum.
Thanks for your support.

Steve
