Hello LizFromCanada,
Welcome to the OCF Forums.
Sorry you have had a rough go for the past year and are in the midst of a possible cancer scare. Glad that you are getting things checked out and doing your due dilligence!
1st bit of wisdom I'll echo from the veterans around here when I was following the forums after having a potentially precancerous lesion biopsied from my tongue: "it's not cancer until it's cancer...." that is until you get the biopsy results back do as best you can not to be worried sick...
Finding good coping mechanisms and stress outlets to take your mind off things, is good regardless of what turns out.
Pathology reports routinely take up to a couple weeks. Sometimes they have specific dyes and procedures that require multiple sequential steps just to get the microscope slides prepped.
Same type of delays are likely for scheduling surgery, God forbid, that it does turn out to be cancer.
Is it possible the dark spot that appeared after the biopsy was at the location where they injected the lidocaine numbing agent?
Was it the gum lesion that was biopsied?
Did they end up doing biopsy on the peritonsilar abcess? Was it tested for
HPV?
Your lymph nodes are central to your lymphatic system and the lymph fluid based immune cells. That said any kind of infection, Bacterial, Viral, Fungal, etc... can trigger the lymph nodes in that area of the body to be reactive.
Try to let the past be the past and move on.
With regard to your overall oral health, especially after a possible cancer scare, keep in mind what things you can do to reduce your risk of developing cancer, or recurrences of cancer later.
Not sure of what evidence there is with marijuana smoke and oral health, but pretty good evidence all forms of tobacco are uneccesary risk factors for developing cancer.
Last bit of encrouagement, even if it is cancer, they are developing new treatments a lot these days.
Keep your chin up and hope for the best!
