Getting informed well about sicknesses?? It helps OR creates more health anxiety for you?

Sorry for the long text.
WARNING: some Symptoms and causes are listed down below. If you are sensitive and getting anxious by reading these stuff, you may pass this post :) I am sorry for the trouble I cause <3

Last night my husband made a small research for me saying "obviously you are making things up in your mind based on rootless info you got before all your life, and I am sad to see you suffer and get panic because of these ridiculous thoughts..." :/ Well I sort of forced him to search also, thinking I may find something that will ease my mind.
So he opened up his sparkling search engine (he refuses to use Google and he is a programmer. He says he doesn't like the way Google bases search results on) and started searching about the questions I made.

I told him before that maybe knowing better about the sickness I am scared of, perhaps, may help with avoiding irrational thoughts. So I wrote down (about my current worry);

- What is oral cancer? How does it look like? Anything close to the stuff I am getting in my mouth?
(He searched some pictures first but I refused to see them because I am too sensitive with this stuff) He said those things he saw in pictures were no where close to the thing I have in my mouth. There was only one pic close to the texture I have but it was yellow instead, he said.

- What are causes? How does it develop/stages? Biting and peeling inside of the mouth/lips can cause it? (this last question was the info I got whole my life from different people and on internet, so I am very scared because I am messing with the inside of my cheek for a while now = my worry/panic).
He said he found in results that Oral cancers are 75% because of smoking and alcohol use. Remaining were listed as; A specific virus type, history of oral cancer, genes and very bad mouth hygiene. Biting/peeling wasn't listed (in different sources). Some of the mouth abnormalities can be diagnosed as pre-cancerous, which MAY turn in to oral cancer. There is a treatment for them also, in order not to let them turn into something dangerous. (I don't smoke and drink alcohol...)

- Is oral cancer a rare type of cancer?
He found out that by a research made in UK, around 6200 people in UK get diagnosed with this condition every year. UK has a population of around 64 mil people. which makes it rare, I guess? Well, I am grade 1 at maths xD

Is oral cancer treatable? How likely it is to get successful results?
It has a treatment, like every cancer type. He read that success depends on the age of the person. Around my age (38) he said, it is 70% chance of getting it successfully treated. Also it depends on where in the mouth the cancer developed (tongue, gum, cheeks, etc) and stage of it.

So after reading all of these, he asked me if I feel a bit more convinced and if I feel a bit better now.
Yes, I feel myself better now to be honest. Since my theory was based on biting/peeling inside the cheeks. We didn't manage to find proper info about that really.
My husband came to the conclusion that the info I got before, was most likely a research based info. But still in medical literature since it counted as a cause for oral cancers. Like any other symptom also it may be shared by millions of conditions. Like a headache...

That's all...

Yes I have an appointment, on Tuesday. But I mean, I guess finding out some realistic possibilities helps me actually think more logical.
For example, a mild headache is not a panic reason for me because I was told by doctors/psychiatrist many times that a headache which comes and goes and can easily be distracted by other things, doesn't refer to something dangerous. So my point is, this is a correct information told by a dr.

So I made this post to see how it works for you.

Yeah you are very right :)
I thought first "maybe there is something wrong with google" lol xD
Supportive people in our case is important to overcome this disorder.
It will turn out good <3
