Do I have oral cancer I'm just 19

I am Jude Serrao aged 19 , to be honest I used to smoke a lot of cigarettes a day daily and drink alot of alcohol for 1 year . However I quit for some time but then again relapsed but now I'm clean , from 1 years time I'm having reddish like thing on sides of my tongue but also on left side I have a whitesh like patch with small 2 boil like structures and a small vein like structure and when touched it continuously it hurts the vein like structure, it's been for 1 year I had checked it out with 2 local docs , an ent surgeon of 20 years experience he told me it's 100 percent not cancer but the cream he gave didn't work then I went to an oncologist of 20 years experience and he told me to check out with dentist as he might suggest it is because I have sharp teeth which is actually a fact but honestly it's lasted this long is really concerning and I fear I might have tongue cancer 😭😭😭😭 please anyone is there hope
