Granular Pharyngitis. There's no cancer?

I have chronic pharyngitis since 3 months. I met an ENT specialist who told me that it's due to acid reflux due to my schedule and habit of tea and also due to smoking cessation (3 months ago). I am very scared of cancer as I am just 25 and smoked for 3 years. My doctor told me there is no sign of cancer in my laryngoscope but there was just dilated vessels and also I feel like there is a lump in throat while swallowing salive but not problem in eating. Also some post nasal drip. I was prescribed neksium for a month then pan D now. I also met another Ent specialist for second thought. Both of them told me same thing n assured me that in cancer there is weight loss and continuous pain in one place which is not in my case and I even have pain in neck at different points which doc said is due to pain in veins  due to Reflux so 2nd Ent doc prescribed me anti anxiety medicines as he thinks I am civil services aspirant. Can I be sure that there's no cancer? kindly help i am very stressed.😔
