I had a lymph node swell in my neck in Sept of 2019. I went to the doctor a week later for a regular wellness checkup. When I told him of it and he looked at it he decided to give me a strong round of antibiotics saying it could just be an infection. He instructed me to let him know if it did not fully go away and if it didn't he would order a CT scan. It did not go FULLY away so I told him and I had a CT scan. The results of the CT scan said it was worrisome of or something like that of squamous cell carcinoma. I knew if they actually named the cancer it resembled it was probably cancer. They ordered a biopsy and it was what they suspected. Turns out it started in my Tonsil and spread to my a lymph node in my neck. Luckily it swelled up quickly which gave us an early diagnosis as I was Stage 1 / 2 when diagnosed. It did however grow from 1cm to 5cm in length 3 months but was down to the size of my thumbnail in just 10 radiation treatments. I went on to have 25 more rounds of radiation which was the worst and maybe the best thing at the same time. I also had 3 rounds of Chemo which had its own side effects. I finished my treatment in Feb of 2020 and I am cancer free today. I hope yours is not cancer and they resolve it what ever it is. Good luck and Gods Speed.
