I suspect hemorroids. A form of cancer?

About a week ago I had a car accident. No injuries but an hour after that i started feeling some discomfort and slight pain at my anus. Ive been feeling the same pain and discomfort for a week. Today I finally decided to take a picture of my anus, very weird. I know. After examining the picture I found a small lump around the size of a pea 2 mm away from my anus. Its is firm yet soft. I googled it and it is most likely hemorroids. I did not see any blood or pain in passing wastes. Just dicomfort and very small pain when sitting or shifting. I dont know if its related but I am always more hotter or warmer than my family and constsntly have the AC on, could it be stress or releated to this? My real concern is, is it a form of cancer? I am by nature shy and I dont want to tell my family or see a doctor whos gonna see my anus. I will happily provide a picture if you are a real doctor or have experience. What could it be and what are the treatment. Thanks.
