Whoa, did not expect a visual.
So, I wouldn't freak out about anything but I'd see the GP and take your pic with you where it would be appropriate to show them, after you have asked them first, of course.
I had, what I thought, was a huge lump and went to the GP because it was hard and immoveable. Textbook for bad things according to the internet.
No blood or any other symptoms apart from it was sore. The GP did a check in the office and then put me on a 2 week pathway for a sigmoidoscopy.
In my case, it was a haemorrhoid, but I would not be taking advice to just do nothing or diagnose yourself.
We don't know what the true diagnostic requirements are without speaking to professionals first so better to be safe than sorry but, again, don't PANIC!
