Is this penile cancer or some form of Thrombotic Lymph node/Vein?

So, I have this lump in my penis that has been present for about a week. It’s very noticeable when it is erect as in the picture. I’m extremely worried this might be some form of malignancy. I’ll be going to a doctor very soon regardless.Age: 24.

Sexual partners: 1 all my life and clear of STD’s

How frequent and for how long do you masturbate?

it looks like a vain just under the skin

It is likely a benign penile varicose vein. I don’t believe it to be thrombosis.
