Cancer on Rooster's Comb???

[Rose66]

My frizzle rooster has a large hard knot on the back end of his comb that I wonder if it is cancer. Below are pics of it. Do y'all think it needs to be removed? It doesn't seem to bother him. Thanks!

I am thinking that may be infection from an injury or severe peck wound, but not sure. Tumors and cysts can be very common in chickens, but I don’t recall seeing them on combs. I am going to tag a few experienced members who may have seen something like this:
@dawg53, @sourland, @roosterhavoc, @azygous, @TwoCrows , @casportpony ?
I would be tempted to clean it up with either betadine (Equate Antiseptic Wound Solution) or chlorhexidene (Hibiclens) and water, and see if there is puss inside the wound.

Is his earlobe the same color on both sides, and is that normally the color?

I have not seen anything like that on a comb either, but I would also be tempted to clean it and pick at it.

It could be an infected wound. It could be an infestation of scaly mites, or it could be cancer.

As @Eggcessive has suggested, I would see if it responds to treatment as a wound first of all. If it's an infected injury, hydrogen peroxide should fizz like crazy on it. Try squeezing the wound to eject any pus and necrotic tissue, flush well with saline or soapy water, then put antibiotic ointment on it.

If it appears to end up looking like a tumor, the comb is the easiest place on a chicken to remove undesired ruined tissue. Simply cut it away with sharp scissors. Be prepared with corn starch to staunch the bleeding, and then dress with ointment and Vetericyn until it heals over.

I’ve never seen that before either. If that was my rooster I would cut off the damaged tissue from under the damaged part in one straight line to the valley of the first comb point.

To me it looks like necrotic tissue. You might be able to clean it out by softening with antibiotic ointment and gradually removing. I would be tempted to remove that portion of the comb - realizing that it will bleed significantly. Cauterize if possible or apply silver nitrate or some other clotting agent. Have his earlobes always been that color ?

Thanks to everyone for all the help. We will clean it up and pick at it to see if it is an infection of some kind and if we do not find any indication of an wound, then we will remove that portion of his comb. Yes, both of his ear lobes have always been that white'ish color. I will post back on what I find and/or do. Again, thanks for the help!
