Hi guys I have this lump on my finger for a year now what is it

David, without lookin' at it, we couldn't tell you. You got to give us more info dude!

What finger?
What hand? Right or left?
Are you right or left handed?
Does it hurt?

Etc
Etc...

A wart

A knuckle. I have several of 'em. Seem to come in handy now & again.

Of all the posts J9 is the best advice, and the only helpful advice.

OP, why haven't you seen a doctor about this? Maybe it's time to make an appointment, there's very little chance that you'll get an accurate diagnosis over the internet.

Good Luck.

It's a wart dude. Or you just are growing a third nipple but I don't think that's happening.

Sorry--just having a little fun. David, just go have it checked & move on to something more important. Modern medicine has made leaps into quick fixes. I had several facial moles removed in a single visit. It was not expensive, painful, did not bleed and took 30 minutes. Or less. They numb the area, and with a tiny little circular tool remove the growth. Required no medication for infection and went home with a cute little band-aid patch--no stitches. The third day I removed the band-aid and went on with my life. No fear of cancer (they tested them all), and no scars on my face. I could wash the area in comfort.
