Worried about vulva cancer

So I have noticed recently my vajayjay has been a but itchy at times but nothing major and just feels different. Anyway today I have taken a mirror to look and at opening of my vajayjay there is what looks like a open wound (doesn't feel sore) but it's like a tear or hole. I have notice sometimes when I wipe there us blood and I think it may have come from that. There is also what looks like a lighter bit of thicker flesh on the right side of the opening and seems fatter. Anyone else had anything similar? I am 31 and married for 7 years so definitely not an STI.
