Large cyst like thing on pantyline

About a half hour ago I noticed a large painless bump about an inch from my vulva/on my pantyline/almost on thigh. It's NOT red, inflamed, itchy, or disruptive, but I'm concerned it's dangerous. It's under the skin, but you can see a visible bump. It's quite large and it's almost an inch in diameter. It's not an ingrown hair (I've had them and this is nothing like that) or a standard pimple. Also, it's slightly mobile. I've never gotten a cyst or anything other than a small little bump from shaving in that area before. I'm really scared that it's cancerous!  If it helps:
*I'm a virgin
*I don't have herpes
*I'm 13
*It doesn't have a head

Please help me :(

Hi there!

Well, without a clinical evaluation it would be difficult to determine the cause of your symptoms. Possibilities that may need to be considered include cysts, folliculitis, growths/ masses etc. I would suggest getting this evaluated by a primary care physician or a gynaecologist for an accurate diagnosis and appropriate management.
Hope this is helpful.

Take care!
