I have this hard bump on my leg near my nether regions! I'm worried!!! Should I be?

Cancer runs in my family so I am like seriously worried. If you have any advice if like it. The bump is like 2 cm and feels kind of hard. This will sound weird but when I squeezed it puss came out but when I tried again it didn't! !!! Help me! (p.s keeping this anonymous causey sis can see it too)
