Hi, I'm 17 and i found a small fatty like lump that i can easily move a couple weeks ago. at the time when i found it i didnt think that much because it was just a week before my period was due and i am a hyprocondriact. My period came lst the week but the lump didnt leave and its been a week since. I'm terrified to tell my mum cause i dont want her to worry, my sister had cancer (not breast cancer) as a kid and my friends mum just passed because of it. Im terrified . we are going on a family holiday next week and i dont know if i should tell my mum and dad or wait til we come back, but im scared it could get worse.
Any help/advice would be appreciated please i'm terrified
