I have been having pain in my left breast & think I have felt bumps before. What are other symptoms?

I found a lump on my left breast but i’m not sure if it’s cancer (i hope it’s not)….but i’m making an appointment with the doctor to get it checked out. It doesn’t hurt or anything. This lump looks like a bruise & it keeps getting darker. I also found a long strand of blonde hair near the area. I’m not blonde but this made me scared :/ Are there any other things i should look out for?

I already asked this question before but didn’t get enough answers.

Peace xx

-Sore throat since sunday
-Coughing
-difficulty breathing

Symptoms started after I enjoyed a black & mild (cigar)

I’m 18 and smoke them every so often(once a month)

never felt this terrible before though

Hello folks.
I am a15 years old female and I have recently discovered a small lump in my left breast ( about the size and shape of a M&M). I’m especially concerned about it because my grandmother lost her breast to cancer, which means it is in my genes. Is is possible for someone so young like me to develop breast cancer ? Is there certain symptoms (occasional pain in the location, drowsey… etc)…

This is for a research essay. Please & thanks.
If u have any good sites please post them too.
