If I accidentally injecting human breast cancer cell lines into my finger - What happens? (Oct/25/2006 )
What happens if I accidentally injecting human breast cancer cell lines into my finger?
Do I get breast cancer? 
not unless you're an immuno compromised mouse... are you?
If you have a normal healthy human immune system, it will distinguish foreign tissues and attempt to destroy them, just as it attempts to destroy infective organisms such as bacteria.
You'll be fine.

Do I get breast cancer?
Of cause you dont want to mess up with that first. If it happens you need to seek medical help. Our univeristy has a work-related injury claim clinic. This should be treated as an accident and reported to OSHA. Many cancer cell lines may carry viral components and are certainly biohazard materials. On the other token, unless it is very unlucky such that the cell line shares perfect matching blood types with you, the chance for you to get breast cancer would be like getting a sucessfully transplant without using large doses of immune suppressant.
agree with Vetticus and genehunter.
You have to announce the accident to the adequate MD, but you don't have to worry. Your immune system has to kill the foreign cells.
Agree with others.
Also u should inform ur PI and get medical help immediately.
Thanks you everyone.
I think I will be fine, because I am a healthy non-immunocompromised wild-type Minnie Mouse

I have a friend how injected accidentally cancer cells (I don't know if i remember right but I think they were HeLa cells ot a strain from them), he get a big wart on the finger. After removing nothing else happed (until now 
). Perhaps only papillomavirus infection, these cells are related to Hela cells, anyhow I don't know.
HeLa have HPV DNA in them (no surprises there, most cervical cancers are HPV related). I am guessing that the actual HeLa cells were killed, but the wart was the result of the latent HPV present in the cells.
