p.s. I just noticed from your profile that you are a teenager. If you only meant that someone was biting your boobs during sexual activity, that won't cause cancer either.
Touching, squeezing, sucking, and even (gentle) biting of the breasts is very common during sexual activity. Many people find these forms of stimulation pleasurable, but always know that you have the right to decide which activities you wish to allow and which ones you don't.

Hi Kavin,
You are a smart kid to seek information when you need it!
No, people do not get breast cancer from having their "boobs" bitten, or from other injuries than may occur to the breasts.
At the worst, it might cause an infection if you were bitten to the point of the skin being broken, bleeding, or obvious injury.
If there is no injury, you'll be just fine.
If there is a minor injury,clean the area with soap and water, and then apply a thin film of antibiotic ointment and a band-aid, or just a band-aid, according to what an adult, such as a parent, thinks would be best. If there is a little pain or swelling, using an ice pack for about 10 minutes at a time may help you feel better. But if the area later becomes warm, red, more swollen and oozes white discharge, you should see a doctor, who might prescribe an antibiotic medication.
If you got a serious injury (for example during a fight) you should see a doctor right away, to find out if you need stitches or a tetanus shot.
Many years ago I got a breast bite which tore the skin and bled, while trying to break up a dog fight, but everything turned out fine.
I hope the same will be true in your case. If you get a chance, came back and tell me how you're doing, okay?
Best wishes,
