Not necessarily but it is something that the doctor should examine at your earliest opportunity.
sounds like your pregnant...
let me have a feel an I'll refer you to a doctor?
It is usually found at the anterior part of the breast. (mostly)
If you are referring to abnormal bumps on the breasts, it can be anything from a fatty cyst, to a sign of breast cancer, so it may be important to go for a mammogram. If you are thinking of the bumps on the areola (surrounding the nipple), they are actually raised "sebaceous glands", which provide lubrication during breastfeeding in females.
You need to be more specific, you mean bumps on top (dermal) which would be a type of skin condition or lumps internally that you can feel. Rephrase and someone can help you.
You should have them checked by a doctor.
Usually Breast cancer is internal and is found as a lump or tumor. However there are other types of breastcancer that appear on the outside of the breast, like inflammatory BC. Also if the skin on the breast looks like an orange peel or little bumps, it should be checked.
you need to stand in front of a mirror and look at your breasts. you feel for any unusual changes or bumps, and look for an unusual difference in the breast. it could get confusing if you are still growing breasts, and young women are usually not affected by breast cancer anyway. for more info, take a look at http://www.nzgirl.co.nz/articles/1920.

No, men can have breast cancer too.
If you have hard balls at the end of your breast, they are growing. If there are little bumps that are hard it's breast cancer and if they are just hard in genral they are getting ready/are to produce milk.
