Yes, Crysilla, any lump in the breast might be cancer. However, in someone your age the lump is more likely to be a non-cancerous lump called a fibroadenoma or a cyst. Painful lumps are often harmless cysts. Sometimes a painful lump is an abscess--a type of infection. You can't tell for sure though which type you have. Only a doctor can rule out cancer and tell you what this is. So it is way too early to panic. Unless you have a mother, sister, or grandmother who had breast cancer, the other members of your family with cancer don't increase your chances of having breast cancer. It is time to be assertive about your health and get that lump checked out. Let us know what you find out.
