Breast Cancer - early stage

What is Early Stage Breast Cancer?
A disease of either the milk-producing glands known as lobules, or milk ducts, or other cells found in the breast. Early stage breast cancer may also affect the lymph nodes, but has not usually spread to other areas of the body. Breast cancer is the most common type of cancer diagnosed in women, but may rarely affect men as well. Breast cancer cells may have increased expression of estrogen receptors (ER positive or negative), progestin receptors (PR positive or negative), and/or HER-2 receptors (HER-2 positive or negative). The presence or lack of these receptors will help determine the most effective chemotherapy medications to give.

Genetic causes, such as the BRCA (pronounced "Bracka") mutation, significantly increase the risk of developing breast cancer. Other risk factors for breast cancer include family history of breast cancer, high fat diet, and obesity. The stage of breast cancer can vary at diagnosis and throughout treatment. Stages of breast cancer include I, II, III, and IV. The effectiveness of the treatment may depend upon the stage at diagnosis.

Types of breast cancer:
1. Hormone-receptor positive or negative (60 - 65% of patients)

2. Hormone Epidermal growth factor Receptor-2 (HER-2) positive or negative (20 - 25% of patients)

3. Triple Negative (15 - 18% of patients)
