Some breast cancer cells need estrogen andor progesterone (hormones produced in the body) to grow. These cancer cells have special proteins inside, called hormone receptors. These cells become immortal and divide indefinitely, giving rise to a tumor. There are a range of forms of breast cancer, which differ in where they originate and their severity. Often a cancer will present as a breast lump, and the characteristics of the lump help define the type of breast cancer, and guide future treatment strategies. Cancer stem cells in breast tumors were first discovered in 2003. Some have suggested that normal cells undergo mutations that result in their transformation into bcscs, while others believe that these cells come from the misplacement of somatic stem cells de novo. Cancer cells differ from normal cells in the body in many ways. Normal cells become cancerous when a series of mutations leads the cell to continue to grow and divide out of control, and, in a way, a cancer cell is a cell that has achieved a sort of immortality. While there are different types of cancer cells as there are cancers, they all share a number of characteristics. Characteristics of cancer cells breast cancer invades normal tissues,for new centers of growth. Cancer stem cells (cscs), a subgroup of cancer cells, are considered to have features of stem cells such as self-renewal ability and pluripotent differentiation into other types of mature cells. This study showed that nrg1 treatment induced csc characteristics in breast cancer cell lines. Discrimination of the breast cancer cell lines characteristic by gc-ms analysis. The vocs associated with breast cell metabolism have been analyzed with gc-ms by comparing culture medium headspace of six breast cell lines with medium without cells (fig.). Breast cancer stem cells expressing different stem cell markers exhibit distinct biological characteristics.

The stroma is crucial for the blood supply for cancer cells but it has no role in differentiation in between beningn cancer and malignant cancer cells. The stromal tissue however determines the consistency of the cancer. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, fluid coming from the nipple, a newly-inverted nipple, or a red or scaly patch of skin. In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or yellow skin. The purpose of this study is to perform bioinformatics analysis.
