Cancer that has spread to other places in the body.
Blood vessel formation. Tumor angiogenesis is growth of new blood vessels that tumors need to grow, caused by the release of chemicals from the tumor.
Programmed cell death- the normal process in which molecular steps lead to cell death. This is how the body gets rid of unneeded or abnormal cells. The process of apoptosis may be blocked in cancer cells.

The measure of hormone receptors on cancer cells.
Medicines that stop the action or production of hormones
Treatment that adds, blocks, or removes hormones. For certain conditions (such as diabetes or menopause), hormones are given to adjust low hormone levels. To slow or stop the growth of certain cancers (such as prostate and breast cancer), synthetic hormones or other drugs may be given to block the body’s natural hormones. Sometimes surgery is needed to remove the gland that makes a certain hormone. Also called endocrine therapy, hormonal therapy, and hormone therapy.

At this point, the cancer can spread locally in the same breast, to nearby regional nodes, and further beyond the affected breast.
Also a type of cancer but differentiated from and much less common than ductal type. Like ductal type, lobular carcinoma can also form mass and distortion. However, it can also be much more subtle on imaging, and therefore harder to detect.

Spread beyond the breast or nearby lymph nodes to distant areas of the body.
Cancer that has spread beyond the original location to other parts of the body.
A protein made in the laboratory that can locate and bind to substances in the body, including tumor cells. Each monoclonal antibody is made to find one substance. Monoclonal antibodies are being used to treat some types of cancer and are being studied in the treatment of other types.

Cancer patients taking certain bone drugs called bisphosphonates may develop bone damage in the jaw, which disrupts the blood supply to the bone, causing tiny breaks that can eventually lead to bone collapse.
Surgery to remove one or both ovaries.
A substance used to treat moderate to severe pain. Opioids are like opiates, such as morphine and codeine, but are not made from opium. Opioids bind to opioid receptors in the central nervous system. Opioids used to be called narcotics. An opioid is a type of alkaloid.
Osteoblastic/Osteolytic Bone Metastases
Metastatic bone lesions are also known as osteolytic, osteoblastic and mixed, and are most common where the destructive processes outstrip the laying down of new bone. Osteoblastic lesions result from new bone growth stimulated by the tumor.

The quality of an individual’s daily well-being.
A doctor who specializes in treating cancer with radiation.
The use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy). Systemic radiation therapy uses a radioactive substance, such as a radio-labeled monoclonal antibody, that travels in the blood to tissues throughout the body. Also called irradiation and radiotherapy.
A procedure using radio waves to heat and destroy abnormal cells. The radio waves travel through electrodes. Radiofrequency ablation may be used to treat cancer and other conditions.
Radiologist or Breast Imaging Radiologist
The physician imaging specialist who interprets all of the breast imaging studies. These doctors also perform the needle procedures used to biopsy (ultrasound, stereotactic, or MRI guided) and preoperatively localize the problem areas. They are breast imaging specialists who work with the breast surgeons, breast oncologists, and breast radiation therapists in the team approach.
Unwanted effect caused by medicines or treatments, including emotional and physical symptoms.
Cancer that has come back.
Decreases in the tumor size or spread of cancer.
Unwanted effect caused by medicines or treatments, including emotional and physical
Stages of Breast Cancer
These describe the extent of the cancer in the body and are based on whether the cancer is invasive or non-invasive, tumor size, lymph node involvement, and whether or not it has spread to other body parts. Cancer staging is one of the key factors that allow healthcare providers to determine prognosis and treatment.
Performing tests to determine extent of the cancer within the body, especially whether the disease has spread from the original site to other parts of the body. It is important to know the stage of the disease in order to plan the best treatment.
Medicines/treatments that treat the whole body by traveling through the bloodstream.
Treatment that uses drugs or other substances, such as monoclonal antibodies, to identify and attack specific cancer cells. Targeted therapy may have fewer side effects than other types of cancer treatments.
Short breaks in treatment that allow for rest or for special events.

Breast cancer cells that do not have estrogen receptors, progesterone receptors, or large amounts of HER2/neu protein. Also called ER-PR-HER2/neu- and TNBC.
A substance that may be found in tumor tissue or released from a tumor into the blood or other body fluids. A high level of a tumor marker may mean that a certain type of cancer is in the body. Examples of tumor markers include CA 125 (in ovarian cancer), CA 15-3 (in breast cancer), CEA (in ovarian, lung, breast, pancreas, and gastrointestinal tract cancers), and PSA (in prostate cancer).
A substance made by cells that stimulates new blood vessel formation. Also called vascular endothelial growth factor.
