Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
High-dose chemotherapy and bone marrow transplant (HDC/BMT), also high-dose chemotherapy with autologous bone marrow transplant (HDC/ABMT or just ABMT), was an ineffective treatment regimen for metastatic breast cancer, and later high-risk breast cancer, that was considered promising during the 1980s and 1990s.
Medical research for cancer begins much like research for any disease. In organized studies of new treatments for cancer, the pre-clinical development of drugs, devices, and techniques begins in laboratories, either with isolated cells or in small animals, most commonly rats or mice. In other cases, the proposed treatment for cancer is already ...
Metastatic breast cancer to the lung or pleura causes chronic cough, dyspnea, abnormal chest X-ray, and chest pain. Other nonspecific systemic symptoms of metastatic breast cancer include fatigue, malaise, weight loss, and poor appetite. Sometimes people with metastatic breast cancer do not have any notable changes or symptoms. [8]
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib.

A liver metastasis is a malignant tumor in the liver that has spread from another organ affected by cancer. The liver is a common site for metastatic disease because of its rich, dual blood supply (the liver receives blood via the hepatic artery and portal vein). Metastatic tumors in the liver are 20 times more common than primary tumors.
Palliative chemotherapy is used to control (but not cure) the cancer in settings in which the cancer has spread beyond the breast and localized lymph nodes. See metastatic breast cancer. Combined therapies These combine, for example, non-drug treatments with localized chemotherapy to limit toxicity and achieve better results. [3]
