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.

A liver metastasis is a malignant tumor in the liver that has spread from another organ that is 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 liver ...
Metastatic lesions from breast cancer may produce symptoms according to that organ system. The most common sites for metastasis are the bone, lung, liver, and brain. [17] Skin metastases most commonly extend to the skin overlying the mass, but may spread to the axilla or more distant areas. [18]
A major use of systemic radioisotope therapy is in the treatment of bone metastasis from cancer. The radioisotopes travel selectively to areas of damaged bone, and spare normal undamaged bone. Isotopes commonly used in the treatment of bone metastasis are radium-223, [113] strontium-89 and samarium (153 Sm) lexidronam. [114]
Estimates based on most recent data suggest that each year there are 841,000 new liver cancer diagnoses and 782,000 deaths across the globe. [55] Liver cancer is the most common cancer in Egypt, the Gambia, Guinea, Mongolia, Cambodia, and Vietnam. [55] In terms of gender breakdown, globally liver cancer is more common in men than in women. [43 ...
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]
