After a lumpectomy is performed for DCIS, local radiation therapy is typically performed to help eliminate microscopic-level disease. Axillary sentinel lymph node biopsy, as a method of screening for metastatic disease in otherwise non-invasive DCIS, is falling out of favor because the risks of procedure outweigh any effect on outcomes.

Targeted intra-operative radiotherapy, also known as targeted IORT, is a technique of giving radiotherapy to the tissues surrounding a cancer after its surgical removal, a form of intraoperative radiation therapy. The technique was designed in 1998 at the University College London. [1]
The depth of penetration is very limited, typically either ½ cm to 1 cm depth, sometimes requiring extensive surgery due to the limited penetration of the radiation. Treatments tend to be 40 minutes or longer, resulting in greater OR time, more anesthesia and greater blood loss when compared to electron IORT.
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.
Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
Exactly why PAH happens after CoolSculpting treatments is unclear, and more research is needed to assess whether PAH may be due to the technique of the procedure, type of machine used or even a ...
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.

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 ...
