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.

The radiation which is produced by low-energy mobile radiation systems has a limited range. For this reason, conventional walls are regarded sufficient to stop the radiation scatter produced in the operating room and no extra measures for radiation protection are necessary. This makes IORT accessible for more hospitals.
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.
Surgical removal, with or without additional radiation therapy or tamoxifen, is the recommended treatment for DCIS by the National Cancer Institute. [29] Surgery may be either a breast-conserving lumpectomy or a mastectomy (complete or partial removal of the affected breast). [30] If a lumpectomy is used it is often combined with radiation ...
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.

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 ...
Absolute contraindications, which are reasons why the procedure absolutely cannot be done, include: [9] Pregnancy is an absolute contraindication to the use of breast irradiation. In some cases, it may be possible to perform breast-conserving surgery in the third trimester and treat the patient with radiation after delivery.
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 ...
