During the four years of post-graduate training, residents learn about clinical oncology, the physics and biology of ionizing radiation, and the treatment of cancer patients with radiation. After completion of this training, a radiation oncologist may undergo certification by the American Board of Radiology (ABR). Board certification includes ...

Stage 0 can also mean no remaining cancer after preoperative treatment in some cancers (e.g. colorectal cancer). Stage I: cancers are localized to one part of the body. Stage I cancer can be surgically removed if small enough. Stage II: cancers are locally advanced. Stage II cancer can be treated by chemotherapy, radiation, or surgery.
The rate of cancer recurrence is determined by many factors, including age, sex, cancer type, treatment duration, stage of advancement, grade of original tumor, and cancer-specific risk factors. [2] [3] [4] If recurrent cancer has already moved to other body parts or has developed chemo-resistance then it may be more aggressive than original ...
Radiation enteropathy represents the longer-term, chronic effects that may be found after a latent period most commonly of 6 months to 3 years after the end of treatment. In some cases, it does not become a problem for 20–30 years after successful curative therapy.
The amount of radiation used in photon radiation therapy is measured in grays (Gy), and varies depending on the type and stage of cancer being treated. For curative cases, the typical dose for a solid epithelial tumor ranges from 60 to 80 Gy, while lymphomas are treated with 20 to 40 Gy.
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.

Terminal patients have options for disease management after diagnosis. Examples include caregiving, continued treatment, palliative and hospice care, and physician-assisted suicide. Decisions regarding management are made by the patient and their family, although medical professionals may offer recommendations of services available to terminal ...
