Tumor markers can be molecules that are produced in higher amounts by cancer cells than normal cells, but can also be produced by other cells from a reaction with the cancer. [2] The markers can't be used to give patients a diagnosis but can be compared with the result of other tests like biopsy or imaging. [2]
Recurrent cancer is any form of cancer that has returned or recurred when a fraction of primary tumor cells evade the effects of treatment and survive in small spaces that are undetectable by diagnostic tests. The initial tumor may become the site of cancer’s return or it may spread to another part of the body. [1]
Minimal residual disease (MRD), also known as Molecular residual disease, is the name given to small numbers of cancer cells that remain in a person either during or after treatment when the patient is in remission (no symptoms or signs of disease). Sensitive molecular tests are either in development or available to test for MRD.
Oncology is a branch of medicine that deals with the study, treatment, diagnosis, and prevention of cancer. A medical professional who practices oncology is an oncologist . [ 1 ] The name's etymological origin is the Greek word ὄγκος ( ónkos ), meaning "tumor", "volume" or "mass". [ 2 ]
Hematological malignancies are malignant neoplasms ("cancer"), and they are generally treated by specialists in hematology and/or oncology. In some centers "hematology/oncology" is a single subspecialty of internal medicine while in others they are considered separate divisions (there are also surgical and radiation oncologists).
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of ...
The tumor in the lung is then called metastatic breast cancer, not lung cancer. Metastasis is a key element in cancer staging systems such as the TNM staging system, where it represents the "M". In overall stage grouping, metastasis places a cancer in Stage IV. The possibilities of curative treatment are greatly reduced, or often entirely ...
Among these main diagnostic tests, other radiologic tests such as excretory urography, positron-emission tomography (PET) scanning, ultrasonography, arteriography, venography, and bone scanning can also be used to aid in the evaluation of staging renal masses and to differentiate non-malignant tumours from malignant tumours.
