The performance of certain tests is essential for the diagnosis of your disease and for the proposal of the most appropriate therapeutic strategy. CancerConsult provides you with information on health documents related to complementary examinations.
An MRI (or Magnetic Resonance Imaging) is an examination technique that allows information to be taken on organs thanks to a magnetic field and radio frequencies. The patient lies down and enters the cylinder by the feet or the head depending on the area to be analyzed. This examination is painless and may require the injection of a contrast product to improve the quality of the images. Once the MRI is performed, the radiologist recovers the different images to interpret them. MRI can diagnose many tumors.
A CT scan is another examination technique that uses X-rays to provide an overall view of an area of the body. Lying on a table, the C-arm is placed at the level of the area to be examined and rotates around the patient. This examination, which is painless and may require a contrast medium, measures the absorption of X-rays by the tissues and allows the detection of anomalies in the organs. The scanner is also used to monitor the effectiveness of chemotherapy or to assist in a biopsy.
A biopsy consists of taking a piece of organ or tissue with a needle during surgery, an ultrasound scan or an endoscopy. The sample will then be analyzed (pathological examination) to detect the presence of cancerous cells and any molecular abnormalities. Almost all tissues of the human body can be removed. For this examination, the patient is under local or general anesthesia. In oncology, the biopsy is used to establish a diagnosis and possibly prescribe other examinations to refine it.
Molecular profiling is part of precision medicine and allows for the personalization of the patient's therapeutic strategy. The objective of this practice is to know the alteration of the genes that led to the development of the patient's cancer.
The doctor will then analyze the tumor (or a blood sample, called a "liquid biopsy") and will be able to reason about the disease in relation to its stage and location, while taking into account its molecular aspects.
Molecular profiling is not feasible (or useful) in 100% of cancers, and will be proposed on a case-by-case basis.
