Mammography: From what age?

In France, so-called "organized" screening is offered to all women aged 50 to 74 years. Every woman receives a mail at home inviting her to perform a mammogram. It is recommended to perform a mammogram every two years: these screenings are free, fully covered by the Health Insurance. From the age of 50, every woman receives a letter from her home inviting her to perform the exam at an approved radiology center. Performing a mammogram with this organized screening is surely the preferred solution, because if a first radiologist does not detect anything in the X-ray analysis, a check by a second radiologist is done. In addition, X-ray equipment used for organized screening must meet strict quality criteria.

In addition to this organized screening, women carry out this screening on an individual basis, and sometimes before the age of 50. Note that the vast majority of experts consider it unnecessary to perform this mammography systematically before age 50. Indeed, at age 40, the breasts are still very dense and very opaque on radiography, and the results are therefore less reliable. Visibility is less.

Before the age of 30, specialists consider that mammography gives only few visible results. In addition, performed on a woman too young, the examination can be dangerous. It is not advisable to irradiate a breast too young, still in full development. That said, these real risks are not proven.


At what age in families at risk?

A high-risk person is a woman with one or more very close relatives (mother, sister) who have developed breast cancer. In fact it depends more precisely on the size of the family, the age of onset of cancer (before age 50 or later), and the number of breast or ovarian cancers that occurred in the family.

Based on these data, an oncogenetic consultation may be advised by the physician, and possibly a blood test for predisposing genes and monitoring by repeated mammograms may be prescribed.

Caution: Mammography does not detect all pathological conditions. Pre-cancerous lesions are only detectable from a certain size. It can also happen, very rarely, that cancers that evolve unfortunately quickly develop between two control mammograms (we speak of cancer interval).

Hip prosthesis: The prosthesis

The hip prosthesis consists of 2 parts: a femoral head and an acetabulum. These parts will replace the defective bone parts of the hip joint. They are made of very strong materials and resistant to wear. They are often kept in place for years (10 years and older). When the hip joint is destroyed as a whole, it is a total hip prosthesis that is put in place

MRI: brain MRI

Brain MRI has made tremendous progress in brain exploration and in the treatment of many neurological diseases. Of course, it may be required to search for a tumor, a brain malformation, aneurysm, thrombosis ... or in front of neurological signs that point to a cerebral pathology. Today, we also use functional brain MRI: it allows to visualize brain functions: to see for example what areas of the brain are active when the memory is used, which ones work when the patient does mental calculation

Hysterectomy: The progress of the operation

Hyestérectomie: the course of the operation. In the vast majority of cases, when there is suspicion of cancer, the surgeon will have to "open". In other words, the surgeon makes an incision a few centimeters down the abdomen. But if there is no suspicion of cancer and the uterus is small, it can pass through the vagina (after laparoscopy).
