Metastatic breast cancerMetastatic breast cancer, also referred to as metastases, advanced breast cancer, secondary tumors, secondaries or stage IV breast cancer, is a stage of breast cancer where the breast cancer cells have spread to distant sites beyond the axillary lymph nodes. There is no cure for metastatic breast cancer; there is no stage after IV. Metastases can occur several years after the primary breast cancer, although it is sometimes diagnosed at the same time as the primary breast cancer or, rarely, before the primary breast cancer has been diagnosed.
Tumeur du cerveauvignette|Biopsie du cerveau vignette|Scanner du cerveau d'une fillette de 6 ans atteinte d'un médulloblastome (tumeur cérébrale la plus fréquente chez les enfants de moins de 2 ans). Les tumeurs cérébrales désignent l'ensemble des tumeurs, bénignes ou malignes, se développant dans le parenchyme cérébral. Elles surviennent par le développement anormal et désorganisé de divisions cellulaires, à partir soit d'une cellule du cerveau lui-même, soit d'une cellule métastatique exportée d'un cancer situé dans une autre partie du corps.
Cancer du seinLe 'cancer du sein' est un cancer de la glande mammaire. Autrement dit, c'est un cancer qui naît dans les unités cellulaires dont la fonction est de sécréter le lait, les unités ducto-lobulaires du sein, essentiellement chez la femme. Huit cancers du sein sur dix se déclarent après 50 ans. Premier cancer dans le monde, il touche, en 2016, 1,8 million de femmes par an dans le monde, dont en France. On s'attend à ce qu'une femme sur huit reçoive un diagnostic de cancer du sein au cours de sa vie.
Primary tumorA primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass. Most solid cancers develop at their primary site but may then go on to metastasize or spread to other parts of the body. These further tumors are secondary tumors. Most cancers continue to be called after their primary site, as in breast cancer or lung cancer for example, even after they have spread to other parts of the body.
Tumeur neuroendocrinienneLes tumeurs neuroendocriniennes ou tumeurs neuroendocrines (TNE) sont des tumeurs (néoplasmes) qui se forment à partir d'un développement désordonné de cellules du système endocrine (hormonal) et du système nerveux. Ces tumeurs particulières sont le plus souvent bénignes, mais quelques-unes sont malignes et peuvent facilement métastaser. La plupart se forment dans l'intestin et le poumon, mais on en trouve ailleurs dans le corps, sur les organes ayant des fonctions de glandes ou voisin ( pénis, voisin du testicule).
Breast cancer awarenessBreast cancer awareness is an effort to raise awareness and reduce the stigma of breast cancer through education about screening, symptoms, and treatment. Supporters hope that greater knowledge will lead to earlier detection of breast cancer, which is associated with higher long-term survival rates, and that money raised for breast cancer will produce a reliable, permanent cure. Breast cancer advocacy and awareness efforts are a type of health advocacy. Breast cancer advocates raise funds and lobby for better care, more knowledge, and more patient empowerment.
Métastase (médecine)Une métastase (du grec ancien : , de , « je change de place ») est, au sens large, une croissance cellulaire qui se produit à distance du site primaire de cette croissance et sans contact direct avec elle — cette définition inclut en principe les métastases infectieuses ou tumorales, qu’elles s’effectuent par voie hématogène ou lymphatique mais en clinique courante, l’usage du terme est restreint à la métastase cancéreuse.
Cancer of unknown primary originCancer of unknown primary origin (CUP) is a cancer that is determined to be at the metastatic stage at the time of diagnosis, but a primary tumor cannot be identified. A diagnosis of CUP requires a clinical picture consistent with metastatic disease and one or more biopsy results inconsistent with a tumor cancer CUP is found in about 3 to 5% of all people diagnosed with invasive cancer, and carries a poor prognosis in most (80 to 85%) of those circumstances.
Breast cancer screeningBreast cancer screening is the medical screening of asymptomatic, apparently healthy women for breast cancer in an attempt to achieve an earlier diagnosis. The assumption is that early detection will improve outcomes. A number of screening tests have been employed, including clinical and self breast exams, mammography, genetic screening, ultrasound, and magnetic resonance imaging. A clinical or self breast exam involves feeling the breast for lumps or other abnormalities.
Bone tumorA bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. There may be a lump, pain, or neurological signs from pressure. A bone tumor might present with a pathologic fracture. Other symptoms may include fatigue, fever, weight loss, anemia and nausea. Sometimes there are no symptoms and the tumour is found when investigating another problem.
