Cancer-Related Dictionary

EU4H, or European Union for Health, refers to the collective health initiatives, policies, and regulations managed by the European Union. It encompasses a diverse range of topics, such as public health, health education, disease prevention, and healthcare services across European nations to foster better health outcomes for its inhabitants.

An echocardiogram is a non-invasive diagnostic test that uses ultrasound waves to create an image of the heart. It allows doctors to see the heart's size, shape, and motion, and evaluate its chambers, valves, and blood flow. This test aids in diagnosing heart diseases and determining treatment courses.

Ectopic ACTH syndrome is a condition where a tumor outside the pituitary gland produces adrenocorticotropic hormone (ACTH), leading to excessive cortisol production and symptoms of Cushing's syndrome.

Electrochemotherapy is a medical treatment that combines chemotherapy and electrical pulses to enhance the effectiveness of anti-cancer drugs, primarily used for treating skin and subcutaneous tumors.

Endometrial stromal sarcoma is a rare type of cancer that originates in the connective tissue cells of the endometrium, which is the lining of the uterus. It is characterized by abnormal and uncontrolled growth of these cells, which can invade surrounding tissues and spread to other parts of the body.

Endometrial cancer is a type of cancer that starts in the inner lining of the uterus, known as the endometrium. It is the most common form of uterine cancer and is typically diagnosed in postmenopausal women. Symptoms may include abnormal vaginal bleeding, pelvic pain, and pain during intercourse. Early detection is crucial for successful treatment.

An endoscope is a medical instrument used for visual examination of internal body structures that are not visible to the naked eye. It comprises a flexible or rigid tube fitted with lens systems and a light source, allowing doctors to diagnose, monitor and surgically treat various conditions. It's regularly used to examine organs such as the stomach, colon, or lungs.

Eosinophil is a type of white blood cell that plays a crucial role in the immune system. These cells are created in the bone marrow and can be found in the bloodstream and gut lining. Eosinophils are known for combating parasites and controlling mechanisms associated with allergy and asthma. An increase in eosinophils, known as eosinophilia, often indicates a parasitic infection or an allergic reaction.

Epidermal carcinoma is a type of skin cancer that originates in the epidermis, the outermost layer of the skin. It involves the uncontrolled growth of abnormal cells in this layer, leading to the formation of tumors. This condition is often associated with prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds.

Epidermoid carcinoma, also known as squamous cell carcinoma, is a type of cancer that primarily originates from the squamous cells found in the skin or the mucous membranes. It's commonly seen on sun-exposed areas like face and hands but can occur in other body parts. It often appears as a scaly, crusty, or warty growth or a non-healing sore. Regular medical checkups are essential for early detection and treatment.

Epithelial cells are a type of cell that lines the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. They serve as a barrier between the inside and outside of your body and have specialized functions including secretion, selective absorption, protection, transcellular transport and detection of sensation.

An erythrocyte, also known as a red blood cell, plays a fundamental role in the body's circulatory system by transporting oxygen from the lungs to body tissues. These biconcave-shaped cells, packed with hemoglobin, allow them to bind with and carry oxygen and carbon dioxide. They lack nuclei, making more room for hemoglobin. Erythrocytes, a vital component of blood, give it a characteristic red color.

Esophageal cancer is a type of malignancy that originates in the esophagus, the long, hollow tube that connects your throat to your stomach. It generally starts in the cells lining the esophagus and can occur anywhere along the esophagus. The disease is often symptomatic with difficulty swallowing, weight loss, or chest discomfort. The two primary types are squamous cell carcinoma and adenocarcinoma.

The estrogen receptor (ER) is a protein within cells that binds to the estrogen hormone. There are two types: ER-alpha and ER-beta. Upon binding, these receptors can alter gene expression, influencing cell growth and differentiation. They play significant roles in reproductive and non-reproductive systems, and can be involved in certain diseases, including breast cancer.

The "Europe Beating Cancer Plan" is a strategic initiative by the European Union aiming to facilitate cooperation among Member States, optimizing resources to effectively prevent, diagnose, and treat cancer. It accentuates the importance of research, quality of care, innovation, and reducing inequalities in tackling cancer across the region.

An excisional biopsy is a medical procedure where an entire lump or suspicious area is removed for diagnostic examination, primarily to rule out or confirm cancer. It is often performed under local anesthesia. The excised tissue is then analyzed by a pathologist for signs of disease.

Exon is a segment of a DNA or RNA molecule containing information coding for a protein or peptide sequence. It is essential for genetic expression, in which these coded sequences are translated to enable protein synthesis. Exons can also be referred to as "coding sequences" as they are transcribed into mRNA.

"Extramedullary" refers to the process or occurrence happening outside the bone marrow. It typically pertains to the production of blood cells in locations other than the bone marrow, a process known as extramedullary hematopoiesis. It may indicate certain medical conditions including anemia, leukemia, or myelofibrosis.

Extranodal lymphoma is a type of cancer that originates in lymphocytes, a kind of white blood cell, but occurs outside the lymph nodes. It can affect organs such as the stomach, skin, and brain.

Extrathyroidal extension refers to the spread of thyroid cancer beyond the thyroid gland into surrounding tissues. This can affect treatment options and prognosis.

Extrinsic apoptosis is a process where cells are programmed to die as a way to control cell growth and maintain balance in the body. This process is triggered by external signals that activate death receptors on the cell surface, leading to a series of events that result in cell death.

Eyelid cancer refers to a variety of malignancies that affect the eyelid. These are usually skin cancers, which develop from cells lining the eyelid. Its common types include basal cell carcinoma, squamous cell carcinoma, and melanoma. The condition may cause symptoms like a persistent lump, red eye, or irritation. Diagnosis and treatment are crucial to prevent complications such as vision loss.
