Eye cancer

Origin and location

Eye cancers can be primary (starts within the eye) and metastatic cancer (spread to the eye from another organ). The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer. Other less common sites of origin include the prostate, kidney, thyroid, skin, colon lymphoma and leukemia. Metastasis (Greek: change of the state) is the spread of cancer from its primary site to other places in the body. ... Breast cancer is cancer of breast tissue. ... Lung cancer is the malignant transformation and expansion of lung tissue, and is the most lethal of all cancers worldwide, responsible for 1. ... The prostate is a compound tubuloalveolar exocrine gland of the male mammalian reproductive system. ... The kidneys are organs that filter wastes (such as urea) from the blood and excrete them, along with water, as urine. ... In zootomy and dermatology, skin is the largest organ of the integumentary system made up of multiple layers of epithelial tissues that guard underlying muscles and organs. ... Leukemia or leukaemia (see spelling differences) is a cancer of the blood or bone marrow and is characterized by an abnormal proliferation (production by multiplication) of blood cells, usually white blood cells (leukocytes). ...


Types

Tumors in the eye and orbit can be benign like dermoid cysts, or malignant like rhabdomyosarcoma and retinoblastoma. The most common eyelid tumor is called basal cell carcinoma. This tumor can grow around the eye but rarely spreads to other parts of the body. Other types of common eyelid cancers include squamous carcinoma, sebaceous carcinoma and malignant melanoma. Look up Benign in Wiktionary, the free dictionary. ... A dermoid cyst is a teratoma that contains developmentally mature skin, with hair follicles and sweat glands, sometimes luxuriant clumps of long hair, and often pockets of sebum, blood, or fat. ... In medicine, malignant is a clinical term that means to be severe and become progressively worse, as in malignant hypertension. ... A rhabdomyosarcoma is a type of cancer, specifically a sarcoma (cancer of connective tissues), in which the cancer cells are thought to arise from skeletal muscle progenitors. ... // Retinoblastoma is a cancer of the retina. ... Basal cell carcinoma (BCC) is the most common skin cancer. ... Biopsy of a highly differentiated squamous cell carcinoma of the mouth. ... Melanoma is a malignant tumor of melanocytes. ...


The most common malignant primary intraocular tumor in adults is melanoma. Though most attention is given to posterior choroidal melanoma, these tumors can also occur in the iris and ciliary body. Then they are called iris or ciliary body melanoma. Melanoma is a malignant tumor of melanocytes which are found predominantly in skin but also in the bowel and the eye (see uveal melanoma). ... The human iris The iris is the green/grey/brown area. ... Schematic diagram of the human eye The ciliary body is the part of the eye containing the ciliary muscle and ciliary processes. ...

The most common malignant intraocular tumor in children is called retinoblastoma. Affecting approximately 325 children per year in North America, early detection has allowed for cures exceeding 95%.[citation needed] // Retinoblastoma is a cancer of the retina. ...


The most common orbital malignancy is orbital lymphoma. This tumor can be diagnosed by biopsy with histopathologic and immunohistochemical analysis. Most patients with orbital lymphoma can be offered chemotherapy or radiation therapy. Chemotherapy is the use of chemical substances to treat disease. ... Clinac 2100 C100 accelerator Radiation therapy (or radiotherapy) is the medical use of ionizing radiation as part of cancer treatment to control malignant cells (not to be confused with radiology, the use of radiation in medical imaging and diagnosis). ...


Orbital dermoid cysts are benign choristomas which are typically found at the junction of sutures, most commonly at the fronto-zygomatic suture. Large deep orbital dermoid cysts can have cause pressure effects on the muscles and optic nerve, leading to diplopia and loss of vision. The term orbital has several meanings: In physics and chemistry it is used to describe an atomic electron configuration, see also molecular orbital and atomic orbital. ...

Ocular oncology

Ocular oncology takes into consideration that the primary requirement for patients is preservation of life by removal of the tumor, along with best efforts directed at preservation of useful vision, followed by cosmetic appearance. The treatment of ocular tumors is generally a multi-specialty effort, requiring coordination between the ophthalmologist, medical oncologist, radiation specialist, head & neck surgeon / ENT surgeon, pediatrician/internal medicine/hospitalist and a multidisciplinary team of support staff and nurses. Oncology is the branch of medicine that studies tumors (cancer) and seeks to understand their development, diagnosis, treatment, and prevention. ...
