Uveal melanoma is a type of eye cancer in the uvea of the eye. [4] It is traditionally classed as originating in the iris, choroid, and ciliary body, but can also be divided into class I (low metastatic risk) and class II (high metastatic risk). [4] Symptoms include blurred vision, loss of vision, and photopsia, but there may be no symptoms. [5]
[3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process. [5] In medicine, a sign is an objective piece of data that can be measured or observed, as in a high body temperature (fever), a rash, or a bruise. [6]
Cutaneous squamous-cell carcinoma (cSCC), also known as squamous-cell carcinoma of the skin or squamous-cell skin cancer, is one of the three principal types of skin cancer, alongside basal-cell carcinoma and melanoma. [10] cSCC typically presents as a hard lump with a scaly surface, though it may also present as an ulcer. [1]
It causes fever, cough, and red eyes that may be sore and sensitive to light, spots in the mouth, and a splotchy, red rash that appears on the face and ears, then spreads down the chest and back ...
Of all cancers involving lymphocytes, 2% of cases are cutaneous T cell lymphomas. [13] CTCL is more common in men and in African-American people. [10] The incidence of CTCL in men is 1.6 times higher than in women. [10] There is some evidence of a relationship with human T-lymphotropic virus (HTLV) with the adult T-cell leukemia/lymphoma ...
Similarly, a cancer arising from malignant fat cells would be termed a liposarcoma. For some common cancers, the English organ name is used. For example, the most common type of breast cancer is called ductal carcinoma of the breast. Benign tumors (which are not cancers) are usually named using -oma as a suffix with the organ name as the root.
Retinoblastoma (Rb) is a rare form of cancer that rapidly develops from the immature cells of a retina, [2] the light-detecting tissue of the eye. [3] It is the most common primary malignant intraocular cancer in children, and 80% of retinoblastoma cases are first detected in those under 3 years old.
Recurrent cancers are much harder to cure, with a higher recurrence rate with any method of treatment. Although basal-cell carcinoma rarely metastasizes, it grows locally with invasion and destruction of local tissues. The cancer can impinge on vital structures like nerves and result in loss of sensation or loss of function or rarely death. The ...
