[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]
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]

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 ...
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.
Of nonmelanoma skin cancers, about 80% are basal-cell cancers and 20% squamous-cell skin cancers. [14] Basal-cell and squamous-cell skin cancers rarely result in death. [6] In the United States, they were the cause of less than 0.1% of all cancer deaths. [1] Globally in 2012, melanoma occurred in 232,000 people and resulted in 55,000 deaths. [6]
A disadvantage with standard surgical excision is a reported higher recurrence rate of basal-cell cancers of the face, [41] especially around the eyelids, [42] nose, and facial structures. [43] There is no clear approach, nor clear research comparing the effectiveness of Mohs micrographic surgery versus surgical excision for BCC of the eye. [44]
Squamous-cell cancers of the lip and ears have high rates of local recurrence and distant metastasis. [27] In a recent study, it has also been shown that the deletion or severe down-regulation of a gene titled Tpl2 (tumor progression locus 2) may be involved in the progression of normal keratinocytes into becoming squamous-cell carcinoma.
