The long-term outcome of<unk> <unk>  carcinomas is dependent upon several factors: the sub-type of the carcinoma, available treatments, location and severity, and various patient health-related variables (accompanying diseases, age, etc.). Generally, the long-term outcome is positive, as less than 4% of<unk> <unk>  carcinoma cases are at risk of metastasis. When it does metastasize, the most common involved organs are the lungs, brain, bone and other<unk>  locations. One study found<unk> <unk>  carcinoma of the penis had a much greater rate of mortality than some other forms of<unk> <unk>  carcinoma, that is, about 23%, although this relatively high mortality rate may be associated with possibly latent diagnosis of the disease due to patients avoiding genital exams until the symptoms are debilitating, or refusal to submit to a possibly scarring operation upon the genitalia.<unk> <unk>  carcinoma occurring in the organ transplant population is also associated with a higher risk of mortality.
