Throat Cancer Symptoms and Signs

Discolored tissues in the mouth. If strange patches appear inside the mouth, these could be an indication that there is a cancer present. Such patches could be white or red, or even black in color. Research by the Oral Cancer Foundation indicates that such cancers are generally caused by the Papillomavirus, which is known to cause oral cancers and cancers of the throat. HPV 16 is a particularly virulent Papillomavirus, and it can equally affect both men and women. If you notice these distinctive patches in your mouth, you may well be suffering from oropharyngeal cancer.
