Oncoviruses (Cancer Causing Viruses
Oncoviruses are viruses that can cause cancer.
Technically any virus with a DNA or RNA genome causing cancer is synonymous with 'tumor virus' or 'cancer virus'. Most viruses do not cause cancer but the WHO (World Health Organization) estimates that virus infections cause 18% of human cancers and a group of seven (7) viruses cause nearly 12% of cancers. The list below shows 7 types that are most commonly known to cause cancer. Others may reveal themselves as cancer-causing in the future.
At present, there are few options for treating virus infections and most efforts are directed toward immunization with specific vaccines. An example is the papillomavirus vaccine which helps to prevent cervical cancer.
Likewise, many of the legacy treatments for cancer (surgery, chemo and radiation) do not address the viral issue and are targeted towards reducing or eliminating the abnormal cells.
PDT however, has proven to both reduce cervical cancer and help to reduce or eliminate the Human Papilloma Virus simultaneously.
With the breakthrough use of ultrasound to activate sensitizers attached to both the abnormal cells and the cancer-causing viruses, it may well lead to more effective and durable success in the treatment of the virus-related cancers. This will be revealed as a result of the increasing use of SPDT in the treatment of both cancer and viral infections.
It is observed that chronic viral hepatitis infections lead to liver cancer in many patients and it may be that the use of SPDT for chronic hepatitis virus infections reduces viral load (and perhaps leads to auto-vaccination) and coincidentally results in fewer progressions to liver cancer. Similar enhanced success with the above-listed virus-related cancers may occur with the advent of the 'full body' sensitizer activation on both viruses and cancer cells.
