This video discusses the various ways in which cancer can be caused, including by viruses. It also discusses the importance of prevention, including through vaccination and keeping your environment clean.

• 00:00:00 Six times as many women develop cancer of the mammary gland than would be expected based on statistics for typical cancers. This investigation, led by Bruce Francis, MD, at the ABC Brisbane Cancer Center, may provide valuable information about one of the world's deadliest diseases. The documentary follows 16 women who developed cancer after working in a building that was later evacuated due to concerns about cancer contagion. Although no environmental cause was found, the mystery remains unresolved. The search for a cancer cause continues, with theories including a virus, radiation, chemical exposure, or a combination of factors. If found, this would be the first known cancer caused by a virus. Despite the high rates of cancer, finding a cure is still a dream for many doctors.
• 00:05:00 The documentary discusses how cancer is a disease that is increasing in incidence, and which has yet to be fully understood. They find a satisfactory explanation for this increase in risk, which is that we are facing either a mystery, something for which we do not have answers, or a simple coincidence, and never can be discounted as an explanation. It could be an explanation that holds water when there is a concentration of cancer cases, but there is no environmental factor that is clearly identifiable as the cause. However, their team has not explored the interior of tumor patients' yet. Breast cancer is not an inherited disease, and there are many different types of cancer localized in the mammary gland and less than 10% of these cancers are hereditary. We know the risk factors for cancer, but we do not know the cause. We cannot do anything without your participation. We need your help with tissue samples in this case, and your team will study the interior of tumors to look for a virus. This is a controversial idea, and it is not clear if viruses are the cause of breast cancer, and this idea continues to be very disputed. However, both sides have strong opinions, and we should not close ourselves to any possibility. We do not know what causes cancer of the chest,
• 00:10:00 In the 1970s, scientists working on cancer-fighting strategies focused their efforts on finding viruses that could cause the disease. They eventually found two viruses - the human papilloma virus (HPV) 16 and HPV 18 - that were responsible for most cervical cancers. Despite early skepticism, their research ultimately proved successful, and today we know that HPV 16 and HPV 18 are carcinogens. While progress has been made, we still have a lot to learn about HPV and its role in cancer. For example, in 2008, Cara Selby-Biggar received a Nobel Prize for her work on HPV and cervical cancer. She had spent more than 30 years trying to prove her theory.
• 00:15:00 The documentary discusses the reasons why cancer is a problem, and how viruses are believed to be the cause. It talks about the hope that came with the discovery that a virus could be the cause of cancer and how it would ultimately be solved if the virus could be stopped. One of the problems is that people don't always understand how cancer is caused, and that it can be caused by a number of infections during one's lifetime. Another problem is that it is difficult to ensure that girls receive the vaccine three times, and that they understand that they won't be protected if they don't receive it. This documentary is about introducing a new vaccine to prevent cervical cancer in children, and it is an ambitious project that is welcomed. The documentary talks about the challenges in getting the vaccine to where it is most needed, in developed countries. There are methods to prevent cancer cervical, but it is still an important project. It is necessary to implement programs that demonstrate that the vaccine works before more women die from this disease.
• 00:20:00 This video examines the possible link between cancer and the HPV virus, which is a common infection that can sometimes lead to cancer. Despite this link, however, the virus has not yet been shown to be the sole cause of cancer. Other factors, such as a person's age, sex, and diet, must also be in place for cancer to develop. Nevertheless, the discovery of the virus's potential role in cancer is still a very positive step forward in understanding the disease.
• 00:25:00 In the 1930s, scientists studying cancer in rats discovered that the disease was caused by a virus called Lymphocytic Neoplasm Virus (LNM). LNM is a very damaging virus that can enter and damage healthy cells. It is possible that LNM can also cause cancer in humans. However, some scientists are not convinced that rats can transmit cancer to humans. This video follows a team of scientists as they work to find a cure for cancer using the virus LNM. They are also investigating whether rats can be a virus vector for cancer in humans. If this is the case, it would mean that cancer could be preventable in some cases.
• 00:30:00 According to the narrator, the complexity of cancer is that researchers have not discovered anything that others have searched for and have not found, but their evidence is weak. This makes it easier to explain cancer as a result of contamination. I have read their articles and seen their evidence and am convinced that the data are incorrect and that there is no need to take them seriously. The debate has led experts to argue among themselves, with some believing that there is nothing that can't be true as a scientist. To me, what I see is work being done to make a discussion that should be suppressed. The story gets more complicated because it seems that there are different viruses involved in breast cancer, which would explain the different cases and behavior. This would be rational, with a great variety of viruses involved in different types of cancer. If this is true, then breast cancer would need to be re-planted practically every time someone gets it. So far, we have vaccinated over 20 million women worldwide with cervical cancer vaccine. However, some people in Vanuatu are afraid of the unknown, and the community does not seem to be convinced that they should vaccinate their children. There have been recent revisions to the vaccine program, and people are wondering why we are doing it
• 00:35:00 This video discusses the theory that cancer may be caused by a combination of genetic and environmental factors. It also explains how certain games of chance may increase the chances of developing cancer.
• 00:40:00 The video discusses the three international studies that suggest that a child's immune system "improves and strengthens" thanks to exposure to infections during their first year of life. The studies found that the less exposure a child has to other children, the less likely they are to develop leukemia. The first study, which was conducted in Brisbane, Australia, found that tumors in women aged 10 278 were caused by two genetic mutations. The study's team is now studying the results of 10 316 women's tumors. The second study, which was conducted in Perth, Australia, found that indicators of cancer were present in women for decades without anyone knowing what was causing them. The study's team found that, after finding out about bacteria's role in cancer, they were able to cure the disease by modifying the woman's lifestyle. The third study, which was conducted in Australia, found that cervical cancer is caused by infection, and that it takes many years for the infection to turn into cancer. The study's team was able to confirm this theory by studying the tumors of cancer patients who were infected many years, or even decades, after the infection occurred. The video concludes by saying that, although cervical cancer is caused by infection, most people don't develop
• 00:45:00 This documentary discusses the difficulties of developing a cure for cancer, as well as the importance of prevention. It discusses the work of Jane Fraser, who unsuccessfully attempted to develop a cure for cancer for almost 30 years. However, her team of local researchers will continue to work on the project on their own, and progress has been made in the past year. Although there is still no cure for cancer, this documentary shows that with persistence, anything is possible.
• 00:50:00 This video discusses the importance of discovering which viruses cause cancer, and the importance of vaccinating people against these viruses. The video also discusses the importance of keeping your environment clean to prevent infection.
