Colorectal cancer is more common in developed countries (e.g. United States and Japan) compared to developing countries in Africa and Asia. Each year in the United States, there are around 150,000 cases of colorectal cancer diagnosed and about 50,000 people die from this cancer. Risk factors for colorectal cancer include lifestyle factors (e.g. habitual alcohol use; high-fat, low-fiber diet; obesity; sedentary lifestyle; smoking), family history of intestinal polyps or colorectal cancer, and medical conditions (e.g. diabetes, familial polyposis syndromes, hereditary non-polyposis colon cancer syndrome, inflammatory bowel disease, intestinal polyps).

There are three types of MM; pleural mesothelioma, peritoneal mesothelioma, and pericardial mesothelioma, affecting the lining of the lungs, abdominal cavity, and lining of the heart, respectively (1). Pleural mesothelioma is most common, consisting of about 70% of all MM cases and has a poor prognosis; patients live a median time of 18 months after diagnosis. (Note: for the purposes of this article, MM will be used to represent pleural mesothelioma exclusively.) Despite its discovery in the mid-1800's, MM was not linked to asbestos until the late 1900's, when case reports of fast-growing lung cancers, different from prev...

However, many proprietary mouthwashes including my favorite brand contain Alcohol (ethanol) which also gives them the characteristic burn we have to endure, albeit for a few seconds each day, but safe in the knowledge that the product is hard at work killing all the germs that give us bad breath and may cause plaque and gingivitis. But the question I continually ask myself is whether regular or long term use of these products i...

There are well over 100 subtypes of HPV. The subtypes that infect cutaneous epithelia are termed beta-HPVs and those that infect the mucosal epithelia are termed alpha-HPVs. Some alpha-HPVs have received attention as strong risk factors for the development of cervical cancer. Less public awareness has been generated over the role of HPVs in the development of other cancers such as vulvar, vaginal, anal, head and neck, and penile cancers. Only recent research has focused on an association between HPV infection and skin cancer development. Infection with beta-HPVs and development of skin cancer was first identified in patients with a rare inherited disorder called epi...

When I found out my only non-smoking cousin had nasopharyngeal carcinoma (NPC), I was puzzled. With all the hype about cigarette smoking associated with various kinds of cancers in the media, I did not understand why none of my smoking cousins had NPC but the one who didn't smoke did. At first, I thought it must be due to the second hand smoke. Now, I understand that the picture is very complex. Before I go into what I have learned over the past several months, I need to make a disclaimer. I am not an expert in NPC. I am an average college student. This is what I have learned. Back to my story, the first thing I did when I heard the news was to do a search on what NPC is and what are some of the current risk factors associated with it. According to the A...

Although its pathogenesis has been studied for only about the past 20 years, there are reports from as far back as the late 19th century of small, helical bacteria in the stomachs of some patients. Largely these anecdotal reports were relegated to the "hmm, interesting" file and not followed up for many years. It wasn't necessarily that others didn't follow (or care about) the research; the lack of studies on them, despite occasional reports in the literature, is probably due more to the fact that we hadn't figured out yet how to culture them outside of the body. Prior to the era of molecular biology, this made studies of bacteria such as Helicobacter difficult, if not impossible. However, studies bega...

Does chronic IL-6 levels lead to epigenetic changes in DNA methylation that contribute to this pathway? By Matthew Fitzgerald How can infection be a carcinogen? How do infectious diseases lead to cancer, if at all, is still a highly debated area of research. Do infectious diseases change the genetic information by insertions, mutation, or do bacterial toxins act as carcinogens? Does inflammation lead to free radical damage and cancer? While all of these and more are possible causes, another potential mechanism is that infection could change the epigenetics of cells at the site of infection. What is epigenetics? It is how our genetic information is controlled to tell cells what genes should be expressed and what genes...

By Ousmane Diallo I was dumbfounded when I read this news article relating HPV to the increase of lip and oral cancers because of oral sex. It reminded me my younger years, as a med student, debating with my professor of psychology the fundamentals of Freudian psychoanalysis, the Id, the Ego and the Super-ego. It was a rather philosophical debate more than anything else, a combination of religious and cultural reciprocal statements of beliefs. At that time, we were exposed to the new French "sexual education" magazine called Union, borderline Playboy and X-rated. Even though we were colonized for one hundred years, sang the Marseillaise at elementary school, believed like the Koran that we were the descendants...

Cancer researchers have for decades known that viruses can cause cancer. It is now estimated that 15% of the world's cancers are caused by infectious diseases including viruses. Some of these include: Human Papilloma Virus (HPV) and cervical cancer; Epstein-Barr Virus (EBV) and nasopharyngeal cancer & lymphoma; Hepatitis B and liver cancer. In fact cancer researchers use this knowledge of viruses causing cancer by utilizing EBV and SV40 and other viruses to "immortalize" cells in their labs to have better cancer models. These "immortalized" cells keep dividing and act like cancer cells so that researchers can continually propagate their experiments. It is believed t...

As I mentioned then: While we know a good deal about factors that can contribute to breast cancer risk--including genetics (such as mutations in the BRCA1 and BRCA2 genes) and lifestyle choices (late or no childbearing, high fat diet, lack of exercise), many environmental risks for breast cancer remain controversial. Even the effect of cigarette smoking on breast cancer development remains uncertain, as does the environmental light idea.

Duesberg's cancer ideas--and his claim of novelty for researching how chromosomal abnormalities, rather than more simpler gene mutations, cause cancer--are something I wanted to write about months ago, after I came across an interesting reference in this post over at Panda's Thumb, where it was noted that "...in certain kinds of cancer, chromosomal instability prevents tumourogenesis, the exact opposite of what Wells [and Duesberg--TS] predicted."
