Alternative medicine kills cancer patients, “complementary” edition
By definition, alternative medicine has not been shown to be effective or has been shown to be ineffective. Thus, alternative medicine is ineffective against cancer and can best be represented as either no treatment at all or potentially harmful treatment. It is thus not surprising that cancer patients who choose alternative medicine have a higher risk of dying from their cancer. A...
Vitamin D and the relationship to colon cancer
Colorectal cancer is common. A new study examines the relationship with vitamin D levels.
When science- and evidence-based guidelines conflict with patient wishes: What’s a doc to do?
We use the term "science-based medicine" (SBM) because medicine isn't a science. The best medicine, however, is based in science. Patient values are also important, but what is a science-based doctor to do when SBM conflicts with what a patient or family wants?

Yes, diet and exercise can be useful to prevent some cancers. Unfortunately, they don't prevent all cancers, and the effect size is more modest than often represented. That's not to say that eating right and exercise aren't good. They are, for so many other reasons than cancer. Just don't view them as a panacea for preventing cancer.
Colonoscopy and Other Colorectal Cancer Screening Options: An Update
When I wrote about colonoscopy in 2010, colonoscopy was thought to be the best screening test for colorectal cancer because it could visualize the entire colon and could remove adenomas that were precursors of cancer. But only fecal occult blood testing (FOBT) and sigmoidoscopy had been proven to decrease colorectal cancer incidence and mortality (by 16% and 28%, respectively). Observational evidence suggested...
CAM as a Dumping Ground
I know a woman who is a survivor of colorectal cancer. At one point, doctors had given up hope and put her in hospice, but she failed to die as predicted and was eventually discharged. She continues to suffer intractable symptoms of pain with alternating diarrhea and constipation. I don’t have access to her medical records, but she tells me her doctors...
Questioning Colonoscopy
Everybody knows that colonoscopy is the best test to screen for colorectal cancer and that colonoscopies save lives. Everybody may be wrong. Colonoscopy is increasingly viewed as the gold standard for colorectal cancer screening, but its reputation is not based on solid evidence. In reality, it is not yet known for certain whether colonoscopy can help reduce the number of deaths from...
