The American age-adjusted incidence rate for prostate cancer peaked in 1992 at 237.4 per 100,000 men with the advent of widespread PSA screening and has been falling fast ever since. The age-adjusted mortality rate for prostate cancer peaked in 1993 — just a year after the incidence rate did — at 39.3 per 100,000 men. Explanations for the decline in the mortality rate range from improvements in treatment to American men having healthier diets. Advocates of screening say early detection has also had a hand in bending the mortality-rate curve. Read the article.

Howard Wolinsky a journalist based in the Chicago area, was diagnosed with early prostate cancer in 2010. In part one of a series he described his diagnosis and his decision to chose active surveillance. In the second part, he shared his experience during 5 years of active surveillance and in this part he tells his continuing quest to make the best — and most informed — decision about his care. Howard Wolinsky decides it may all be in the genes. Read the article.

Most people would agree that it would be better to prevent cancer, if we could, than to treat it once it developed. Yet economic incentives encourage researchers to focus on treatment rather than prevention. Read the article.

New research suggests that age, race and family history are the biggest risk factors for a man to develop prostate cancer, although high blood pressure, high cholesterol, vitamin D deficiency, inflammation of prostate, and vasectomy also add to the risk. In contrast, obesity, alcohol abuse, and smoking show a negative association with the disease. Details are reported in the International Journal of Medical Engineering and Informatics.

Men who have an orgasm a day are lowering their risk of developing prostate cancer. A study has revealed that those men who ejaculate more often during their lifetime have a 22% lower risk of getting the disease. The study doesn’t give any reasons why the practice of ejaculation may help to stave off prostate cancer, but there are theories which have been made public previously. It has been thought that ejaculation can rid the prostate of cancer-causing chemicals, while there are also theories that if sperm is ‘cleaned out’ in this manner it can stop a build-up of old

New research has revealed that five different types of prostate cancer exist. World renowned robotic prostate cancer surgeon, Dr. David Samadi says this discovery may change the outlook of prostate cancer screening. “Discovering five different types of the disease could change how they’re distinguished from one another and may even mean different treatments for each, targeted to the individual patient,” said Dr. Samadi, Chairman of Urology and Chief of Robotic Surgery at Lenox Hill Hospital in New York City.

Scientists at the UW Carbone Cancer Center are in human trial phase for a vaccine to treat aggressive forms of prostate cancer. Scientists say this vaccine, combined with another drug, will help the body target prostate cancer cells. “We believe this vaccine has the potential to train a patient who has prostate cancer, to train their immune system to recognize the tumors that are growing as foreign and to begin to clear them and remove them from the body,” said Dr. Richard Lesniewski, the president and CEO of Madison Vaccines.

A vaccine has been developed to help prevent the recurrence of prostate cancer, and potentially other cancers. It’s designed to teach the immune system to recognise compounds found in prostate cancer cells and is being given to men who have already been treated for the cancer. The vaccine is made from pieces of a protein called TARP that’s found in about 95 per cent of prostate cancers. Animal studies have shown that the protein can effectively stimulate the immune system to attack the cancer. Read the article.
