In this month's cancer news review podcast, Dr. William Nelson, director of the Johns Hopkins Kimmel Cancer Center, discusses top cancer stories on sun related cancers, presmenopausal breast cancer, and prostate cancer patients with asthma and more.

First, Dr. Nelson speaks about research that examines the use of vitamin B3 (niacin) and skin cancers. Skin cancers other than melanomas have a high recurrence rate. Other studies have shown that the drug in vitamin B3 nicotinamide, when taken daily may be able to prevent these skin cancers from recurring. Dr. Nelson argues the findings may need to be reassessed in another clinical trial, but for now it's progress.

Next, Nelson discusses another recent study examining premenopausal women with breast cancer and assessing a family history of the disease.

Finally, this month's Cancer News Review examines a link between asthma and prostate cancer.  The study suggests that prostate patients with asthma may have a decreased risk of advanced disease.  This shows there is some complexity to the way the immune system responses.
