Screening Prostate Cancer from your Pee

 Prostate cancer is the most common cancer amongst men, accounting for 26% of all new cancer cases. Like breast cancer, it has started to receive a lot of attention in an effort to inform and educate men about this condition. However, unlike breast cancer, trying to identify signs and symptoms early can be difficult. Women often undergo regular screening above the age of 50 with mammograms, and women can be taught to self examine.

Prostate cancer on the other hand, is not so easy to screen. Examination via a rectal exam is invasive, and maybe embarrassing for many patients. There is a blood test that collates to the prostate, known as Prostate Specific Antigen (PSA), and looking for a rise in the PSA can indicate malignancy. Unfortunately, its accuracy is as low as 30%, as many activities can cause a rise in PSA, even cycling. And it is not specific to Prostate Cancer, but rather the prostate itself, so inflammation, infection or prostatic hypertrophy can all cause an increase in PSA.

Is There a Link Between Vitamin E Capsules and Breast Enlargement?

  Vitamin E capsules are often marketed as a natural way to increase breast size. The theory is that vitamin E can help regulate hormones, which in turn can lead to breast growth. However, while there is some evidence to suggest that vitamin E can help to regulate hormones, there is no scientific evidence to suggest that it can lead to breast growth or enhancement.

However, while some studies have suggested that these herbal ingredients may have some estrogenic effects, there is little evidence to suggest that they...
