A majority of patients with small kidney tumors have their entire kidney removed, despite the availability of organ-sparing surgery. Studies show that partial nephrectomy is just as effective in controlling cancer while preserving long-term kidney function. However, its infrequent use may be due to surgeon expertise and hospital policies.
Researchers discovered that vitamin D significantly limits the ability of prostate cancer cells to invade healthy cells by reducing two key enzymes. Vitamin D also increases counterpart enzymes that inhibit these proteases, leading to reduced cancer progression.

A new study published in The American Journal of Medicine reveals that a high-carb, vegan diet leads to significant weight loss and improved insulin sensitivity. With unlimited servings of fruits, vegetables, and whole grains, this low-fat diet is also associated with lower rates of prostate cancer and various life-threatening diseases.
Prostate cancer cells manipulate Wnt signaling proteins to establish themselves in bone tissue, producing dense bony lesions characteristic of prostate cancer. The study found that altered levels of Wnt activity promote osteoblastic lesions, while high levels of DKK-1 inhibit Wnt activity, leading to highly osteolytic tumor lesions.
A Stanford study found that combining vitamin D and nonsteroidal anti-inflammatory drugs (NSAIDs) suppresses prostate cancer growth more effectively than using either drug alone. The researchers discovered a 25-70% reduction in cell growth when calcitriol was used with NSAIDs, with potential implications for new treatment options.
