Serum calcium and Breast Cancer risk: results from a prospective cohort study of 7,847 women. Cancer Causes Control. 2007 Aug;18(6):595-602. Epub 2007 Apr 5. Showed increased risk of breast cancer in women with untreated hyperparathyroidism. (This has been shown in 6 studies that we are aware of).
A dramatic increase in the rate of aggressive Prostate Cancer was shown several years ago, but most recently in 2008 it was shown in a very large study in the US in cooperation with the National Institutes of Health (NIH). High calcium and PTH are associated with a 2.7-fold increase in aggressive prostate cancer. Read the abstract of this journal article here: Cancer Epidemiology Biomarkers & Prevention 17, 2302-2305, September 1, 2008. where they summarize by saying "These results support the hypothesis that high serum calcium or a factor strongly associated with it (e.g., high serum parathyroid hormone) increases the risk for fatal prostate cancer". And, you can read about it here on Yahoo also: High blood calcium tied to lethal prostate cancer.
The association between primary hyperparathyroidism and malignancy: nationwide cohort analysis on cancer incidence after parathyroidectomy. Endocr Relat Cancer. 2007 Mar;14(1):135-40. Showed increased incidence of breast, colon, and kidney cancer in patients with hyperparathyroidism.
