Kalsium dan Kanker Prostat

Para pria berhati-hatilah dengan kalsium yang berlebihan. Karena menurut analisis terbaru yang dilakukan oleh Wake Forest University School of Medicine dan University of Wisconsin, kadar kalsium yang berlebihan di dalam aliran darah laki-laki bisa meningkatkan resiko kanker prostat yang serius. “Hal ini terjadi karena distribusi serum kalsium sudah diatas kadar normal,” ujar Gary G. Schwartz, Ph.D, Assoc. Professor pada bidang Epidemiologi dan Biologi Kanker pada Wake Forest University.

Hasil riset yang dirilis dalam jurnal American Association for Cancer Research, menyebutkan 2.184 laki-laki yang menjadi sukarelawan, diteliti dan diukur kadar kalsium dalam darahnya kurang lebih sembilan tahun sebelum terdiagnosis kanker prostat.

Dari keseluruhan sukarelawan, peneliti memfokuskan pada 85 kasus kanker prostat dan 25 kasus kematian yang disebabkan kanker ini. Mereka dibagi berdasarkan tingkatan serum kalsiumnya. “Ternyata, kami mendapatkan hasil yang signifikan terhadap besarnya peluang kanker prostat,” imbuh Halcyon G. Skinner, peneliti lainnya. Menurutnya, hasil laboratorium menunjukkan bahwa baik kalsium maupun hormon parathyroid bisa memicu pertumbuhan sel kanker prostat. Kadar kalsium yang aman di dalam darah adalah di bawah 7 mg/desiliter dan jika diatas 14 mg bisa menyebabkan koma.
