Vitamin D in cancer breast patients during chemoradiotherapy

Vitamin D may help protect against breast cancer by slowing tumor progression, enhancing cancer cell death, and reducing metastasis. A study measured vitamin D levels in women with breast cancer before and after treatment, comparing them to a healthy control group, which surprisingly showed insufficient levels. Women with breast cancer had lower vitamin D levels initially, which decreased further after chemotherapy and radiotherapy. The findings suggest the need for vitamin D supplementation post-treatment. Emphasizing a diet rich in vitamin D and other nutrients, along with support from family and friends, can boost mood and immunity for these patients.
