Vitamin D And Breast Cancer

Vitamin D And Breast Cancer
Recent research indicates that increased consumption of vitamin D through dietary intake and exposure to sunlight associated with reduced risk of breast cancer. provision of vitamin D can suppress the presence of cancer hormone receptor, namely estrogen receptor (ER) and progesterone receptor (PR).

Hormone receptors may be analogous to the ear in breast cells that will listen to signals from hormones. When the signal ordering grows, cancer cells will develop breast cells that contain receptors. Cancer will be called ER-positive (ER +) if the reason for the rise is a result of the receptor for the hormone estrogen. Meanwhile, if the reason for the rise is the presence of receptors for the hormone progresteron, called PR-positive (PR +).

Research linking vitamin D intake in the presence of hormone receptors was carried by Blackmore KM and colleagues from Mount Sinai Hospital in Ontario, Canada. Research done by comparing 758 breast cancer patients and 1135 control participants who do not have the disease. The researchers found that participants who intake of vitamin D experienced a high 26 percent decreased risk of breast cancer, ER and PR, and 21 percent decreased risk of ER or PR tumors. The study also indicates that vitamin D associated with reduced breast cancer risk regardless of whether the status of tumor ER or PR.

Vitamin D is found in many foods, such as fish oils, fortified foods, such as juice, cereal, and milk, and obtained by other means, such as exposure to sunlight.
