Vitamin D Breast Cancer Prevention
Vitamin D is a group of fat-soluble prohormone (substances that have only a little hormonal activity but can be transformed into a body hormone). Vitamin D helps the body use calcium and phosphorus to make strong bones and teeth. The skin is exposed to sunlight can produce vitamin d. Vitamin D can also be obtained from certain foods. Vitamin D deficiency can cause brittleness in bones called rickets in children and osteomalacia in adults.
Vitamin D is needed can be obtained from sun exposure. Source of food can include fatty fish, fish liver oil, and eggs. However, most vitamin D found in milk, juices and cereals. Vitamin D can also be obtained from supplements.
Does vitamin D linked to breast cancer?
Studies have found that vitamin D can reduce the risk of heart disease, fractures, and even depression. Now, recent research proves that breast cancer patients with vitamin levels are more likely to survive in the blood than patients with low levels of the vitamin.
The research found that women with breast cancer who had low levels of vitamin D have a risk of the return of cancer 2 times higher, and nearly twice the risk of death compared to women who have a high vitamin D levels.
Animal data to find potential anticarcinogenic effects on calcium and vitamin D in breast cancer development. The intake of calcium and vitamin D are higher may be associated with decreased risk of breast cancer before menopause. Protection on women who are menopausal yet more devoted to aggressive breast tumors.
On the experts found that women with low vitamin D levels are more easily affected by breast cancer, in which breast cancer patients with high levels of vitamin D have a lower mortality rate by as much as 50%. The metabolism of vitamin D increases the communication between cells by activating proteins that stop cell division that aggressively. During the existence of the vitamin D receptor, tumor growth can be prevented from spreading the blood supply.
Therefore, vitamin D is believed to have an important role in protecting the breast cancer, in which vitamin D make breast cells on more "clever" because there are vitamin D receptors in breast tissue, and vitamin D receptor can bind to it. This can cause such cells stop growing or die oncogenes. What's more, the cancer cells can not be spread in other parts of the body.
Other research shows vitamin D levels of embeddedness and rekurensi breast cancer, tumor size, and deaths from breast cancer. These things contribute to the results at which have enough vitamin D can avoid worsening the condition of cancer.
However, the relationship between breast cancer with vitamin D is very complicated, it is not fully understood, and it is still in the process of research. Another study found a dose-response relationship, where any increased levels of vitamin D in the body, there is a decreased risk of breast cancer. Most research is observational study, so the investigators could not verify whether vitamin D can prevent breast cancer or not.
Although most people rarely have high vitamin D intake, it is important to remember that excess intake of any nutrients, including vitamin D, can cause toxic effects. Too much vitamin D can be dangerous because it increases the levels of calcium, which can cause kalsinosis (salt buildup of calcium in soft tissues such as the kidneys, heart or lungs) and hypercalcemia (high levels of calcium in the blood). Maximum levels of intake of vitamin D is safe for adults and children over 8 years old was 100 μg per day (4000 IU per day).
Poisoning due to too much vitamin D more likely to occur due to excess consumption of vitamin D supplements, rather than from foods that contain vitamin d. exposure to excess sunlight will not cause poisoning vitamin d. but do not increase the production of vitamin D with increased sun exposure because it can cause the risk of skin cancer. Always consult your doctor before taking vitamin D supplements.
