Vitamin D Against Breast Cancer

Scientific studies confirm that a higher level of vitamin D in the blood reduces the risk of breast cancer. Especially in the northern latitudes, many people suffer from vitamin D deficiency – the consequences can be serious. It is therefore essential to prevent a vitamin D deficiency!

Breast cancer is more common

Breast cancer is being diagnosed more and more often in young women. The chances of recovery predicted by the doctors are apparently 90 percent, but only if the breast cancer is detected in good time. However, treatment methods such as chemotherapy or breast amputation scare most women with this disease.

Prevent breast cancer with vitamin D

Of course, the constantly increasing incidence rates make research into new diagnostic and therapeutic options for breast cancer particularly interesting for scientists and pharmaceutical companies. In our opinion, however, the prevention of breast cancer is much more important than diagnosis and treatment.

It has long been known that a high vitamin D level can reduce the risk of breast cancer. This has been proven in various studies.

Studies show that vitamin D reduces the risk of breast cancer

In a study with 67,721 French women in 2011, scientists were able to show that a certain vitamin D blood level can reduce the risk of breast cancer.

In the USA, other scientists checked this connection between a high vitamin D level and the reduced risk of breast cancer using the so-called Hill criteria.

(The Hill criteria are a medically recognized questionnaire to assess a connection between a cause and the occurrence of a clinical picture.) This study also confirmed that vitamin D reduces the risk of breast cancer.

Vitamin D deficiency is widespread

If you want to prevent breast cancer and other diseases associated with vitamin D deficiency, you should definitely ensure a balanced intake of vitamin D. But nowadays many people suffer – often unknowingly – from a vitamin D deficiency.

Especially in the northern latitudes, the sunlight is not sufficient for healthy vitamin D production in the skin, especially in the winter months. Therefore, especially in these areas, many people suffer from a vitamin D deficiency. This was also confirmed by Ad Brand from the Sunlight Research Forum in a press release:

The modern lifestyle contributes to the fact that many women in the western world do not spend enough time in the sun. Although short-term UV exposure is sufficient for vitamin D production, many women in the western world suffer from a severe vitamin D deficiency. A high vitamin D level reduces the risk of breast cancer and also protects against many other diseases. In the northern hemisphere, the sunshine from September to March is often not sufficient to produce enough of the vital vitamin D.

Ensure vitamin D supply

If you live in a place where the sun shines only a little, you can also ensure your vitamin D supply with the help of alternative vitamin D sources. The tanning bed is one possibility. However, solariums should only be used in a targeted and moderate manner.

Although new devices now deliver a balanced UVA/UVB mix (only UVB radiation leads to vitamin D formation in the skin), you should always seek advice from a specialist as to which setting and duration are suitable for your skin type.

In addition to the tanning bed, a full-spectrum light bulb can also be used at home or in the office to produce more vitamin D in the body. In this case, however, you should ask the manufacturer for proof that the lamp in question actually activates vitamin D production.

In addition to the body’s own production of vitamin D using UVB or sunlight, vitamin D can also be ingested through food. However, the amount of vitamin D in foods that are typically considered rich in vitamin D (salmon, mackerel, egg yolk) is too low (or one does not eat sufficient amounts of it every day) to permanently meet the vitamin D requirement cover so that food is not considered a reliable source of vitamin D.

Vitamin D has long been available in the form of vitamin D3 capsules, which can be taken as a dietary supplement, especially in the winter months, to safely avoid a vitamin D deficiency.

But you can also continue taking vitamin D supplements in summer if you don’t spend much time outdoors or if you have to use sun protection because of very sensitive skin.
