According to the latest analysis of clinical trials, taking vitamin D can prolong the life of cancer patients.
Researchers at Michigan State University (MGU) in East Lansing analyzed data from a randomized controlled trial that people took dietary supplements with vitamin D compared to those who received placebo for at least 3 years.
They included only studies that have examined the use of vitamin D supplements for disease prevention for at least four years and also registered cancer cases and cancer-related deaths.
In total, the analysis was carried out in 10 studies with a total of 79,055 participants. Their average age is 68 years and 78% of them are women.
The team found a significant relationship between intake of vitamin D supplements and lower risk of death from cancer during follow-up.
Analysis showed that people taking vitamin D supplements had a 13% lower risk of dying from cancer than those who used placebo during the same period.
However, there is no significant correlation between vitamin D use and cancer prevention.
The results will be included at the Annual Meeting of the American Society of Clinical Oncology (ASCO), Chicago, IL, June 3, 2019
The latest additions to the ASCO Clinical Oncology Journal also include a summary of the study.
“The difference in mortality between the vitamin D group and placebo was statistically significant enough to show how important it was among the cancer population,” said Tarek’s rise in internal medicine to UMG and one of the study’s leading authors.
Cancer and Vitamin D
According to the World Health Organization (WHO), cancer is the second most common cause of death in the world. In 2018, around 18.1 million people found that they had cancer, and 9.6 million died of the disease.
Cancer occurs when cells multiply abnormally and form tumors that can spread. There are many forms of cancer, depending on the type of cage and the body part where it starts.
Under normal circumstances, cells will die if they are damaged or aging, and new ones will replace them. Cancer occurs when this process stops functioning properly, which means that old cells are damaged or do not die or too many new cells are formed. This dysfunction can cause excess cells to get out of control.
When cancer develops, it begins to spread to the closest tissue. At the same time, the cells that come out of the tumor cannot spread through the lymphatic system and blood flow to other parts of the body and start new secondary tumors.
The chances of surviving cancer are much higher if the diagnosis is made earlier and treatment can begin before the disease begins to spread. After the cancer has spread or spread, it is more difficult to heal.
Most people get vitamin D when exposed to sunlight and food. Some also take vitamin D. The body must convert vitamin D into an active form before using it. This process takes place in two phases: first in the liver and then in the kidney.
After being in active form, vitamin D helps the intestines absorb calcium during digestion and keeps blood levels stable for use in bone formation. This also helps maintain bone health. Health problems such as childhood rickets and osteoporosis in the elderly may be caused by vitamin D deficiency.
Vitamin D is not only important for bone health, but also helps control cell growth, immune function and inflammation. It performs these functions by regulating genes for cell differentiation, division and death.
