The body can not live without glucose. Sugar in the blood is part of what feeds the body tissues to grow. The problem is that cancer cells also use it to spread. Scientists now believe they have found a way to break this supply.
And this is through mannose sugar, a natural supplement that has been shown to slow the spread of various cancers in mice and improve the effects of chemotherapy treatment, according to a study conducted by Cancer Research UK and Cancer Reasearch Worldwide published this week in the scientific Nature magazine.
Although the results are mice, scientists in charge of the study hope that they will be applicable to patients, but they have to do more tests, BBC journalist Alex Terrien said.
For the experiment, the research team has applied mannose – a type of sugar that can be found in fruits such as blueberries, mice with pancreatic cancer, lung and skin, and it is found that tumor growth slows down without causing side effects.
Mannosa, which is readily available and sometimes used to treat urinary tract infections, is believed to prevent the growth of glucose tumors, although the investigating experts warn that no one should take mannose, believing it will heal because many more tests have to be done.
More affective treatment
Mannose has proven to be not only good for preventing cancer, but has improved the results of some treatments.
In mice treated with two of the most widely used chemotherapeutic drugs, cisplatin and doxorubicin, the researchers found that mannose treatment increases the effects of chemotherapy, slowing the rate of tumor growth and its size, he writes. the BBC health expert.
In the case of other cancers, such as leukemia, osteosarcoma (bone cancer), ovarian and intestinal cancer, some cells respond well to mannose and others do not. Their response seems to depend on the levels that these cells have an enzyme that breaks down this sugar.
Leading author, Professor Kevin Ryan of the Beatons Institute of Cancer Research, told BBC's Alex Terrien that his team found a dose of mannose that "can block enough glucose to slow tumor growth in mice, but not so much, to prevent the growth of normal tissues. "
The bodies require glucose for energy, but cancerous tumors also use it to stimulate growth.
"This is an initial study, but we hope that finding this perfect balance means that in the future mannose can be given to cancer patients to improve chemotherapy without harming their overall health," he added, reminding You must supply this natural supplement yourself without consulting your doctor.
