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, natural additive who has tried delay which stretch various types of cancer in mice and improved the effects of chemotherapy treatment, according to a study by Cancer Research UK and Cancer Research Worldwide, published this week in the journal Science nature,
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 used mannose – a type of sugar It can be found in fruits like blueberries, in mice with pancreatic, lung and skin cancer and found that tumor growth slowed down without causing side effects.
It is believed that mannose, easily accessible and sometimes used to treat urinary tract infections, prevents the use of glucose from tumors to grow, although experts conducting the study warn that no one should take mannose, believing it will be healed because they still have to do a lot more tests.
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 commonly used chemotherapeutic drugs, cisplatin and doxorubicin, the researchers found that Treatment of mannose increases the effects of chemotherapy, reducing the growth rate of the tumor and its size, the BBC Health Expert wrote.
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 Therine that his team found a dose of mannose that "can block enough glucose to slow tumor growth in mice, but not enough 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 investigation, but we hope that finding this perfect balance means that in the future, mannose may be given in cancer patients to improve chemotherapy without harming their general health"he added, recalling the warning that no one should supply only this natural supplement without consulting his physician.
