Do not eat fatty cancer cells?

Don't solve the "hunger therapy" of the tumor

Recently, "Nature · Metabolism"

Published a study

Cancer cell growth needs to be from the human body

Absorb a lot of fat

This reminds many people associate

Eat less and starve to hungry

Can you kill the malignant tumor?

Unfortunately died in 2011

Young female teacher Yu Juan, a young female teacher in Fudan University

There have been more than 70 "cancer diary"

Among them, there are records

"Hunger therapy" taught by "Folk Doctor"

Eat only a little taro and grapes every day

She is hungry and hungry, insisting on more than 40 days later

The condition deteriorates ...

So, the truth about the "hunger therapy" of tumor

What is it?

Hungry, hungry cancer cells

Can only starve to death

Fat is the raw material of synthetic cell membranes, which is closely related to the generation of new cells.

Studies have found that tumor cells use a large amount of oxygen to synthesize fat, obviously fat is very important for tumor cells. In a hypoxic environment, it is difficult for tumor cells to synthesize fats by themselves, and they will snatch a large number of fat from the human environment to maintain proliferation.

Tumor cells, like normal cells, need to "eat" things to survive and grow.

Scholars have been discovered that tumor cells have a particularly large need of various types of nutrients, and there are abnormal "vigorous" metabolism for nutrients such as glucose and amino acids. This may be one of the reasons why tumor cells can quickly proliferate.

But patients eat less and even do not eat, but they cannot threaten tumor cells. Because the way tumor cells obtain nutrients are plunder, even if the patient does not eat or drink, tumor cells can still consume the body and obtain nutrition.

At that time, it is only patients who are hungry. At the same time, malnutrition will also destroy the human body's own immunity, which is not conducive to tumor treatment.

"Hunger therapy" is only to make the tumor

"Hungry", cut off its nutritional supply

The concept of "hunger therapy" has been proposed for decades. It refers to blocking the nutritional channels of tumors through drugs or other methods, and it is not required to be hungry. There is no scientific basis for reducing the idea of ​​"starving tumors".

In 1971, Foxman, a professor of Harvard University, found that there was no blood vessel tumor, which could not even grow 1 mm in a month, and tumors with blood vessels could grow to 16,000 times the original volume in 3 days. Based on this, Foxman first proposed the theory of cutting off tumor blood vessels and starving to starve cancer cells.

In order to ensure the "smooth road network", the tumor will secrete the growth factor (VEGF), the private pull wire, the private highway, and the new blood vessels are generated in large quantities, and it is provided for itself. These blood vessels are like highways with tumor transportation resources. Tumors with blood vessels can quickly plunder the body's constant nutrition.

For the characteristics of tumors, drugs formed clinically using anti -blood vessels, such as Bervar, Abercip, Remomo Monopoly, etc., to inhibit new and growth of blood vessels. After clinical discovery of anti -vascular production, some types of tumors, especially the abundant blood supply, will shrink. Therefore, letting tumors starve is the correct way to enforce the "hunger therapy".

At present, there is also a very important treatment for liver tumors -TAE (TAE). "Embolism" to nourish the arteries of tumors, thereby "cut off" the "tumor life supply line" that transports nutrients.

While "arterial embolism", it can also be "infused with chemotherapy" drugs. After the catheter selectivity or ultra -selective insertion into the tumor blood supply arteries, the mixture of chemotherapy drugs and embolism is injected at an appropriate speed to prevent the target arteries occlusion and cause ischemia necrosis of the tumor tissue.

At the same time, chemotherapy drugs are settled in the tumor with the "embolic agent" and slowly released, which plays the role of "long -term" to eliminate tumors. This is "TACE".

Cancer patient recovery

A large amount of high -quality protein is indispensable

There are many legends about the diet of tumor patients. Among them, the most widely circulated is "not eating chicken".

Some opinions believe that chicken is a "hair product", which can easily lead to increased tumor increase and recurrence and worsen the condition. But in fact, there is no clinical evidence that eating chicken will harm the recovery of tumor patients.

Of course, some patients do need to limit the intake of protein, such as renal incompleteness, uremia or liver failure. Such patients need to control protein intake in the overall diet, not simply not eat chicken. Chicken contains a large amount of high -quality protein, which is conducive to recovery after surgery of tumor patients.

By adjusting diet, it is indeed conducive to tumor prevention and treatment. Some cancers are closely related to diet, such as pancreatic cancer and bowel cancer, which are generally considered to be related to the "three high" diet (high protein, high fat, high calories); Related; liver cancer is related to long -term intake of food, water pollution, and a large amount of alcohol contaminated by yellow glimading toxin.

Therefore, whether it is a normal population or a tumor patient who has been diagnosed, they should correct their dietary habits to achieve scientific balanced nutrition. Tumor patients who have already treated them will increase the risk of related tumor recurrence if they continue to eat properly.

Proper control of diet and adjustment of diet, such as low sugar and low fat, short -term eating during chemotherapy, is not harmful; patients with breast cancer and bowel cancer should try to control weight as much as possible without excessive obesity.

Looking for new targets for tumor treatment

Today, the research of some kinds of substances such as tumor preferences is endless, but this is not used as a clinical guide.These discoveries provide a breakthrough for anticancer therapy. If the cancer cells can be cut off the way to absorb fat, such as finding cancer cells to enter fat cell membrane receptors and develop targeted drug molecules for it so that they cannot obtain fat supply from the human body, soIt is expected to slow or prevent the proliferation of tumor cells.With the continuous deepening of the characteristics of tumor growth, it will help find new therapeutic targets."Starving tumor" is an aspect of comprehensive tumor treatment and an important anti -cancer idea.In addition, surgical resection, local minimally invasive therapy (Haifu knife, radio frequency ablation), combined system treatment (chemotherapy, targeted, traditional Chinese medicine), immunotherapy, etc. also play a pivotal role.

Do not exclude any formal treatment

Comprehensive science treatment

Only is it more conducive to the recovery of patients!
