Eight Cancer Rumors
The latest data show that the incidence of cancer has been on the rise for a decade.
The brutality of cancer has drawn special attention to a variety of prevention methods.
Some of them are half right and half wrong, and some are purely rumors. They are spreading wildly on the Internet, causing major panic, and some others do the same, seriously threatening their lives.
Therefore, the editor summarized several of the most widely spread rumors, and invited authoritative experts in oncology to restore the truth.
Myth 1: People with good genes are less likely to get cancer.
Some people smoke and smoke their whole lives and eat and drink without cancer.
Some people have a genetic history at home, and they also develop cancer without smoking or drinking.
Truth: Genetic factors are indeed one of the most important cancer risk factors, but some cancers have different genetic traits, and their genetics are significantly different.
There is a proto-oncogene in our body, which is a normal gene of the cell. When the proto-oncogene undergoes structural changes or overexpression, it may cause cell canceration.
Smoking, air pollution, ionizing radiation, excess and other factors may cause certain gene mutations, cells grow disorderly, continue to accumulate like snowballs, and form slender tumors.
Myth 2: Cancer is contagious.
Cervical cancer, nose and throat cancer, and gastric cancer are all related to viral and bacterial infections. Can cancer also be transmitted?
The truth: About 16% of cancer patients worldwide are associated with chronic infections, and the reduction may reach 23%.
The high incidence of gastric cancer is not unrelated to Helicobacter pylori infection. The transmission of this bacterium is mainly co-meal and mouth-to-mouth feeding. Cervical cancer is related to human papilloma virus (HPV) infection.Sexual customs are high in many open cities; the incidence of nasopharyngeal cancer is also related to viral infections.
However, viral carcinogenesis is an indirect, long-term process. It is impossible to transmit cancer through physical contact with cancer patients and eating together.
But maintaining good hygiene habits can help reduce the risk of infection and help prevent some cancers.
Rumor Three: Deep races are not prone to skin cancer.
Some people think that people with white skin are more susceptible to UV damage, while people with deep skin are less likely to develop skin cancer.
Truth: Light-skinned people are more sensitive to light and more likely to sunburn, and the elderly increase the risk of skin cancer and melanoma.
But people of deep ethnicity are not at ease.
Due to the deep skin tone, the skin of the nails, palms, soles of the feet, genitals, etc. may be missed, but it is easy to miss diagnosis.
So, regardless of race, you should pay attention to sun protection in summer or in high altitude environment, 11 noon?
Avoid exposure at 16 o’clock.
Myth 4: “Acid foods” cause cancer.
”Acidic foods” cause the blood to become sour, which in turn increases the risk of cancer.
Eat more “alkaline foods”, a small amount of leafy greens and fruits can prevent cancer.
The truth: The microenvironment surrounding polymers can be acidic, because the metabolic pathways of tumor tissue are different from normal tissues.
Scientists are trying to figure out how this change will help cancer treatment.
But there is no evidence that diet can change the pH of the body.
The blood is slightly alkaline, and the kidneys can maintain the blood’s pH value (hydrogen ion concentration value) only within a small normal range, but eating alone cannot continue to change the blood pH.
Eating green leafy vegetables is good for health, but has nothing to do with pH.
Rumor 5: Eating sweets is good for cellulose growth.
Soy loves to “eat” sugar. Sugar will “nourish” high-molecules, so eat less sugar.
The truth: Carbohydrates, also called glucose, are broken down into glucose in the body, providing energy for cell activity.
All cells need glucose to provide energy, and because nanoparticles grow faster than normal cells, the amount of glucose required.
But this does not mean that the sugar in the confection will be exclusively used as a “replacement” by the polymer.
The body cannot decide that the cell should get some kind of nutrients.
Of course, limiting the intake of sugary foods can prevent weight gain and maintain health.
Myth 6: “Superfoods” can prevent cancer.
Blueberries, broccoli, garlic, green tea . These anti-cancer foods have high expectations, and some people only eat certain types of foods, hoping to stay away from tumors.
The truth: Some studies have found that certain foods or certain nutrients are indeed related to the low incidence of cancer, but it does not make sense to count on a specific food to prevent cancer.
The human body is very complex, as is the occurrence and replenishment of cancer.
However, there is evidence to show that eating a variety of plant-based foods, such as vegetables, fruits, whole grains, and beans, leads to a reduced risk of various cancers.
Therefore, it is very useful to make these foods part of a healthy diet.
Rumor 7: Mobile phones and sweeteners can cause cancer.
There are many daily necessities and food additives that have been on the black list of carcinogens, such as mobile phones, artificial sweeteners, hair dyes, etc.
Truth: The National Cancer Institute report states that there is no evidence that sweeteners can cause cancer or pose any other health risks.
Data released by the National Institutes of Environmental Hygiene show that there is no conclusive evidence to prove the carcinogenicity of mobile phone radiation.
However, some studies have found that certain fractions of ionizing radiation and hair dyes and additives may cause cancer after reaching a certain dose.
However, as long as the additives are used in accordance with national regulations, they can be used with confidence.
Do not use the phone continuously for too long, don’t put it on the bed when you sleep, just a hand.
Rumor # 8: Advanced cancer treatment is useless.
Cancer is not cured at an advanced stage. It is so painful to see the patient. It is better to go home and eat something.
Truth: Advanced cancers are indeed difficult to cure, but other advanced cancers may be cured through standardized treatments, such as chorionic cancer, insulin pill germ cell tumors, malignant lymphomas, etc.
Although most advanced cancers cannot be cured, effective treatment can prolong survival and improve quality of life, and the median survival time of advanced advanced bowel cancer can be increased to more than 24 months.
In addition, a good mentality is the commonality of “miracles”.
It is recommended that patients with cancer do not always treat themselves as patients, maintain a normal life as much as possible, and even continue their original work.
