"Oh, original period cannot wash your hair," white-collar Miss LI recently mailbox, often receive such mail, usually colleagues and friends.

This kind of "not how, otherwise it will cause cancer" posts, in all the major social networking sites have also been numerous trainers, some say, sounds very reasonable. While these have specialized journalists under? asked by Chinese Academy of medical sciences, Director of the original cancer Yuan Fenglan, Tianjin cancer tumor prevention Medical Center Director photographer vision field, a hospital male Director Guo, Harbin Institute of technology Professor of urban and environmental engineering, and other experts, the horse will be reading these rumours. Experts pointed out that these Internet rumors spread of cancer that most errors, the annual cancer check-up is the best way to prevent cancer.

Rumor: menstrual shampoo will cause cancer

Source: recently a information for many people fear, which refers to: menses, can't shampoo, cannot eat cold food, so as not to give discharge of sewage discharge of blood without the net, but left in the uterus, cumulatively, hormones secretion disorder, while the incidence of breast cancer and uterine cancer.

Expert interpretation: right.

Hormone (endocrine) disorders are not caused by the menstrual cycle, and with the physical, psychological, environmental and genetic factors. The cancer and the human life environment and life habits, if menstrual period do not pay attention to lifestyle, can cause congestion in the long period of time can cause disease, but it does not have cancer.

Women during menstrual period, resistance drop, if the body is affected, being stagnant blood, can cause menstrual or dysmenorrhea, therefore, would not be appropriate for the affected period, blowing rain water, cold feet or cold bath, do not eat raw food, these are reasonable.

But a warm shower shampoo has no effect on health in full.

Rumor 2: only the Khan of carcinogenic

Source: Internet rumours: hidroschesis agent can cause breast cancer.

There is a saying: dark or RIM's underwear can cause breast cancer. Consumers should how to tell?

Expert interpretation: about wearing underwear or steel ring underwear cause breast cancer, medical research currently does not have any of that.

Previously suspected dyes can lead to bladder cancer, but there is no study finds dark underwear and breast cancer. As for another network rumors pointed out that wearing a hoop of underwear, "are not dead nerve some, much less rib deformation." Experts said that the causes of breast cancer and genetic and acquired environmental carcinogen exposure, there are many factors involved, but it has nothing to do with nerves.

The network also has about only Khan and breast cancer-related rumors, experts point out that the causes of breast cancer is possible and is closely related to female hormones.

The study found that breast cancer patients are mostly of menarche earlier, climacteric late, late childbearing age, or the use of female hormones. Carcinogenic factors, the evidence after a lab with epidemiological studies to set up. People should not be credulous network specious, self-righteous.

Rumor 3: repeat the carcinogenic with mineral water bottles

Source: online news, U.A.E. a 12-year-old girl 16 consecutive months using the same water bottles and drink water, then with cancer, it was considered a bottle inside the plastic material.

Expert interpretation: this is lame, because now qualified mineral water bottle material is organic polymer, in the daily life conditions are relatively stable.

Unless specific conditions in the laboratory, chemical reactions to occur so that harmful substances emitted to a certain extent may have carcinogenic risks, but response even in laboratory conditions will not occur at once, so the life chances of cancer using will basically zero.

Of course, some use unqualified materials production of mineral water bottles, in high-temperature, acidic conditions, such as with hot water, acid, sour plum soup, vinegar, and so on, may have chemicals leaching, occasionally drink once or twice, nor on the body causing great harm, after all, mineral water bottles is plastic products.

Put hot water will deformation, most people do not repeat with a dozen or so months, used for vinegar is also a small number of families.

Rumor: one-time paper cups carcinogenic

Source: long-term use fluorescent agent exceeding paper cups with fluorescent whitening agent, once inside the human body, can induce cell mutation, weaken the personal immunity, even possibly carcinogenic.

Expert interpretation: this type of cancer is two conditions, first fluorescent agent exceeding, the second is the long-term use, both conditions are met simultaneously, will have a certain risk,? there is to be studied.

But what is certain, no cancer is not a single factor or the accumulation is within a short period of time.

Since September 1, 2009 onwards, the State, did not receive QS flags of paper listing the sales, use, is prohibited.

The identity of a QS, production materials of various indicators are qualified, without too much worry about the problem of excessive fluorescent agent.

Selected paper cups to be optimistic about the QS identity, if you purchased a small vendors on paper cups, resolved fluorescence agent is also very easy, with paper cups in the fluorescent lamp take a picture, under clearly appear blue, fluorescence of content is not less, consumer or not to buy it.
