1.How to detect early cancer
Generally speaking. It is very difficult for patients to detect early cancer, unless the cancer cells are located in the body surface, oral cavity, breast and other easy areas. In the early stage of cancer, cancer cells are very limited and there are no nerve fibers in the cancer tissue, so there are no obvious symptoms or no symptoms at all. When the cancer cells proliferate to a certain extent and invade the peripheral nerves and blood, a series of symptoms will appear, and at that time, the cancer is basically in the middle or late stage. Therefore, in order to detect early cancer, the most effective way is to have a comprehensive physical examination on time, usually once a year. It is especially important for those who have family history.
2. Importance of early detection of cancer
A lot of clinical practice proves that the key to prevention of malignant tumors lies in early detection, early diagnosis and early treatment. Among them, early detection is the prerequisite for early diagnosis and early treatment. At present, malignant tumors can be completely cured only by striving for early treatment. If the tumor develops to the middle or late stage, or the tumor tissue expands or has metastasized, even if various treatments are taken, it is difficult to achieve the purpose of eradication. If the tumor can be detected at early or relatively early stage and before metastasis occurs and given reasonable treatment in time, a considerable number of patients can achieve the expected treatment effect. Even a cure can be achieved.
3.Twelve measures to prevent tumor
(1) Nutritional intake should be balanced, no partial food, no partial taste.
(2) Daily diet should be varied, not to eat the same food or take the same medicine for a long time.
(3) Avoid over-eating and moderate fat intake.
(4) Try not to drink alcohol, especially not alcoholic.
(5) Eat more vitamins and fiber foods, such as vitamins A, C and E, etc.
(6) Smoke less or quit smoking.
(7) Eat less pickled food and no overly hot food.
(8) Do not eat burnt food or moldy food.
(9) Avoid strong sunbathing and ultraviolet radiation on the skin
(10) Proper physical exercise, do not be overly tired.
(11)Be hygienic and keep your body clean.
(12) Participate in more meaningful activities and maintain a healthy mental state;
4.Two major factors that induce oncology
(1) External carcinogenic factors.
A, chemical carcinogenic factors B physical carcinogenic factors C, biological carcinogenic factors D, chronic stimulation.
(2) Intrinsic carcinogenic factors
A, genetic factors B racial carcinogenic factors C, gender and age D, genes E, low immune function.
5.Who are the people with high incidence of cancer
Generally, it refers to a certain group of people who are prone to cancer intrinsic factors and those who are in a certain environment of carcinogenic factors for a long time such as
(1) People with family and hereditary diseases of cancer: such as people with certain chromosomal abnormalities of hereditary diseases.
(2) People with cancer-related diseases: such as those with long-term chronic gastritis, cervicitis, hepatitis B, skin ulcers, etc.
(3) People with bad habits: such as long-term smoking, alcoholism, preference for overheated and irritating foods, etc.
(4) Occupational susceptibility groups: such as long-term exposure to medical or industrial radiation, long-term inhalation of industrial exhaust, and people in areas with severe air pollution.
(5) Personality traits susceptible people: people with long-term depression, sadness, strong self-restraint and introversion.
6.UV and cancer
For a long time, many people think that the sun-tanned skin is a sign of good health. However, medical research shows that tanned skin does not improve health. The ultraviolet rays of the sun irradiated on the skin, not only easy to cause dermatitis, long-term exposure may also lead to the occurrence of skin cancer. Because ultraviolet rays acting on the skin can have a negative impact on the chromosomes in the skin cells, causing cell mutations and thus cancer.
7.Is it easy to get cancer if you dye your hair frequently?
Most of the hair dyes used in the market are synthetic dyes of paraphenylenediamine, which are scientifically proven to be carcinogenic when used for a longer period of time. Leukemia is a long-standing disease of the hematopoietic system, and its pathogenesis, such as malignant tumors, is related to long-term exposure to toluene and arsenic agents. In view of the above, you should try to avoid long-term use of hair dyes.
8.Smoking and cancer
Smoking is harmful to health cigarettes are lit, the smoke contains mainly tar, nicotine and other harmful substances, and tar 3.4 a benzo(a)pyrene is a very strong carcinogenic substances, experiments with it coated in the trachea of rats, skin can induce lung cancer, skin cancer. Cigarettes contain arsenic, which is an important factor in triggering testicular cancer, and it contains methyl substances, which are also important substances that induce rectal and bladder cancer, to a certain extent, smoking is equivalent to inhaling carcinogenic substances. Smoking not only harms you, but also brings passive smoking to the people around you, so for the sake of your health and others, please
Please quit smoking for the sake of your health and the health of others.
9.How to prevent family cancer
(1) Reduce the cancer-causing factors in your life, for example, if your parents smoke and suffer from lung cancer, they will pass on their susceptibility to the cancer-causing substances in cigarettes to their children, and if their children smoke and suffer from cancer, their chances of getting cancer will increase significantly.
(2) Maintain the immunity of the body, parents suffering from cancer will make some of their children threatened, in order to prevent cancer should keep the body in a healthy level.
(3) Carry the burden of mind. Keeping psychological health is also an important way to prevent hereditary cancer. Bad psychological and mental state can weaken the immunity of human body and cause internal environment disorder and become the triggering factor of some family cancers, so it should be avoided as much as possible.
10.What lifestyles can help prevent cancer
Establish a good living environment, reduce the exposure to harmful substances and gases, promote the construction of spiritual civilization, maintain a good psychological state, clean oneself, establish normal and harmonious interpersonal relationships, eliminate bad living and eating habits, eat reasonably, and do not eat partially or overeat. Quit smoking, drink alcohol appropriately, strengthen physical exercise to maintain a normal weight, and develop a practical work and rest schedule according to your work and physical condition. For the sake of your health, start from now.
11.Can cancer be hereditary?
Among human malignant tumors, those that are obviously hereditary exist but are rare. Nowadays, some cancers or precancerous lesions that show dominant and recessive heredity have been found, such as colon cancer, skin cancer, breast cancer, ovarian cancer, and primary tumors, etc. The hereditary tendency is more significant. However, the inheritance pattern is quite special. It is not directly inherited, but the susceptibility to malignant tumors is inherited, that is, not the tumor itself.
