Lymphoma has an “affinity” for some people, and susceptible people need to beware Lymphoma is currently one of the fastest growing malignancies in the world, with the ninth highest incidence rate and an average of one new patient every two minutes. In the past 20 years, the global incidence rate has increased by 75%. The male to female ratio is about 1.3 to 1.4:1. The age of onset is bimodal, with the first peak at 15-35 years old and the second peak after 55 years old. In the past, the incidence rate was high in rural areas, but now the incidence rate is increasing year by year in urban areas, especially among white-collar workers, scientific and technical personnel and people with high life stress. The existing research suggests that the various factors causing lymphoma are divided into the following aspects: the first aspect is bad living habits: irregular life, frequent late nights, Internet cafes, long-term smoking, and drinking coffee and strong tea on an empty stomach. The second aspect is the history of close contact with harmful substances: including exposure to chemical factors and occupational exposure. First, exposure to chemical factors: (1) Hair dyes contain a large amount of benzene. According to the American Cancer Society, women who use permanent hair dyes have a 70% increased chance of developing lymphoma, and transient hair dyes have a 40% increased chance. (2) Living in a newly renovated house, because many of the renovation materials in benzene and formaldehyde and other harmful substances seriously exceed the standard. Second, occupational exposure: (1) drivers with long-term exposure to gasoline containing benzene; (2) painters with long-term exposure to paint; (3) radiologists and other people with long-term exposure to medical or industrial radiation, receiving excessive doses of exposure; (4) fruit farmers with long-term exposure to pesticides and other harmful substances. (5) Office workers frequently receive radiation from computers and cell phones due to their work, and night shifts cause excessive fatigue. The third aspect is the influence of mental factors: excessive spiritual and psychological stress, long-term depression, sadness, pain, anxiety and self-restraint and a very introverted personality of the population. (1) white-collar workers who are in a state of long-term physical and mental depression due to excessive business targets. (2) Candidates who have a mental breakdown due to the pressure from parents and social superiority. (3)The so-called successful people who pursue too much and perfection in all aspects of society, etc. (4) Sudden changes, such as emotional deception, the departure of relatives, shock, car accidents, etc., and the lack of psychological rescue. The fourth aspect is the environmental factors: First, the natural environment: some areas have long years of water pollution, relatively backward economy, lack of nutrition in the diet. Second is the man-made environment: long-term exposure to noise, garbage pollution in the noisy environment. The excessive pressure of life and the accelerated pace of society make people inadvertently put on the hat of lymphoma, which is really unpreventable. How to cut off these invisible killers? First of all, start from yourself, reasonable diet, moderate exercise, quit smoking and limit alcohol, and psychological balance. Secondly, under the scientific guidance of doctors, prevent and actively treat viral infections, chronic lymphadenitis and autoimmune diseases. Those who have similar diseases in their family members should be highly alert. At the same time, relax and live a peaceful life.
