Over the past year, we have been receiving frequent phone calls and online consultations about skin cancer. Every week, patients come to the clinic to register to see if they have skin cancer and are very fearful, and it takes patient explanations to dispel their worries. So, why do so many people suspect they have cancer? This is what a netizen wrote to me: “I have had a mole for many years, but recently I was very scared after learning about mole cancer through the Internet, and then I accidentally found a mole on my nose with irregular jagged edges, but it didn’t increase in size, so I was scared to death. I don’t know if the pressure from the prosthesis caused the mole on the tip of my nose to change. I didn’t pay attention to it before. The pressure of the skin opening up will cause stimulation to the mole, and many of the moles that have been there are growing again, and some are not clean, there is still a little left but they don’t continue to grow. ” There is nothing wrong with going online to learn about medical knowledge and increase your awareness of precautions, but the key is how to properly understand and digest the medical knowledge on the internet. For many optimistic people, when they see something about cancer, they may actively think in a good way, while for anxious and nervous type of people, or people suffering from cancer, they always look at the problem in a bad way, always think in a serious way, a little bit of small things may be magnified, and for problems that may be only one percent he will also be infinitely magnified and anxious. Why does this happen? This is because for laymen who have no practical experience or students who only read with book knowledge, they cannot understand what the real cancer or melanoma looks like clinically and how it develops, which is often different from what is described in books, and they often look at the descriptions in books or on the Internet to match themselves, and the more they look like them, the more they are convinced, especially nowadays the knowledge on the Internet is hard to distinguish between real and fake, and many of them, out of For patients without clinical experience or laymen, it is difficult to distinguish right from wrong, so they are easily trapped and cannot extricate themselves from the situation. Even if they have been cured, they still suspect that the cancer has spread, and even if there is a little change in themselves, they will think about the spread of cancer. In the end, it is the Internet that disturbs people’s mentality and induces the occurrence and development of “cancer”. In fact, the Internet is not credible, and we should face it correctly. Even if you have melanoma, skin cancer or other cancers, as long as you treat them actively in the early stage, they are completely curable. Even if the cancer is late, with the cooperation of modern technology, positive and optimistic attitude and confidence to overcome the disease, late stage cancer can be cured. We should learn to surf the Internet happily and let the Internet bring us good mood and good knowledge; we should not rely on the Internet, surf the Internet frequently and always look for serious problems to see, and family members or friends with cancer should not pass serious problems and bad negative contents on the Internet to patients or people who suspect they are cancer or melanoma, so that they will not induce “the appearance and spread of cancer” due to the Internet. “.
