In daily life, people often get nervous first when tumors are mentioned. Tumor is a relatively troublesome disease, but there are also benign and malignant. To understand tumor and scientific prevention, we should start from understanding the difference between benign tumor and malignant tumor. What is benign tumor? Benign tumor refers to the abnormal proliferation of cells in certain tissues in the body, which is swelling and growing like a balloon, and the growth is slow. As the tumor increases continuously, it can squeeze the surrounding tissues, but does not invade the adjacent normal tissues, and it is mostly spherical and nodular in shape. Therefore, it can be easily removed during surgery, and it does not metastasize and rarely recurs. What is malignant tumor? In medical science, cancer refers to malignant tumor originating from epithelial tissue, which is the most common type of malignant tumor. Correspondingly, malignant tumors originating from mesenchymal tissues are collectively called sarcomas. There are a few malignant tumors that are not named according to the above principle, such as nephroblastoma and malignant teratoma. The term “cancer” is generally used to refer to all malignant tumors. The difference between benign tumor and malignant tumor 1.Whether metastasis occurs Generally, those tumors that do not metastasize in the body are mostly benign tumors, except for malignant tumors that are discovered at very early stage, others have spread in the body. 2.The growth rate of tumor Most benign tumors grow slowly, and some benign tumors even begin to degenerate or stop growing slowly by themselves, on the contrary, the growth rate of malignant tumors is quite rapid. 3.Most malignant tumors do not have envelope. In the process of growth, it is easy to invade the surrounding organs to form adhesions and bring influence to the surrounding normal tissues and organs. 4. Effects of both on the body Benign tumors show swelling growth, and later on the tumor will compress the surrounding organs because it is too big and make the patient feel uncomfortable, but it mostly shows some local symptoms; compared with malignant tumors, which have strong spreading and metastatic destructive power to the body organs, the patient is prone to lose weight, anemia, cachexia and many other clinical manifestations, and even endanger the patient’s life soon. What should we do if we have benign tumor? When benign tumor grows in the vital parts of the body and the space in these parts is quite limited, it can also cause fatal consequences. For example, huge benign tumors growing in the skull, thyroid gland and mediastinum, etc. Benign tumors in the gastrointestinal wall or intestinal cavity can also cause obstruction, bleeding, perforation, jaundice and other emergencies because of the enlargement of the tumor, and delayed treatment can lead to death. Some benign tumors can become malignant and once they become malignant, the consequences are the same as malignant tumors. The tumors that are more prone to malignant change are thyroid adenoma, breast fibroid, uterine tumor, flat bone myoma of gastrointestinal tract, soft tissue fibroid, synovial tumor and ligament fibroid. Once these tumors are found, they should also be dealt with in time. Some benign lesions of non-tumor diseases are also related to malignant tumors, such as cystic lobular hyperplasia of breast, nevus, scarring lesions of lung tissue or other parts, long-term untreated chronic ulcers, liver cirrhosis, etc. may be related to the occurrence of malignant tumors. Therefore, if a benign tumor is found to have rapid enlargement, bleeding and severe pain, you should go to hospital immediately for examination and surgical removal if necessary. What to do if you have malignant tumor? Cancer is a physical and spiritual disease, therefore, having a forward and positive mindset can turn a “cancer fighter” into a victorious angel, as complaining and suffering will increase the acidity in the body, so learn to relax and cherish life. Even for patients with advanced cancer, they should try to live a quality life, get more sunshine, do exercises within their ability, and improve their motivation to fight against cancer, so that a cheerful state of mind is very beneficial to the treatment of cancer. 2. Do not delay treatment by hearsay For cancer patients, the timing of treatment is very important. Cancer cells spread quickly and metastasize easily, and when cancer enters advanced stage, treatment is difficult and there is little hope for cure in general. Therefore, if you have cancer, you should not listen to charlatan doctors and all kinds of prescriptions, and you should not take all kinds of tonic drugs indiscriminately, so as not to miss the best time for treatment. 3. Choose treatment according to your condition and avoid over-treatment. Trust your doctor and let him/her make scientific treatment plan according to your physical condition and illness, and do not “over-treat” because you are in a hurry. Some patients with advanced cancer have metastasized and spread in many places, so surgery is not possible in this case. If the patient is in good mental condition and there are no fatal complications, obstruction or hemorrhage, there is no need for surgery; in addition, some patients have been treated with repeated chemotherapy, resulting in low white blood cells, mental pain and physical weakness, so continuing chemotherapy at this time will greatly increase the patient’s pain and accelerate the patient’s death.
