The Differences And Connections Between Tumors And Cancers

1. Huateng Pharma https://en.huatengsci.com The Differences And Connections Between Tumors And Cancers Cancer is a terrible disease with high morbidity and mortality. In daily life, many people compare tumors with cancers, and think that if they grow tumors, they are suffering from cancer. Others believe that malignant tumors are cancers. What are the facts? What are the differences and connections between tumor and cancer? On the whole, tumors and cancers are both related and distinct. The two are different diseases and should not be confused. In simple terms, we can use several formulas to express the relationship between tumors and cancer: Tumor = benign tumor + malignant tumor Malignant tumor = carcinoma + sarcoma Malignant tumor = cancer

2. Huateng Pharma https://en.huatengsci.com Tumor A tumor is an abnormal lump or neoplasm that grows out of cells in the body that divide and proliferate more than normal, or cells that should die under normal circumstances have not died. According to the degree of tumor differentiation, as well as recurrence and metastasis, it can be divided into benign tumors and malignant tumors. The so-called degree of differentiation refers to the degree to which tumor cells are close to normal cells. The higher the degree of closeness, the higher the degree of differentiation of the tumor and the greater the possibility of benignity. In addition, there is another kind of tumor that is between benign and malignant, called borderline tumor. Benign tumor Benign tumors are those tumors that stay in the original site and do not invade surrounding tissues or other parts of the body, such as uterine fibroids and skin lipomas. Generally, benign tumors will not metastasize or spread to local structures or distant parts of the body. They tend to grow slowly and have clear boundaries. They will not cause great harm to the body and the possibility of recurrence after surgical resection is unlikely. However, some special types of benign tumors can turn into malignant tumors, such as colorectal polyps, which require close monitoring and timely surgical removal. Malignant tumor Malignant tumors have irregular borders. Cells grow rapidly and uncontrollably. They can invade surrounding tissues, spread and metastasize to other parts of the body through the blood or lymphatic system. The most common sites for malignant tumors to spread and metastasize are the liver, lungs, brain and bones. Malignant tumors need timely treatment to avoid spreading. Although malignant tumors tend to grow faster and more dangerous than benign tumors, some benign tumors can also cause serious harm to the human body, such as benign tumors in the brain. It should be noted that some malignant tumors will not form solid tumors,

Malignant tumors derived from epithelial cells are called carcinomas; malignant tumors derived from mesenchymal tissues are called sarcomas. Carcinomas Carcinoma is the most common type of malignant tumor, formed by epithelial cells. Epithelial cells are cells on the surface of the human body's skin or the surface of the internal cavity. There are many types, and they are often columnar when viewed under a microscope. Carcinomas originating from different types of epithelial cells have different names, such as adenocarcinoma, basal cell carcinoma, and squamous cell carcinoma. Adenocarcinoma is a cancer formed in epithelial cells that produce fluid or mucus, and tissues with such epithelial cells are sometimes called glandular tissues. Most breast, colon and prostate cancers are adenocarcinomas. Basal cell carcinoma is a malignant tumor that starts in the lower or basal layer of the epidermis (skin) and is the most common skin malignant tumor. Squamous cell carcinoma is a malignant tumor formed in squamous cells. Squamous cells are located in the epithelial cells just below the outer surface of the skin. They are also arranged on many other organs, including the stomach, intestines, lungs, bladder, and kidneys. When viewed under a microscope, squamous cells look like fish scales. Squamous cell carcinoma is sometimes called epidermoid carcinoma. Transitional cell carcinoma is a type of cancer that forms in epithelial tissue called transitional epithelium, or urothelium. This tissue is composed of multiple layers of epithelial cells, which are found in the lining of the bladder, ureter, part of the kidney (renal pelvis), and a few other organs. Some bladder cancer, ureteral cancer, and kidney cancer are transitional cell carcinomas. The name of the cancer is usually based on the organ or tissue in which it originally formed. For example, lung cancer starts in lung cells, and stomach cancer starts in stomach cells. Cancers can also be named by the cell types that

Huateng Pharma form them, such as lung squamous cell carcinoma, lung adenocarcinoma, gastric adenocarcinoma, gastric squamous cell carcinoma, etc. https://en.huatengsci.com Sarcoma Sarcoma is a malignant tumor formed in the mesenchymal tissue of cartilage or soft tissue. Soft tissues include muscle, fat, blood vessels, lymphatic vessels, and fibrous tissues (such as tendons and ligaments). Osteosarcoma is the most common cartilage malignant tumor. The common types of soft tissue sarcoma are leiomyosarcoma, Kaposi's sarcoma, malignant fibrous histiocytoma, malignant liposarcoma and dermatofibrosarcoma protuberans. In addition, leukemia, lymphoma, multiple myeloma, melanoma, and some brain and spinal cord tumors are also malignant tumors. People often use cancer to refer to malignant tumors, including carcinomas and sarcomas. When people talk about malignant tumors, they often omit the word "malignant" in front and only talk about "tumor". This is one of the reasons why people sometimes cannot distinguish between the two names "cancer" and "tumor". In daily life, if a doctor says that someone has cancer, it means that he has a malignant tumor; if he says that he has a tumor, it does not mean that he has cancer, it is most likely a benign tumor. Of course, we have adopted a simplified method here. In fact, the classification and naming of tumors are much more complicated. In order to make it easier for everyone to understand, we have omitted many tumor types in the middle gray area. All in all, whether benign tumors or malignant tumors are found, they should be treated as soon as possible to prevent benign tumors from developing into malignant tumors and metastasis of malignant tumors to other organs. The earlier the treatment, the less damage. As a reliable pharmaceutical intermediates supplier, Huateng Pharma is able to provide the services of Anti-Cancer intermediates's process development and scale-up production with capacities varying from gram to kilograms and multi tons. We have our own industrial park of 34,000 square meters that has been completed and put into operation since 2020 to support multi tons production.
