What is it about cancer that makes medicine so powerless?

Actually cancer is not a disease but it is the common name for a group of different diseases, each with its own characteristics. In general, cell growth and division are abnormal, even terrible, and disrupt the structure of the body. Cancer, after appearing in a certain area, can spread to other attacked areas. other organs through swimming in the blood. Cancer is one of the leading causes of death in the world and poses many challenges for diagnosis and treatment. In fact, cancer treatment is extremely complicated for the following reasons. First, cancer is so diverse and complex. As mentioned, cancer is not a single disease but a common disease of more than 200 different types of diseases, each type of cancer. Cancer also has many subtypes and they have different genetic and molecular characteristics. Therefore, we can understand that there will not be one treatment method that can be applied to all types of cancer. You cannot use one type of dipping sauce for all types of foods. For example, there are many different types of breast cancer such as triple-negative breast cancer, Hormone-positive breast cancer or H2-positive breast cancer. Breast cancer has different ways of developing and metastasizing and responds to different drugs. Therefore, the choice of treatment for each type of cancer is also different for a reason. I feel very confused and have a headache, but the cancer treatment still has many problems. Please continue reading. The second reason why cancer is difficult to treat is due to the unpredictable changes of cancer cells like Sun Wukong. Cancer cells have the ability to mutate and adapt to their surroundings, causing them to become resistant to drugs or treatments to the point that many cancer cells per tumor are no longer the same. called cellular heterogeneity, this makes it extremely difficult to identify and destroy all cancer cells. For example, some cancer cells can mutate bref, a gene involved in cell growth. Drugs that target Br AF can be effective in stopping the growth of these cell types however not all cancer cells have the Br AF mutation. For non-brafs, it continues to live and spread to attack the body, but we are much more than that. The reason cancer is difficult to treat is because of the similarities between cancer cells and human cells. Typically, although you see cancer cells function differently from most normal cells because they grow and divide very quickly, they are generally different from normal cells, but the differences are not that great. This makes cancer treatment difficult because it is difficult to target cancer cells without affecting normal cells. For example, some drugs target factors that stimulate cell growth. such as V egf or egf However, these factors are found not only in cancer cells but also in normal cells. Therefore, the use of these drugs can cause side effects such as high blood pressure and inflammation. damage to the skin or liver, it is like anti-virus software that regularly deletes the brush file, then deletes the data file, and after killing the virus, it also damages the computer. In addition, cancer that is considered cured is only considered cured when there is no trace of it left in the body and it will never return or is expected not to return but is difficult to know for sure that it will not recur. For example, some types of cancer such as leukemia or lung cancer can hide in the body for a year after treatment and it will reappear with greater strength so it is not considered completely cured. all cancer. But even with these 4 reasons, you shouldn't worry too much. Medicine and science in general have made many advances in recent years and have resulted in many new treatments that are more effective than traditional methods. Treatments that target specific characteristics of cancer cells or factors related to the body's immune system have shown very positive results in controlling and slowing cell progression. cancer. As the disease progresses, these methods also have fewer side effects than traditional treatments you often hear about such as chemotherapy or radiotherapy. We can mention new cancer treatment methods such as pepbrolyzema or neveruma that can activate the body's immune system to recognize and destroy cancer cells. These drugs are already ours. effective in treating some types of cancer such as skin cancer and lung cancer. In addition, early detection and accurate diagnosis are also important factors that help increase the chance of saving patients' lives and many new technologies are born such as genetic analysis of a cell or the use of machines and intelligence Artificial intelligence for big data processing has opened up new possibilities for better understanding. Due to the nature and diversity of cancer, these technologies also help select and monitor the right treatment for each patient. For example, single-cell genetic testing can help identify cancer cell-specific mutations and select drugs that target them. Use machine-assisted analysis of clinical and biological data to make predictions about treatment outcomes and disease recurrence. In short, cancer is a very difficult disease to treat because the causes are related to similar cell changes and are difficult to identify. However, this does not mean that we have no hope. Thus, the fight against cancer by combining advanced scientific and technological knowledge and collaboration between researchers, doctors and scientists has moved closer to the goal of control and cure. Cancer Surely many people will be saved from this evil and hopefully in the future this side will be cured. Thank you for reading, goodbye and see you again.
