Why Is Pancreatic Cancer So Difficult to Treat — and Where Is the Hope

  Why Is Pancreatic Cancer So Difficult to Treat — and Where Is the Hope? Over the past several decades, advances in medicine, surgery, targeted therapy, and immunotherapy have dramatically improved survival rates for many cancers. Yet pancreatic cancer remains one of the deadliest malignancies. Despite years of research, the prognosis for pancreatic cancer patients is still poor compared with many other tumor types. In the United States, pancreatic cancer consistently ranks among the leading causes of cancer-related death, even though it is not among the most common cancers. Why has pancreatic cancer been so difficult to defeat? And where does the hope for future breakthroughs lie? Scientists generally believe that three major biological challenges are responsible: 1. Pancreatic cancer is extremely difficult to detect early 2. There has long been a lack of effective targeted therapies 3. The tumor microenvironment forms a powerful protective barrier At the same time,...

Can Breast Cancer Patients Survive Long-Term Without Surgery?

  For many people, surgery has long been viewed as the essential step in curing cancer. The common belief is simple: if the tumor can be removed, there is hope for a cure. However, advances in modern cancer therapy are beginning to challenge this traditional view. With the rapid development of neoadjuvant therapy — treatment given before surgery — some breast cancer patients are achieving remarkable responses. In certain cases, tumors completely disappear after drug treatment alone, raising an important question: If no cancer can be found, is surgery always necessary? A recent study led by MD Anderson Cancer Center explored this possibility in patients with early-stage breast cancer. The study focused on patients with triple-negative breast cancer or HER2-positive breast cancer who had undergone standard neoadjuvant therapy. After treatment, researchers performed image-guided needle biopsies of both the original tumor site and surrounding lymph nodes. Among the 50 patients en...

  What foods contain estrogen? Can you eat it? Especially for some breast cancer patients, there are many legends about this topic, and everyone is particularly concerned about two issues: 1: Does soy milk contain estrogen? Is it safe for women to drink? 2: Which foods contain estrogen? 1)       Let's answer the first question first. The reason why soy products are questioned is because soybeans contain a substance called isoflavones, whose chemical structure is close to that of human estrogen, so it is called phytoestrogens. So if there are too many isoflavones, will it play the role of human hormones, and even cause breast cancer or ovarian cancer? This is a very reasonable scientific question. Fortunately, soy products are widely eaten as food around the world, and people all over the world care about it. Therefore, there is a lot of research data to examine whether soy products can cause breast cancer. But this kind of research is not ...

  How to improve immunity? Not lowering is king.   Such a question is often asked: how to improve immunity? When the body's immunity is low, the body is prone to disease symptoms. The most common of these symptoms is infection . Because the immune system is weakened, the immune system cannot properly remove pathogenic microorganisms, which will lead to the occurrence of infection, and it is difficult to heal itself. In addition to infection, weakened immunity may also increase the risk of developing tumors. Tumors are cancerous from their own cells under certain conditions. If the immune system is normal, it will have a certain inhibitory effect on tumor cells, thereby preventing the occurrence of tumors. Conversely, when a person has a weakened immune system, the risk of developing tumors increases. Because immunity is related to many diseases, it has attracted people's attention. So, how can we improve our immunity? Before answering this question, let’s first und...
